Power Supply Unit

Power Supply Units (PSUs), also known as industrial power sources, form the central link between the public power grid and the electrolyzer. Their primary task is to convert the incoming alternating current (AC) into direct current (DC). The control system ensures that voltage and current are optimally adapted to the specific requirements of the respective electrolysis system.

Reliable Supply – Even Under Fluctuations
BeXema power supplies deliver stable, controllable DC voltage even under fluctuating conditions and adapt precisely to the requirements of the electrolysis system. They ensure efficient and reliable operation while enhancing performance, safety, and system longevity.

They are characterized by high efficiency, low losses, and excellent grid compatibility, ensuring a stable and precisely tailored DC power supply for electrolysis systems. This enables reliable and cost-effective operation of electrolyzers, particularly in industrial applications.
