The LT-48 is a pulse width-modulated DC to DC converter that provides regulated output power. This converter transforms an unregulated 28 VDC to regulated output power. The output voltage is adjusted via a remote control rheostat 5K ohm 1/2 W to ground. The LT-48 is primarily designed to control the light intensity of incandescent bulbs in aircraft lighting. The LT-48 is qualified to the FAA technical standards order (TSO-C71) for airborne static DC-DC electrical power converters.
