Regenerative, bidirectional “Green” Power Solution

The RS Series features the ability to both source and sink current, i.e. bi-directional current flow. The RS amplifier is designed to reverse the phase relationship between the AC input

Avionics
With an output frequency range to 819 Hz (or 905 Hz with -HF option), the RS Series is well suited for aerospace applications. Precise frequency control and accurate load regulation are key requirements in these applications. The available IEEE-488 remote control interface and SCPI command language provide for easy integration into existing ATE systems. The RS Series eliminates the need for several additional pieces of test equipment, saving cost and space. Instrument drivers for popular programming environments such as National Instruments LabView™ are available to speed up system integration.

Regulatory Testing
As governments are moving to enforce product quality standards, regulatory compliance testing is becoming a requirement for a growing number of manufacturers. The RS Series is designed to meet AC source requirements for use in compliance testing such as IEC 61000, 3-2, 3-3, 3-11, 3-12, to name a few.

Choice of voltage ranges
The RS Series includeds 150V and 300V line to neutral. These models provide 3 phase output capability of 260 Vac or 520 Vac line to line respectively.

For applications requiring more than 300 V L-N (or 520 V L-L), the optional -HV output transformer provides an additional 400 V L-N and 693 V L-L output range for use in AC mode only.

High Crest Factor
With a crest factor of up to 3.6, the RS Series AC source can drive difficult nonlinear loads with ease. Since many modern products use switching power supplies, they have a tendency to pull high repetitive peak currents. The RS90 can deliver up to 720 Amps of repetitive peak current (150 V AC range) per phase to handle high crest factor three phase loads.

Remote Control
Standard RS232C & USB IEEE-488 along with optional LAN remote control interfaces allow programming of all instrument functions from an external computer. The popular SCPI command protocol is used for programming.

Application Software
Windows® application software is included. This software provides easy access to the power source's capabilities without the need to develop any custom code. The following functions are available through this GUI program:

• Steady state output control (all parameters)
• Create, run, save, reload and print transient programs
• Generate and save harmonic waveforms
• Generate and save arbitrary waveforms
• Measure and log standard measurements
• Capture and display output voltage and current waveforms
• Measure, display, print and log harmonic voltage and current measurements [iX only]
• Display IEEE-488 or RS232C bus traffic to and from the AC Source to help you develop your own test programs.

1. Requires PC running WindowsXP™ or Windows 2000™ / 2007.

Harmonic Waveform Generation
Using the latest DSP technology, the RS Series programmable controller is capable of generating harmonic waveforms to test for harmonics susceptibility. The Windows Graphical User Interface program can be used to define harmonic waveforms by specifying amplitude and phase for up to 50 harmonics. The waveform data points are generated and downloaded by the GUI to the AC source through the remote interface. Up to 200 waveforms can be stored in nonvolatile memory and given a user defined name for easy recall.

All RS Series configurations offer three phase waveform generation, allowing independent phase anomalies to be programmed. It also allows simulation of unbalanced harmonic line conditions.
 

Arbitrary Waveform Generation
Using the provided GUI program or custom software, the user also has the ability to define arbitrary AC waveforms. The arbitrary waveform method of data entry provides an alternative method of specifying AC anomalies by providing specific waveform data points. The GUI program provides a catalog of custom waveforms and also allows real-world waveforms captured on a digital oscilloscope to be downloaded to one of the many AC source's waveform memories. Arbitrary waveform capability is a flexible way of simulating the effect of real-world AC power line conditions on a unit under test in both engineering and production environments.

RS Series - AC and DC Transient Generation
The RS Series controller has a powerful AC and DC transient generation system that allows complex sequences of voltage, frequency and waveshapes to be generated. This further enhances the RS's capability to simulate AC line conditions or DC disturbances. When combined with the multiphase arbitrary waveform capabilities, the AC and DC output possibilities are truly exceptional. Transient generation is controlled independently yet time synchronized on all three phases. Accurate phase angle control and synchronized transient list execution provide unparalleled accuracy in positioning AC output events.

Transient programming is easily accomplished from the front panel where clearly laid out menu's guide the user through the transient definition process.

RS Series - Measurement and Analysis
The RS Series is much more than a programmable AC, DC or AC+DC power source. It also incorporates an advanced digital signal processor based data acquisition system that continuously monitors all AC source and load parameters. This data acquisition system forms the basis for all measurement and analysis functions. These functions are accessible from the front panel and the remote control interface for the RS Series.

Conventional Measurements [All controllers]
Common AC and DC measurement parameters are automatically provided by the data acquisition system. These values are displayed in numeric form on the front panel LCD display. The following measurements are available: Frequency, Vrms, Irms, Ipk, Crest Factor, Real Power (Watts), Apparent Power (VA) and Power Factor.

Harmonic Analysis
The RS Series provides detailed amplitude and phase information on up to 50 harmonics of the fundamental voltage and current (up to 16 kHz). Harmonic content can be displayed in both tabular and graphical formats on the front panel LCD for immediate feedback to the operator. Alternatively, the included GUI program can be used to display, print and save harmonic measurement data. Total harmonic distortion of both voltage and current is calculated from the harmonic data.

Waveform Acquisition
The measurement system is based on real-time digitization of the voltage and current waveforms using a 4K deep sample buffer. This time domain information provides detailed information on both voltage and current waveshapes. Waveform acquisitions can be triggered at a specific phase angle or from a transient program to allow precise positioning of the captured waveform with respect to the AC source output. The front panel LCD displays captured waveforms with cursor readouts. The included GUI program also allows acquired waveform data to be displayed, printed, and saved to disk.

The 3091LD is designed to provide precisely controlled, non-linear loads for testing AC power generation equipment such as UPS’s and AC sources. In addition, any active or passive current carrying devices such as switches, circuit breakers, fuses, connectors and power semiconductors can be tested. Traditionally, many of these products are tested using resistive load banks. This approach does not simulate real-world conditions such as switching DC/AC converters found in many AC powered products. This type of conventional testing does not fully exercise the equipment under test (EUT) under worst case operating conditions. High peak currents and low power factor loads can significantly impact the operating characteristics of a UPS or AC power product. The 3091LD AC Load can simulate high crest factor and variable power factor load conditions. This provides an effective method of testing AC products against real-world conditions and can significantly increase product reliability. Unless properly exercised, product defects may go undetected until a unit is used at a customer site, resulting in costly field returns.

Traditional DC Electronic Load Solutions are bulky and large in size. Most are offered with standard voltage, current and power ratings. In the ATE world, rack space is a highly coveted asset and application demands are constantly diversifying with new technology development.

AMETEK Programmable Power's PLA Series of “Air-cooled” DC Electronic Electronic Loads offers the industry’s smallest footprint, the highest power density and current rating, along with the broadest selection of high voltage models on the market.

The Elgar Power Special Test Equipment (PSTE) provides programmable DC power, and programmable loading, to the electrical systems of satellites for system functional testing.

There are several key benefits of the PSTE. First, it is a complete turnkey system that is capable of operating locally through a simple GUI interface or remotely via a host computer as a single Ethernet address. The spacecraft engineer who defines the spacecraft power bus limits, cabling scheme, mode simultaneity matrix, and system behavior based upon limit conditions implements the real intelligence of the system. From this definition, operating procedures can be generated to allow spacecraft technicians to operate the system, system protections are implemented that perform cable detection and mode verification, automated spacecraft fixture identification and related mode capability, and more.

Second, the PSTE is intended to negate the need for purchasing new power test equipment with each new spacecraft. With a review of current and future needs and industry trends, power resources can be sized to provide the optimal blend of flexibility and price.

The system also monitors and provides protection for the satellite electrical power systems against any damage by programming error or by system failure.

Hardware Overview

In this section, the overall system is first represented by a simplified block diagram along with a general discussion of the function of each equipment rack. After which, each rack of equipment is represented by its own block diagram. Each rack block diagram is supported by a discussion of the equipment in the rack.

Either the Remote User Interface (RUI) or the Remote Operating System (ROS) is the source of control, or Computer in Charge (CIC), at any given time, at the operator's discretion. The ROS is supplied by the user. The CIC communicates directly with the system controller in the MPR (MPR controller), and the entire system is controlled via the MPR Controller.

Diagnostics and Troubleshooting can be accomplished directly from the MPR controller. The Main Power Rack (MPR) provides main bus power for tests from up to five internal power sources. The Solar Array Simulator (SAS) provides solar panel simulation power. The Spacecraft Protection Unit (SPU) further protects the spacecraft from damage in case of failure of the built-in OVP/OIP protection of the rest of the PSTE system. For electrical system loading tests, the Electronic Load Rack (ELR) provides three programmable Electronic Load Units (ELU). The MPR contains an ELU that can be used when only one ELU is required.

With a full 15 kW available down to 20 V output in a 3U package the SGX leads the industry in power density. The power density is enhanced by a stylish front air intake allowing supplies to be stacked without any required clearance between units.

At the heart of the SGX series is a 5 kW power module. Depending on the output voltage, one to six modules can be configured in a single chassis to deliver 5 kW to 30 kW of power.

Combinations of these chassis can then be easily paralleled to achieve power levels up to 150 kW. Paralleled units operate like one single supply providing total system current.

The Sorensen Asterion line of DC power supplies by AMETEK Programmable Power combines intelligence and flexibility to create an advanced platform of DC solutions in 1.7, 3.4, 5.0 & 10kW. The new DC series features two types of product lines: fixed range and autoranging.

The autoranging supplies feature expanded current and voltage range at the full output power level, enabling the ability to satisfy a wider testing need without requiring the purchase of additional models.. Its groundbreaking capabilities set the standard for affordable, precision power supplies.
 

The Sorensen™ Asterion® DC ASM Series is the newest addition to the Asterion platform of power testing solutions. The new ASM Series features up to three independent, isolated, fixed-range outputs in a 1U high chassis.

The Asterion DC ASM Series, just like the Asterion DC Series, offers complete remote programming and control via Virtual Panels™ GUI, and intuitive front panel touch screen operation. Additionally, the instrument can be controlled via standard LXI Ethernet, USB, and RS232 control interfaces, as well as through the optional GPIB control interface or isolated analog programming.

Traditional DC Electronic Load Solutions are bulky and large in size. Most are offered with standard voltage, current and power ratings. In the automated test equipment (ATE) world, rack space is a highly coveted asset and application demands are constantly diversifying with new technology development.

AMETEK Programmable Power's PLW Series of “water-cooled” DC Electronic eLoads are capable of being custom-tailored to meet your specific application requirements. The PLW Series also offers a unique condensation protection design, the highest power density and current rating, as well as the widest selection of high-voltage models on the market.

A spacecraft solar array is subjected to large temperature excursions, varying insolation (the amount of sunlight falling on the array), mechanical changes and aging, which substantially effect both its short and long term performance. In order to test the spacecraft's power environment, a cost-effective solution for ground based testing is to utilize a solar array simulator.

The Elgar SAS system reproduces all possible solar array outputs, based on the wide variety of input conditions that an array faces, including orbital rotation, spin, axis alignment, eclipse events, beginning-of-life and end-of-life operation. The SAS also provides complete programmable control of all the parameters that shape the solar cell I/V output curve. By being able to accurately simulate solar panels under various space conditions with complete control, a system developer can comprehensively verify design margins and quickly test, in production, spacecraft power systems and their associated electronics.

Each Solar Array Simulator is a fully integrated, turn-key system complete with Windows NT graphical user interface and hardware control software. It can be remotely controlled and addressable as a single device when integrated into a customer's test system. This control is accomplished via a standard ethernet or optional GPIB interface using standard SCPI format commands.

As a very important consideration in spacecraft testing, discrete hardware protection systems are a standard part of every SAS. These include subsystems that can remove power at the output of the SAS in under 10 microseconds. Each SAS string has an electronic circuit breaker and relay disconnect, so faults are localized and minimize disruption of the last process. SAS systems have been designed and delivered ranging from desktop, 2 channel, R&D units to systems capable of controlling two 64 channel SAS systems simultaneously. AMETEK's Engineered Solutions Group can assist in defining special requirements and customize each system using a standard building block approach. This allows each customer to get exactly what id needed while minimizing costs.

The Elgar Battery String Simulators (BSS) provide safe, reliable battery power for spacecraft testing. The broad range of features available ensures simulation capabilities for more than just two terminal power. It's the ideal solution for complete integrated system testing, not just battery elimination.

The BSS behavior is determined by a charge table, in spreadsheet format, specific for a battery topology and various battery conditions. Many charge tables can be stored on the computer hard drive for easy retrieval.

The BSS operates in two modes, static and dynamic. In the static mode, when a state-of-charge value is entered, the BSS will instantly produce the terminal voltage corresponding to that state-of-charge. Because of this programmable flexibility, time consuming discharge cycles of flight test batteries are eliminated. In the dynamic mode, once a state-of- charge start point is entered, the BSS will monitor the charge and discharge energies being impressed on the "battery" and modify the terminal voltage accordingly.

Single or dual battery pack simulator versions are available with discharge currents of up to 150A and charge currents of up to 50A per battery. In addition, optional sensor simulators (including thermistor, pressure transducer, and heater loads outputs) allow closed loop input to the Spacecraft Power Regulator for true battery emulation. As with the SAS systems, each Battery Simulator System is a fully integrated, turn-key system using a Windows Graphical User Interface and hardware control software. This control is accomplished via a standard ethernet or optional GPIB interface using standard SCPI format commands.

The CSW Series represents a new generation of AC/DC power sources that address the increasing demands on test equipment to perform additional functions at a lower cost. By combining a flexible AC/DC power source with a high performance power analyzer, the Compact CSW Series is capable of handling complex applications that have traditionally required multiple systems. The sleek integrated approach of the CSW avoids cable clutter that is commonly found in test systems. All connections are made internally and the need for digital multimeters, power harmonics analyzers, and current shunts or clamps is eliminated.

Since many components in the CSW are shared between the AC/DC source and the power analyzer, the total cost of the integrated system is less than the typical cost of a multiple unit system.

Easy to use controls
The CSW Series is DSP controlled and can be operated from an easy to use front panel keypad. Functions are grouped logically and are directly accessible from the keypad. This eliminates the need to search through various levels of menus and/or soft keys. A large analog control knob can be used to quickly slew output parameters. This knob is controlled by a dynamic rate change algorithm that combines the benefits of precise control over small parameter changes with quick sweeps through the entire range.

AC, DC or AC+DC Output
A direct coupled, transformerless design allows AC and DC on separate phases or on the same phase. The CSW can be used as a true DC power supply. High DC content waveforms (up to 312 volts) can be created with no derating of output power, even with 100% reactive loads, eliminating the need for a separate DC supply. Waveform programming is easily accomplished using the Graphical Users Interface software. Waveforms can be uploaded and modified from a digital scope. The waveforms can then be downloaded to the CSW and output to precisely simulate real-world conditions.

Easy To Use Local Controls
The CSW Series is DSP controlled and can be operated from an easy to use front panel keypad. Functions are grouped logically and are directly accessible from the keypad. This eliminates the need to search through various levels of menus and/or soft keys. A large analog control knob can be used to quickly slew output parameters. This knob is controlled by a dynamic rate change algorithm that combines the benefits of precise control over small parameter changes with quick sweeps through the entire range.

Flexibility in Power Ranges
The CSW Series is based on a 5,550VA power source. The CSW features selectable Single or Three Phase output via front panel menu selection or via remote control interface. Utilizing Master / Auxilary arrangement the CSW offers the flexibility to paralled up to power levels of 33,300VA

High Crest Factor
With a crest factor of up to 3.25:1; the CSW Series AC source can drive difficult nonlinear loads with ease. Since many modern products use switching power supplies, they have a tendency to pull high repetitive peak currents. The CSW5550 can deliver up to 38.5 Amps of repetitive peak current

Harmonic Waveform Generation
Using the latest DSP technology, the CSW Series programmable controller is capable of generating harmonic waveforms to test for harmonics susceptibility. The Windows Graphical User Interface program can be used to define harmonic waveforms by specifying amplitude and phase for up to 50 harmonics. The waveform data points are generated and downloaded by the GUI to the AC source through the remote interface. Up to 200 waveforms can be stored in nonvolatile memory and given a user defined name for easy recall.

The Sorensen DLM 600 series of programmable power supplies is designed to provide continuously variable output voltage and current for a broad range of applications in a compact 1U (1.75 inches) high, half-rack (8.5 inch) wide chassis.

With the use of Zero Voltage Switching (ZVS) technology, these supplies are able to achieve exceptionally low ripple and noise rivaling larger and more expensive linear power supplies. In addition, the high efficiency and fast load transient response assure that the DLM 600 is ideal for even the most demanding applications.

The DLM 600 power supply series is ideal for high density multiple output rackmount requirements or low profile benchtop applications. Output voltages from 0-5VDC to 0-300VDC and currents from 0-2A to 0-75A are available.

The cooling air intake is at the front and sides with exhaust at the rear and sides. Variable speed fans are controlled as a function of ambient air temperature and load, thus reducing acoustic noise and increasing fan life. This allows supplies to be stacked one directly on top of another without space in between, yielding maximum rackmount packing density and a wide operating temperature of 0-50° C. An optional rackmount kit is available to easily mount one or two units side-by-side.

The front panel layout makes the DLM 600 power supply series easy to use. Voltage and current can be set from individual 10-turn potentiometer knobs. Control push buttons include power on, output on, local/remote, voltage/current preview and overvoltage protection preview. Set-point or actual voltage/ current values can be viewed on two 3-1/2 digit LED displays.

DLM 600 near-linear DC power supplies can be connected in series or parallel. All models automatically accept any standard single phase input without manual set up.
