EA-PSBE 10080-340 3U 10kW Programmable Bidirectional DC Power Supply

The EA-PSBE 10080-340 3U is a 10kW programmable bidirectional DC power supply from the EA Elektro-Automatik PSBE 10000 series, engineered for demanding applications requiring two-quadrant operation with regenerative energy recovery. This bidirectional power supply integrates the capabilities of a programmable DC power supply and a regenerative electronic load, seamlessly sourcing and sinking power while feeding energy back to the grid with up to 94.5% efficiency in load mode—significantly reducing energy costs, minimizing heat generation, and lowering air conditioning requirements. Featuring an autoranging output stage, it delivers a wide operating envelope: 0-80V voltage, 0-340A current, and 10000W power, maintaining full output across an extensive voltage-current curve. Key technical specifications include ultra-low ripple of ≤10mV rms (300kHz BW) and ≤100mV p-p (20MHz BW), fast transient response (CV rise/fall ≤20ms, CC ≤10ms), and high measurement accuracy (0.05% FS voltage, 0.1% FS current). The unit incorporates digital control with 16-bit ADCs/DACs and three selectable control speeds (Normal, Fast, Slow) to optimize loop compatibility with devices under test such as on-board chargers. Built-in galvanically isolated interfaces include USB, Ethernet, a 15-pin analog interface (0-5V/0-10V programmable for U/I/P/R), and a USB host for data logging. For scalable system integration, the Master-Slave-Bus and Share-Bus enable parallel connection of up to 64 units (same voltage class) across the PSBE 10000 series, achieving system powers up to 1920kW and currents up to 64000A. Typical applications span battery test equipment (cells, modules, packs), battery simulators, fuel cell test systems, on-board charger (OBC) testing, EOL (End of Line) testing, State of Health (SOH) checks for battery recycling applications, and automated test systems—leveraging energy recovery to decrease investment and operational costs. The unit operates from a wide-range 3-phase AC input (208-480V ±10%) with active PFC >0.99, and includes comprehensive protective features (OVP, OCP, OPP, OTP) for reliable operation in laboratory and industrial environments.
