AC TO DC REGULATED POWER CONVERTER
The WH120 DC power supply converts 115/200 VAC, 4 wire Wye, 400 Hz 3 phase input to a regulated 28 VDC up to 1200 watt maximum continuous output.
Design features include off line rectification, a pulse width modulated DC to DC step down voltage conversion and a rugged, high power IGBT power module for reliable and lightweight operation.
The WH120 is designed for the operation of mobile and ground vehicle equipment and lighting systems requiring regulated 28 VDC.
