EA-PSBE 10750-20 3U Programmable DC Power Supply

The EA-PSBE 10750-20 3U is a high-performance programmable DC power supply from the EA-PSBE 10000 3U series, delivering 5000 W of output power in a compact 3U form factor. Designed for precision and reliability, this unit offers an output voltage range of 0-750 V and a current range of 0-20 A, making it ideal for automated test equipment (ATE), laboratory experiments, industrial automation, and production line testing. It features low output ripple: ≤200 mV rms (300 kHz bandwidth) and ≤800 mV p-p (20 MHz bandwidth), ensuring clean and stable power for sensitive electronic component testing. Display accuracy is ≤0.05% FS for voltage and ≤0.1% FS for current, with load regulation of ≤0.05% FS for CV mode and ≤0.1% FS for CC mode. The device accepts a wide three-phase AC input from 208 V to 480 V ±10% (with derating at 208 V), includes active PFC (typical 0.99), and operates at 45-66 Hz. It supports multiple regulation modes: CV, CC, CP, and CR with fast crossover, and selectable control speed (Normal, Fast, Slow) via 16-bit ADCs/DACs. Protections include adjustable OVP (0-110% U_N), OCP (0-110% I_N), OPP (0-110% P_N), and overtemperature shutdown. Built-in galvanically isolated interfaces comprise USB, Ethernet (100 MBit), USB Host for data logging, and a 15-pin D-Sub analog interface (0-5 V/0-10 V programmable). Optional fieldbus modules (CAN, CANopen, RS232, Profibus, EtherCAT, Profinet, Modbus) are available via Plug & Play slot. The Master-Slave bus and Share-Bus allow parallel operation of up to 64 units of any power class in the 10000 series, enabling scalable systems up to 1920 kW. The 5" color TFT touch display with intuitive interface and rotary knobs ensures easy operation. With insulation ratings of ±1500 V DC (negative pole to PE) and +2000 V DC (positive pole to PE), it is suitable for research and development, battery charging and testing, and as a precision voltage and current source for system power supply applications.
