du/dt Choke N CNW 806

Three-phase dv/dt filter

Description

NEW SERIES! The new series not only scores points for its faster delivery time, but also for its resource conservation and increased efficiency. Reduce voltage rise to < 500V / µs – protect electrical loads and insulation cost-effectively. A simple and cost-effective method to reduce the voltage rise rate is to use a dv/dt choke or filter. It dampens the voltage rise to tolerable levels and prevents overvoltages on long supply lines. Losses and heating are minimized, and the leakage current is reduced. By limiting the voltage steepness, the motor insulation is protected, thus extending its service life. EMC interference in the radiation range from 1 MHz to 30 MHz is also reduced.

Benefits

  • Protection for electrical consumers
  • Limitation of voltage rise to < 500V / µs
  • extended service life for electrical consumers
  • low leakage currents on the motor
  • Reduced losses
  • Easy construction
  • compact design
  • Production according to UL insulation system E251513 possible

Typical application

Drive systems for motor drives, Mechanical engineering, Elevators / escalators, Pipes, Conveyor technology, Ventilation and air conditioning, Robotics, Automation technology, Power supplies, Wind turbines
