Energy Distribution and System Safety

The product family within this category includes components that simply make the high voltage system in a mobile work machine safe. They interconnect and monitor the system.

A so-called Brake Chopper, the powerMELA-BC, monitors the high voltage network and protects it from overvoltage. It is often used as an electric brake/retarder, i.e. electronic braking in mobile machines. The braking power of the powerMELA brake chopper can be tailored to the requirements of a specific customer application and united with other STW Components (inverter, insulation monitor, power distribution unit etc) in a single housing as a modular power system unit (HV PDU). The switching module (HV KM) ensures safe input and output in high voltage systems with high power.
