EA-PSBE 10060-1000 4U Programmable Bidirectional DC Power Supply & Electronic Load

The EA-PSBE 10060-1000 4U is a high-performance, 30 kW bidirectional DC power supply and regenerative electronic load, delivering exceptional flexibility for advanced testing applications. This unit operates as both a precise source (power supply) and a regenerative sink (electronic load), feeding up to 96% of absorbed energy back into the AC grid for remarkable efficiency and cost savings. It features a wide 0-60V / 0-1000A output (autoranging) with high precision (CV load regulation ≤0.05% FS, display accuracy: voltage ≤0.05% FS, current ≤0.1% FS) and supports all standard regulation modes: Constant Voltage (CV), Constant Current (CC), Constant Power (CP), and Constant Resistance (CR). Control is intuitive via a 5-inch color TFT touchscreen and two programmable knobs, with extensive remote operation through built-in USB, Ethernet (100 MBit), and an isolated analog interface (0-5V/0-10V). For system scaling, integrated Share BUS and digital Master-Slave bus (RS485) enable parallel connection of up to 64 units, creating a synchronized high-power system up to 1920 kW. The device accepts a wide three-phase AC input (208V to 480V ±10%, with auto-derating to 18 kW at 208V) and is available in standard air-cooled or optional water-cooled (WC) versions. Ideal for battery simulation, fuel cell testing, on-board charger (OBC) validation, and battery recycling analysis, the EA-PSBE 10060-1000 4U combines power, precision, and energy regeneration in a robust 4U rack-mount design.
