LT100 Converter DC to DC
(KGS products can only be shipped to U.S. address only.)
(DAI Part# LT100)
LT-series is a pulse width-modulated DC to DC converter that provides regulated power
Converter transforms an unregulated 28VDC to a regulated and adjustable DC output via a remote control potentiometer
LT-series is primarily designed to control the light intensity of incandescent bulbs in aircraft lighting
LT-52A and LT-100 converters are FAA PMA recognized

State of the art design for regulation and positive logic for output over voltage protection
Other LT-series available in various output voltages and power ratings in the same package size
LT-series is serviceable, small and lightweight
Maximum output voltage is adjustable with an internal trim pot
Designed to meet various applicable portions MIL-STD 704 notice 3, MIL-STD-202C and MIL-T-5422F class 1A
