Mains Choke N Cnw 905

Three-phase mains choke 2% Uk

DESCRIPTION

Power Noise Reduction – save up to 15% on 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 by up to 30%. Mains chokes help to comply with international power quality standards IEEE 519 or EN 61000-3-2.

ADVANTAGES

  • Compact design
  • Extended lifetime of electrical consumers
  • Low-temperature rise
  • Attenuation of current spikes up to 30%
  • Reduction of input current up to 15%
  • Low noise
  • Production according to UL insulation system E251513 is possible
