Description

The ABB PS203PRESPMCPS is an auxiliary power supply module designed for ABB UNITROL generator excitation systems. This PS203PRESPMCPS converts AC input voltage into several isolated DC supplies for control boards, fiber interfaces and signal conditioning circuits inside excitation cabinets. Built-in protection circuits prevent damage from voltage surges, short-circuits and overload in power station environments.
