EA-PSBE 11000-80 4U 30 kW Bidirectional High-Voltage DC Power Supply

The EA-PSBE 11000-80 4U is a versatile, high-power bidirectional DC power supply and electronic load in a compact 4U rack-mount chassis. It delivers a full 30 kW with an autoranging output capable of 0 - 1000 V and 0 - 80 A, making it an ideal single-unit solution for testing a wide range of high-voltage components and systems. Its regenerative design feeds up to 95.8% of absorbed energy back into the grid with an overall efficiency of up to 96%, dramatically cutting energy costs and eliminating the need for bulky, heat-dissipating loads. The unit supports CV, CC, CP, and CR regulation modes with fast crossover for precise control. Featuring a 5-inch color TFT touchscreen, built-in USB and Ethernet interfaces, and an isolated analog interface (DB15) for remote control. Integrated Master-Slave and Share buses enable seamless parallel operation of up to 64 units, creating scalable systems up to 1920 kW. Designed with safety for high-voltage applications, it offers robust insulation between output and protective earth.
