The LT-46C 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 fixed. Adjustable output current and voltage models are also available.

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


  • State of the art design for regulation and positive logic for output overvoltage protection (PWM control topology).
  • The LT-46C is 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.
