The LT-55A is a pulse width-modulated DC to DC converter that provides regulated high power DC.
This converter transforms an unregulated 28 VDC to a regulated fixed or adjustable DC output via a remote control potentiometer.
The LT-55A is primarily designed to control the light intensity of incandescent bulbs in aircraft instrument lighting when requiring 0-15 amperes at 5 VDC output.
- State of the art design for regulation and positive logic for output overvoltage protection.
- Maximum output voltage is adjustable with an internal trim pot.
- Maximum current limit is adjustable with an internal trim pot.
- Designed to meet various applicable portions MIL-STD 704 notice 3, MIL-STD-202 and MIL-T-5422F class 1A.
