The Danaher Motion / Kollmorgen PSR4/5-220 is a 6.0 kW regulated DC power supply module engineered for industrial servo drive systems. It converts single-phase or three-phase AC input to a 310 VDC main bus, supplying stable power to amplifier modules while managing regenerative energy through an integrated shunt regulator. The module features soft-start current limiting, independent control bus circuitry, and regeneration protection—making it suitable for motion control systems requiring reliable power conversion under demanding industrial conditions.
