ElectroAutomatik PSB Series


The EA-PSB Series bidirectional DC programmable power supply with integrated regenerative electronic load is capable of absorbing current and returning up to 96% of it to the local power grid. This regenerative capability significantly reduces heat, noise, and HVAC costs, making these power supplies both cost-effective and environmentally friendly.

EA bidirectional dc power supplies cone standard with arbitrary waveform function generator, swappable digital interface control and built-in test routines for battery test, photovoltaic simulation and MPP tracking.
