Add to compare

The PowerKraft Power Supply Solution is a power supply system designed for hydrogen production applications, particularly electrolytic processes. It is based on time-proven thyristor technology and consists of a separate transformer and rectifier panel. The system provides a DC output voltage range of 150–1000 V and current range of 1500 A to 10 kA. It supports 3-phase AC input voltages from 380 V up to 33 kV and is designed for continuous operation at rated load up to 1000 m altitude. The system includes protection features such as overcurrent, overvoltage, thyristor overtemperature, fuse failure, and transformer overtemperature. It is compatible with modern Fieldbus systems and supports Profinet and 4–20 mA analog control interfaces. Cooling options include forced air and water cooling.
