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.
Features
- Seamless Bidirectional Power Flow – Automatically sources or sinks current without user configuration, supporting complex testing and energy applications.
- Flexible Control Modes – Voltage, current, and power control modes allow precise system tuning for diverse loads and operating conditions.
- High Efficiency & Power Quality – Achieves 96.92% CEC efficiency and 98.22% peak efficiency with <3% harmonics at rated current for reliable performance.
- Compact & Scalable Design – 2.5U, 19” rack-mount form factor with front-side cable routing; parallelable units enable simple scaling for high-power systems.
- Smart Connectivity & Monitoring – Modbus RS-485 interface and Power Studio™ GUI provide intuitive configuration, real-time control, and data logging.
- Rugged Thermal Management – Variable speed forced-air cooling ensures stable operation in demanding environments while reducing noise and extending life.
- Wide Application Range – Ideal for single- and three-phase rectifiers, independent AC switches, 4-quadrant rectifiers, and renewable integration.
- Built-In Protection Features – Software-configurable safety functions provide reliable system protection tailored to user-specific applications.
