LT55A Converter DC to DC
(KGS products can only be shipped to U.S. address only.)
(DAI Part# LT55A)
LT-55 ( ) and LT-57 ( ) series are pulse width-modulated DC to DC converters that provide regulated high power DC
Converter transforms an unregulated 28VDC to a regulated fixed or adjustable DC output via a remote control potentiometer
LT-55 ( ) series is primarily designed to control the light intensity of incandescent bulbs in aircraft instrument lighting when requiring 0-15 AMPS at 5VDC output
Model LT-57 ( ) series is designed for 0-10 AMPS up to 13.75VDC output
