FAA TSO-C71 REGULATED DC TO DC CONVERTER LIGHT DIMMER
The LT-SERIES is a pulse width-modulated DC to DC converter that provides regulated DC power. This converter transforms an unregulated 28 VDC to a regulated and adjustable DC voltage output via a remote control potentiometer.
The LT-SERIES is primarily designed to control the light intensity of incandescent bulbs in aircraft lighting. The LT-52A, LT-70 and LT-100 converters are FAA TSO-C71 recognized for airborne applications.
LT-52A, LT-70, LT-100
