They are air-cooled and have many control, operating and display elements. Connections are made by means of easy-to-use screw terminals. The converters are distinguished by a high degree of efficiency of > 80% and comprehensive protective and control facilities such as protection from overload and overvoltage, thermal protection and decoupling diodes.
Options such as a varistor at the output, to prove additional overvoltage protection or a signal relay, further distinguish the GWH 100 / 500 series of converters. Up to 3 units with active current sharing can be switched in parallel to extend power.
