EA-PSB 10360-30 2U 360V 30A 3000W Programmable Bidirectional DC Power Supply

The EA-PSB 10360-30 2U is a high-precision, programmable bidirectional DC power supply that integrates the functions of a laboratory power source and an electronic load into a single 2U rack-mount unit. As part of the PSB 10000 series, this model delivers 0-360V, 0-30A, and up to 3000W of power. It features seamless sink-source mode switching and energy recuperation, feeding up to 95% of absorbed DC energy back to the AC grid. With a voltage accuracy of ≤0.05% FS and current accuracy of ≤0.1% FS, along with fast 10ms current and 20ms voltage rise/fall times, it ensures reliable performance for testing applications. The unit includes a color TFT touchscreen, built-in function generator (sine, triangle, arbitrary, PV/FC simulation, battery test, MPP tracking), and extensive interfaces (analog, USB, Ethernet, optional digital modules). It supports master-slave parallel operation for up to 64 units, making it ideal for R&D, production test, and advanced applications like battery testing and solar inverter characterization.
