EA-PSBE 10500-60 3U 10000W Programmable Bidirectional DC Power Supply

The EA-PSBE 10500-60 3U is a high-performance programmable bidirectional DC power supply from the EA-PSBE 10000 3U series by EA Elektro-Automatik. This 10kW regenerative two-quadrant device combines the functionality of a DC power supply and an electronic load in a single 3U form factor, capable of both sourcing and sinking power with seamless transition. It delivers a DC output voltage from 0 to 500V and a DC output current from 0 to 60A, maintaining its full 10000W across a wide operating range thanks to its flexible autoranging technology and constant power characteristic. In sink mode, the unit operates regeneratively, feeding energy back into the grid with an efficiency of up to 95.5%, which dramatically reduces energy costs and minimizes heat generation compared to conventional loads, thereby lowering air conditioning requirements and overall investment costs. The device offers high precision with 16-bit digital control and supports multiple regulation modes including CV, CC, CP, and CR. It features a galvanically isolated analog interface (0-5V or 0-10V switchable) and built-in digital interfaces including USB and Ethernet. For system expansion, the integrated Master-Slave bus and Share-Bus enable parallel operation of up to 64 units across the PSBE 10000 series, allowing for scalable high-power systems with equal load distribution. With a wide AC input range of 208V to 480V (±10%) three-phase, active power factor correction (>0.99), and comprehensive protective functions (OVP, OCP, OPP, OTP), the PSBE 10500-60 is ideally suited for automated test systems, battery test and simulation, fuel cell test systems, on-board charger (OBC) testing, EOL (End of Line) tests, State of Health (SOH) checks, and battery recycling applications.

Key Features

• Bidirectional and Regenerative Operation: Functions as a true two-quadrant power supply and electronic load. In sink mode, it recovers energy and feeds it back into the grid with up to 95.5% efficiency, significantly reducing energy costs and eliminating the need for external load banks.
• High Power Density and Autoranging: Delivers 10kW of power in a compact 3U chassis. Autoranging technology provides a wide voltage (0-500V) and current (0-60A) envelope, maintaining full power across a broad operating range for maximum test flexibility.
• Precision and Low Ripple: Ensures accurate testing with high display accuracy (voltage ≤0.05% FS, current ≤0.1% FS) and low output ripple (≤70 mV rms, ≤350 mV p-p), guaranteeing reliable and reproducible results.
• Comprehensive Connectivity and Scalability: Built-in USB, Ethernet, and galvanically isolated analog interfaces. Master-Slave bus allows parallel operation of up to 64 units for systems up to 1920kW, with Share-Bus ensuring balanced current sharing.
• Wide AC Input and Grid-Friendly: Operates on global three-phase mains from 208V to 480V (±10%) with active power factor correction (typical 0.99), automatically adapting to the available supply.
• Advanced Protection and Control: Features adjustable overvoltage (OVP), overcurrent (OCP), overpower (OPP), and overtemperature (OTP) protection, along with selectable control speeds (Normal, Fast, Slow) to match DUT characteristics.
