511-LTC PROGRAMMABLE POSITION MONITOR
The 1511-LTC provides basic LTC tap position monitoring using the LTC’s existing position feedback device. Slidewire voltage measurements are filtered by firmware to give a stable, reliable tap position reading. Simple to install and easily calibrated to any LTC Slidewire.

Description |
| 1945 |
15 VDC Loop Power Supply (For 4-20 mA Analog Output) |
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. Specifically, field terminal to terminal spacing is 5.25 mm with 9.0 mm creepage to other metal. Leakage current is less than 5.0 mA and dielectric withstanding voltages are 3750 VAC input to chassis. 3750 VAC input to output and 300 VDC output to chassis.
