Description


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.
