LT-101A-BP-31
REGULATED 28/14VDC TO DC POWER CONVERTER
FAA TSO-C71
The LT-71/ LT-101 Series is a pulse width-modulated DC to DC converter that provides regulated power.
The converter transforms an unregulated 28 VDC to a regulated and fixed DC output.
The Model LT-71/ LT-101 Series is primarily designed to supply regulated fixed DC voltage to critical communication, navigation and digital equipment.
Features:
- State of the art design for regulation and positive logic for output overvoltage protection.
- Other voltage control range is available.
- The Model LT-SERIES is serviceable, small and lightweight (33 watts per pound and 1.7 watts per cubic inch).
- Designed to meet various applicable portions MIL-STD 704 notice 3, MIL-STD-202 and MIL-T-5422F class 1A.
