EA-PSBE 11500-60 4U 30 kW Bidirectional High-Voltage DC Power Supply

The EA-PSBE 11500-60 4U is a high-voltage, programmable bidirectional DC power supply and electronic load in a 4U rack-mount form factor, delivering a full 30 kW of power. It features an autoranging output with an extended voltage range of 0 - 1500 V and a current range of 0 - 60 A, making it ideal for testing high-voltage energy storage systems, power electronics, and electric vehicle components. As a regenerative system, it recovers energy back to the grid with an efficiency of up to 96.5%, drastically reducing operational costs and thermal management requirements. The unit supports CV, CC, CP, and CR regulation modes with fast crossover. It is equipped with a 5-inch color TFT touchscreen, built-in USB and Ethernet interfaces, and an isolated analog interface (DB15). Integrated Master-Slave and Share buses enable the parallel operation of up to 64 units for scalable systems up to 1920 kW. Its high-voltage capability is complemented by reinforced insulation, with the positive DC pole isolated at +2000 V DC relative to protective earth (PE).
