INCON 1511 LTC

INCON 1511 LTC

The 1511-LTC provides basic LTC tap position monitoring using the LTC’s slide wire position feedback device. As the LTC changes taps, the moveable contact picks up the voltage divided through the resistors in the slide wire, so that each tap has its own specific voltage.

SMART DISTRIBUTION TRANSFORMER MANAGEMENT

The range of INCON® Load Tap Changer (LTC) Position Monitors relay critical position information between the LTC and the LTC controller, enabling distribution transformers to run as efficiently as possible.

ACCESSORIES

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.

Model Description
1945 15 VDC Loop Power Supply (For 4-20 mA Analog Output)
  • 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. 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.
