Keysight RP5933A Regenerative DC Power Supply

Overview

The Keysight RP5933A is a compact regenerative DC power supply in a 1U form factor, designed for high-power testing in laboratory and production environments. With 0-80V/±120A output (6kW maximum), bidirectional operation, and integrated electronic load, it efficiently returns up to 95% of absorbed energy back to the grid, reducing cooling and operational costs.

Key Features

• Output range: 0 to 80V, 0 to ±120A, 0 to 6kW
• Regenerative operation with up to 95% energy recovery to AC mains
• Bidirectional source/load with 100% current sinking capability
• Battery emulation with adjustable voltage, capacity, internal resistance, and State of Charge
• Waveform generation for voltage and current transients (step, arbitrary, list modes)
• Multiple operating modes: Constant Voltage, Constant Current, Constant Resistance, Constant Power
• Built-in voltage and current measurements with 3-inch LCD display
• Standard interfaces: Ethernet/LAN, USB 2.0, CAN (optional GPIB, analog, RS-232)
• Supports paralleling of up to 16 units for system configurations up to 192 kW
• AC input: 380-480 VAC, 50/60 Hz, three-phase

Applications

• Battery testing and performance characterization under realistic power conditions
• Device validation under power transient simulation
• High-power system test and ATE applications
• Multi-unit configurations for enhanced power delivery
