Pulse width-modulated DC to DC converter that provides regulated DC power
Transforms an unregulated 28 VDC to a regulated and adjustable DC voltage output via a remote control potentiometer
Primarily designed to control the light intensity of incandescent bulbs in aircraft lighting
State of the art design for regulation and positive logic for output overvoltage protection
Small and lightweight
Maximum output voltage is adjustable with an internal trim pot
Designed to meet various applicable portions MIL-STD 704 notice 3, MIL-STD-202C and MIL-T-5422F class 1A
Control circuitry includes use of PWM integrated circuit for voltage regulation and overload current limit
Protection circuitry includes a low/high input voltage shutdown, low/high output frequency shutdown, output overvoltage limit, and output short circuit current limit
Fault monitor circuitry includes fault indication upon high/low input voltage, high/low output voltage and high/low output frequency conditions
