powerMELA SYSTEM SAFETY

  • Developed for use in mobile machines
  • Control via CAN bus
  • Customer-specific integration possible 

The high intermediate circuit voltage of max. 800 VDC for the electrification of mobile machines also requires components which guarantee the system safety. System-specific parameters such as the intermediate circuit voltage and the insulation resistance are permanently monitored through measurements. If deviations occur, remedial measures are initiated. The STW insulation monitor is used to monitor the insulation resistance. This features a new measuring procedure which supplies measuring results in a quicker, simpler way. In addition, it can determine the leakage capacitance in a system. 
Overvoltages in the intermediate circuit are prevented by the brake chopper. If a voltage threshold is exceeded, the brake chopper connects high load resistances which transform the excess energy into heat and dissipate this heat via oil cooling.
All the components for system safety are available either in a standalone variant or can be adapted to the specific customer application and integrated into STW system products.
