1250B PROGRAMMABLE POSITION MONITOR

The 1250B is a versatile programmable position monitor. Its main application is for Transformer LTC position monitoring, but its non-linear conversion table gives it the ability to convert non-linear rotary motion into a linear scale for additional applications.

TRANSMITTER RETROFIT KIT

Provides easy Synchro Transmitter retrofit to voltage regulators.

• The 1265 does NOT include lightening / surge protection. If needed, MOV protection should be installed in a nearby junction box.

Highlights

• Some Load Tap Changers and Voltage Regulators can not be equipped with Selsyn® synchro transmitters. This problem can be easily solved with the INCON model 1265 Transmitter Retrofit Kit.
• For those applications where there is no easy way to retrofit a transmitter to the LTC drive mechanism, INCON offers the Model 1265 Transmitter Retrofit Kit.
• The 1265 retrofit kit replaces the glass lens on the local indicator dial.
• The 1265 is designed for use with the INCON model 1250B Programmable Position Monitor, which displays the LTC position and can transmit a proportional analog signal to SCADA.
• The Kit comes complete with a Synchro, mounted on a clear Lexan Dial and a two-pronged engagement arm that tracks the position of the Dial Indicator needle.
• The Kit also includes the mating connector pieces, to facilitate assembly of a field wiring cable, although it is recommended that the factory-assembled cable be used.
• Provides accurate Tap Position Status in remote locations.
• Proven reliability with many in Utility & Industrial operations for over 20 years.
• Does not interfere with mechanical draghand operation.
• Highly reliable and accurate (1292) synchro transmitter is included.
• Saves manual reporting time and money.
• Maintenance free.
• Can be retrofited to older LTC’s without existing synchros.

POWER SUPPLY

An adjustable 12 to 15 Volt DC regulated Power Supply that is used to provide loop power for INCON Panel Meters ordered with the 4 to 20 milliamp analog output option.

• This product is a Class 1 power supply and requires the chassis to be connected to earth ground at end application. Use 700 °C iron for soldering input connections. Tolerance for 230 VAC operations is +15% to -10%.

Highlights

• VDE transformer construction (full rated to 50 °C)
• + 0.05% regulation - Foldback/current limit
• T.C. burned-in to MIL - 883 Lev. B
• UL recognized/CSA certified
• Chassis notched for AC input
• 100/120/220/230-240 VAC power
• Industry standard frame size

Applications

• The 1945 power supply has inherently low conducted and radiated noise levels for most system applications that meet the requirements of FCC Docket 20780 for Class A equipment and VDE 0871 for Class A equipment without additional noise filtering.
• Convection cooling is adequate where non-restricted airflow is available. When operating in a confined area, moving air or conduction cooling is recommended.
• The five-wire input to the 1945 provides four voltage ranges: 100/ 120/220/230-240. Extended low line tolerance provides additional drop out margin in areas where line voltages are marginal. Inputs must be fused.

Safety

The 1945 power supply is designed to meet or exceed requirements of the following specifications: IEC 380, IEC 435, VDE 0730 Part 2, VDE 0804, ECMA-57, CEE 10 Part 2P, UL 1012, CSA 22.2 No. 143, CSA 22.2 No. 154.
