EA-PSB 11500-60 4U Bidirectional Programmable DC Power Supply

The EA-PSB 11500-60 4U is a high-performance, programmable bench power supply that integrates a precision 30 kW DC power source and an electronic load into a single 4U rack-mount unit. As a key model in the EA-PSB 10000 series, it delivers 0-1500V and 0-60A, functioning seamlessly as both a programmable DC power supply (source) and a TPS electronic load (sink). Its defining feature is the energy recovery system, which recuperates up to 96.5% of absorbed DC energy and feeds it back into the AC grid, making it an efficient and cost-effective solution for high-power testing. Equipped with a 5-inch color touchscreen, integrated function generator for waveforms (sine, triangle, rectangle, etc.), and specialized modes for photovoltaic simulation, battery test, and MPP tracking, it is an ideal, top-budget PSU for R&D, qualification, and production testing of components like EV batteries, power converters, and solar inverters.
