Surge Suppression Unit


  • The cable between the inverter and the motor comes in two lengths: 50m and 100m.
  • The surge voltage can be suppressed to 1kV or lower by connecting the surge suppression unit on the motor.
  • Applicable motor capacity: 0.2kW to 75kW
  • Since no additional work is required, it can be easily mounted on the existing equipment.
