OS Series - High Voltage Power Supply

The OS family of power supplies are sophisticated 2 kW, open stack, power supplies with extremely low ripple and noise. They are air insulated fast response units with tight regulation. They are designed to meet the growing demands from both users and electric utilities for switching supplies with excellent input power factors that draw harmonic currents below those specified in EN61000-3-2.
