EA-PSBE 10200-140 3U 10kW Programmable Bidirectional DC Power Supply

The EA-PSBE 10200-140 3U is a high-performance programmable bidirectional DC power supply from the EA Elektro Automatik PSBE 10000 Series. This 3U form factor unit integrates the functions of a DC power supply and a regenerative electronic load, operating as a two-quadrant power supply with energy recovery to the grid. Delivering 200V output voltage, 140A output current, and 10000W output power, it features autoranging technology for a wide operating range with constant power characteristic, maintaining full power across diverse voltage and current combinations. With low ripple of <40 mV RMS (300 kHz bandwidth) and <300 mV p-p (20 MHz bandwidth), it ensures clean and stable DC output for sensitive applications. The unit achieves up to 94.5% efficiency in regenerative mode, significantly reducing energy costs and minimizing heat generation, thereby lowering air conditioning requirements. Ideal for battery test equipment, battery simulation, fuel cell test systems, on-board charger testing, EOL test end of line, and State of Health check SOH in automated test systems, this programmable power supply includes built-in galvanically isolated USB, Ethernet, and analog interfaces (0-5V/0-10V switchable) with remote sense compensation up to 5% of nominal voltage. Optional fieldbus interfaces like CAN, Profibus, and EtherCAT are available via plug-in slots. The device supports master-slave parallel operation with share bus for up to 64 units, enabling scalable systems up to 1920 kW with equal load sharing. Comprehensive protection features include adjustable OVP (0-110%), OCP (0-110%), OPP (0-110%), and overtemperature shutdown. The 5" TFT touch display and rotary knobs provide intuitive local control, while SCPI, ModBus, LabVIEW, and IVI drivers facilitate remote integration. With a wide AC input range of 208-480V ±10% 3-phase and active PFC (>0.99), it adapts automatically to global mains voltages, making it a versatile solution for reducing investment costs and energy consumption in industrial and laboratory environments.
