Description
The LT-3xx series is a pulse width-modulated DC to DC converters that provides regulated multiple output power. The converter transforms unregulated 28 VDC to regulated DC output that is adjustable via a remote control potentiometer or voltage control models. The LT-3xx series is designed to control light intensity of incandescent bulbs in lighting systems.
Features
- State of the art design for regulation and positive logic for output over voltage protection
- Maximum output voltage 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 IA
- LT-3xx series is serviceable, small, and lightweight
- Special orders any three combinations of LT-52A, LT-53, LT-70, LT-73, LT-100 and LT-103 can be supplied
