EA Bidirectional DC Power Supplies

Programmable power supply & regenerative load all in one

The EA-PSB Series bidirectional DC programmable power supply with integrated, regenerative electronic load series provides 15kW in 3U or 30kW in 4U chassis with up to 2000 VDC. This high power series easily parallels supplies up to 1.92MW of racked power. All EA Elektro-Automatik DC power supplies and loads feature true autoranging to cover a wider operating range of voltage and current, while still maintaining full output. This means that a much wider range of test routines can be addressed with a single EA bidirectional DC power supply with autoranging.

The bidirectional PSB has a built-in regenerative load that boasts 96% energy recovery saving operating costs and almost entirely reducing energy dissipated as heat, making the PSB budget friendly as well as environmentally friendly.

The PSB series bidirectional DC power supply features 5″ TFT Gorilla® Glass touchscreen display for intuitive control and programming. The intelligent interface allows you to configure and test quickly. EA bidirectional dc power supplies come standard with an arbitrary waveform function generator, swappable digital interface module and built-in test routines for battery test, fuel cell simulation, photovoltaic simulation with MPP tracking, and more.
