DC POWER CONVERTER/DC to regulated and controllable DC power converter, 75-120 watt. 300 ohm to 10K 1/2W potentiometer.
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.
