DC Power Supply

The OZPCS-RS40-PS is a digitally controlled, bidirectional DC power supply engineered for advanced energy storage, rectification, and AC switch applications. Its seamless bidirectional design allows effortless transition between sourcing and sinking current without user intervention. Offering wide 208-480 VAC and 0–820 VDC ranges, multiple control modes (voltage, current, power), and peak efficiency up to 98.22%, it delivers precision, flexibility, and reliability. The compact 2.5U rack-mount design saves space, while Modbus RS-485 connectivity, software-configurable protections, and Power Studio™ GUI simplify setup, monitoring, and control.
