Mains Choke N CNW 905

Three-phase mains choke 2% Uk

Power Noise Reduction – save up to 15% energy costs. A mains choker relieved the supply network by compensating the harmonics reactive power. The harmonics and commutation notches are reduced strongly. By using a mains choke the inverter electronics and DC-capacitors will be protected.
Starting currents and current peaks are reduced up to 30%. Mains chokes helps to comply with international power quality standards IEEE 519 or EN 61000-3-2.

Advantages

  • Compact design
  • Extended life-time of electrical consumers
