EA-PSBE 12000-40 4U 30 kW Bidirectional Ultra-High-Voltage DC Power Supply

The EA-PSBE 12000-40 4U stands at the top of the series as an ultra-high-voltage, programmable bidirectional DC power supply and regenerative electronic load. Delivering a full 30 kW, it offers the widest voltage range in the 4U class, from 0 to 2000 V, with a current output of 0 - 40 A. This makes it the premier choice for testing the most demanding high-voltage applications, such as next-generation electric vehicle powertrains, large-scale energy storage systems, and industrial power converters. Its regenerative design recovers energy with up to 96.5% efficiency, feeding it back to the grid to slash energy costs and eliminate the need for external, heat-producing loads. The unit supports CV, CC, CP, and CR regulation modes and is equipped with a 5-inch color TFT touchscreen, built-in USB and Ethernet, and an isolated analog interface. With integrated Master-Slave and Share buses, up to 64 units can be paralleled for systems up to 1920 kW, all managed as one.
