The PSR Servo Power Supplies series is a family of power supply units designed to provide DC bus power and regenerative energy handling for BDS and ACS servo systems.
The series includes versions for lower- and higher-voltage mains, with input classes based around 115 VAC and 230 VAC operation, support for single-phase or three-phase supply, and frequency compatibility across 47 to 63 Hz. Across the series, output is provided as a DC bus, with listed bus levels of 160 VDC on lower-voltage versions and 325 VDC on higher-voltage versions, while current classes extend from 12 amps per phase up to 75 amps depending on the model. Regeneration capability is a core part of the platform, with configurations that use internal shunt regeneration on selected units and external regeneration resistor arrangements on others, including higher-current versions that rely on external resistor kits. The PSR Servo Power Supplies series is suited for servo installations that require centralized bus power, controlled regenerative braking energy management, and electrical characteristics such as soft-start behavior and short bus charge times.
