Description


Voltage rise (<200V / us) and distortion reduce - protect electrical consumers optimally.

Motor chokes in fully encapsulated version are specially designed for rough environments and offer a very good mechanical protection of the component. The fully encapsulation allows design up to protection ratings IP 66.

Losses and heating are minimized and the leakage current reduced. Longer motor cable lengths are possible. By limiting the rate of voltage rise, the motor insulation is protected and thus prolongs the life. The motor choke also attenuates the conducted interference in lower frequency range very good. The losses and the typical noise in the motor plate can be reduced. Voltage rise (<200V / us) will be reduced.

Increasing the service life of motors, reduction of edge steepness dv/dt to earth and between phases, reduce motor noise, current smoothing.

  • Rated voltage: U ≤ 3 x 500 V
  • Reduce the voltage rise dv / dt to <200V / us
  • Field frequency: 0 - 60 Hz
  • Drive switching frequency: up to 150 A >4kHz, from 150 A >1,5KHz
  • According to: EN 60289 / EN 61558
  • Test voltage: L-L 2500 V, AC/50Hz 60s; L-PE 2500 V, AC/50Hz 60s
  • Insulation class: T40/F
  • Protection rating: IP00-IP65
  • Climatic categorie: DIN IEC 60068-1
  • Overload: 1,5 x INenn 1 min / h
  • Ambient temperature: 40 °C
  • Design: standing on foot angle
