EA-PSBE 10080-510 3U 15kW Programmable Bidirectional DC Power Supply

The EA-PSBE 10080-510 3U is a high-performance programmable bidirectional DC power supply from the EA Elektro Automatik PSBE 10000 Series. This 3U form factor unit combines the functions of a DC power supply and a regenerative electronic load in a single device, operating as a two-quadrant power supply with energy recovery to the grid. With an 80V output voltage, 510A output current, and 15000W output power, it delivers flexible power through autoranging technology, maintaining constant power characteristic across a wide operating range. Ideal for applications such as battery test equipment, battery simulation, fuel cell test systems, on-board charger testing, and battery recycling, this programmable DC power supply reduces energy costs by feeding back energy with up to 94.5% efficiency, minimizing heat generation and lowering air conditioning requirements. It features built-in USB and Ethernet interfaces, analog programming, and supports master-slave parallel operation with share bus for scalable systems up to 64 units, making it a top choice for automated test systems, EOL testing, and State of Health (SOH) checks. The device includes adjustable overvoltage, overcurrent, and overpower protection, ensuring reliable operation in demanding environments. With low ripple of ≤10 mV RMS (300 kHz bandwidth) and ≤100 mV p-p (20 MHz bandwidth), it provides clean and stable DC output for sensitive testing. The 3U chassis integrates a 5" TFT touch display for intuitive control, and the unit is equipped with galvanically isolated interfaces including USB, Ethernet, and analog I/O (0-5V/0-10V switchable). Optional fieldbus interfaces such as CAN, Profibus, and EtherCAT are available via plug-in slots, enabling seamless integration into automated test systems. The PSBE 10080-510 3U also features a wide AC input range of 208-480V ±10% 3-phase with active PFC (>0.99), making it suitable for global mains voltages. Its regenerative capability not only reduces energy costs but also decreases investment cost by combining power supply and load functions in one unit, while minimizing heat generation and lowering air conditioning expenses. Whether used for computer power supply testing, as a benchtop power supply, or in high-power industrial systems, this programmable power supply delivers exceptional performance and scalability.
