LT-3103-4 Regulated DC to DC Power Converter | 28 VDC Input, 0–5 VDC Output
Product Description
The LT-3103-4 is a pulse width-modulated DC to DC converter that provides regulated multiple output power. The converter transforms an unregulated 28 VDC to a regulated and adjustable DC output via a remote control potentiometer or voltage for voltage controlled models. The LT-3103-4 is primarily designed to control the 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.
- The Model LT-3103-4 is serviceable, small and lightweight (42 watts per pound and 1.7 watts per cubic inch)
