EA-PSB 10500-10 2U Programmable Bidirectional DC Power Supply

The EA-PSB 10500-10 2U is a high-precision, 1500W programmable bidirectional DC power supply and electronic load in a compact 2U rack-mount form factor. As part of the EA-PSB 10000 series, it delivers a wide output range of 0-500V and 0-10A, making it a versatile 500V Programmable Power Supply and a 10A DC Power Supply. Its defining feature is bidirectional operation, functioning seamlessly as both a source (providing clean DC power) and a sink (acting as a regenerative electronic load that feeds energy back to the grid with up to 95% efficiency). It offers exceptional accuracy with voltage regulation ≤0.05% FS and current regulation ≤0.1% FS, alongside fast dynamic response with 10ms current and 20ms voltage rise/fall times. With low output ripple (40mV RMS, 500mV pp) and comprehensive protection features (OVP, OCP, OPP, OT), it is an ideal bench and system power solution for R&D, production test, and applications like battery testing, fuel cell simulation, and solar inverter evaluation.
