Product Description

The LT-46D 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. Fixed output and voltage control models are also available.

The LT-46D is primarily designed to control the light intensity of incandescent bulbs in aircraft lighting. The LT-46D are qualified to the FAA technical standards order (TSO-C71) for airborne static DC-DC electrical power converters.

Features

State of the art design for regulation and positive logic for output overvoltage protection (PWM control topology).
Serviceable, small and lightweight.
Maximum output voltage is adjustable with an internal trim pot.
Designed to meet MIL-STD 704 Cat. B, MIL-STD-810C and MIL-STD-461A.
