Switch on DC microgrids in segments, operate and monitor them safely

DC microgrids are becoming increasingly important in industry. They enable an efficient and stable power supply and the simple integration of renewable energies and storage systems - essential for more sustainability and climate neutrality. Pre charge units enable controlled, sequential ramp-up of industrial DC microgrids. This means that loads such as drives, motors, or complex load circuits can be started one after the other to avoid current peaks. Our pre charge units are available in several performance variants. Operating mode and switch-on delay can be set directly on the device. Further setting and diagnostic options can be selected via the optional communication interface.
