  • Please allow for an extra 7-10 days for International orders to process, especially orders including HazMat items, or items that are not in stock in our NY Warehouse.
  • International Orders Ship Complete: You get one package shipped which reduces added taxes and duties that may be incurred from multiple shipments.
    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. Fixed output and voltage control models are also available.

    The LT-48 is primarily designed to control the light intensity of incandescent bulbs in aircraft lighting. The LT-48 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-48 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.
