EA-PSBE 10080-170 3U 5kW Programmable Bidirectional DC Power Supply

The EA-PSBE 10080-170 3U is a 5kW programmable bidirectional DC power supply from the PSBE 10000 series by EA Elektro-Automatik, designed for laboratory and industrial applications requiring two-quadrant operation with energy recovery. This regenerative DC power supply seamlessly combines the functions of a programmable DC power supply and a DC electronic load, capable of both sourcing and sinking power with efficient energy feedback to the grid (up to 96% efficiency in load mode). With an autoranging output stage, it delivers a wide operating range: 0-80V voltage, 0-170A current, and 5000W power, maintaining full power across a broad voltage-current curve. Key performance specifications include ultra-low ripple of ≤10mV rms (300kHz BW) and ≤100mV p-p (20MHz BW), fast transient response (CV rise/fall times ≤20ms, CC ≤10ms), and high display accuracy (0.05% FS voltage, 0.1% FS current). The unit features a 5" TFT touch display, digital control with 16-bit ADCs/DACs, and three selectable control speeds (Normal, Fast, Slow) for optimal loop matching. Built-in galvanically isolated interfaces include USB, Ethernet, and a 15-pin analog interface (0-5V/0-10V programmable for U/I/P/R), plus a USB host for data logging. For system expansion, the Master-Slave-Bus and Share-Bus allow parallel connection of up to 64 units across the PSBE 10000 series (same voltage class), scaling power up to 1920kW and current up to 64000A. Typical applications include battery testing (cells, modules, packs), battery simulation, fuel cell test systems, on-board charger (OBC) testing, and battery recycling systems, leveraging its regenerative capability to reduce energy costs and cooling requirements. Compliance with global mains (208-480V ±10% 3ph AC, active PFC >0.99) and comprehensive protections (OVP, OCP, OPP, OTP) ensure reliable operation in diverse environments.
