AC 1000W Power Supply

Espey developed this power supply for a major locomotive manufacturer. The high reliability power converter was designed and tested for extreme locomotive environmental conditions. This power supply converts the 25-85 VDC locomotive battery to a dual regulated 100 VAC, 25 kHz square waves with a power rating of 1300 W for each output. These outputs drive multiple, distributed loads consisting of isolated, high power gate drivers for 1000 HP three phase motors.
