EA-PSBE 10200-70 3U 5000W Programmable Bidirectional DC Power Supply

The EA-PSBE 10200-70 3U is a compact, high-performance programmable bidirectional DC power supply from the EA-PSBE 10000 3U series, designed for two‑quadrant operation as both a DC source and a regenerative electronic load. It delivers a flexible output range of 0‑200 V and 0‑70 A, with a total power of 5000 W. Utilizing advanced autoranging technology, the unit maintains full power across a wide voltage and current envelope, offering greater application flexibility than traditional power supplies. In sink mode, it recovers energy back to the grid with an impressive efficiency of up to 94.5%, significantly reducing energy costs and minimizing heat dissipation. Key specifications include low output ripple (<40 mV RMS, 300 kHz BW; <300 mV p‑p, 20 MHz BW), a minimum voltage for full sink current of <2.0 V, and a resistance simulation range of 0.1 Ω to 160 Ω. The device features digital control with 16‑bit ADCs/DACs, a fast crossover between CV/CC/CP/CR modes, and a 5″ colour TFT touch display for intuitive operation. Built‑in galvanically isolated interfaces include USB, Ethernet, USB host, and a 15‑pole analog D‑Sub (0‑5/10 V). Optional fieldbus interfaces (CAN, CANopen, Profibus, EtherCAT, Profinet, Modbus) are available via plug‑in slots. For system expansion, the Master‑Slave and Share‑Bus allow parallel operation of up to 64 units, reaching system powers up to 1920 kW. This model (article no. 30000755) is ideally suited for laboratory automation, battery testing and simulation, fuel cell testing, on‑board charger testing, and educational applications, combining precise performance, reliability, and sustainable energy recovery in a 3U form factor.
