EA-PSBE 11500-20 3U Programmable Bidirectional DC Power Supply

The EA-PSBE 11500-20 3U is a high-performance programmable bidirectional DC power supply from the EA-PSBE 10000 series, engineered for two-quadrant operation as both a power source and a regenerative electronic load. Featuring advanced autoranging technology, it delivers 0-1500V, 0-20A, and up to 15000W of power, achieving up to 95.5% efficiency in source and sink modes. The device incorporates active Power Factor Correction (PFC) >0.99, accepts 3-phase AC inputs from 208V to 480V (±10%), and includes galvanically isolated USB, Ethernet, and analog interfaces for seamless integration. It delivers stable output with ≤400 mV RMS ripple (300 kHz BW) and ≤2400 mV peak-to-peak noise (20 MHz BW). Load regulation is ≤0.05% FS for CV and ≤0.1% FS for CC, with display accuracy of ≤0.05% FS for voltage and ≤0.1% FS for current. Protection features include adjustable OVP, OCP, OPP, and OTP. The PSBE 11500-20 supports master-slave parallel operation of up to 64 units, enabling scalable system power up to 1920 kW. It is ideally suited for battery testing, battery simulation, fuel cell testing, on-board charger testing, EOL tests, and SOH checks, significantly reducing energy costs and heat generation through regenerative grid feeding.
