Product Description

The LT-253-400 series pulse-width modulated AC to DC converters provide regulated DC power from an unregulated 115 VAC, 400 Hz power source. The DC output can be adjusted via remote control potentiometer or voltage for voltage controlled models. these power converters are primarily designed to control incandescent lights in aircraft lighting systems.
