Mains chokes N CNW 905

Three-phase line reactor 2% Uk

Description

Compact & Efficient

The new series not only scores points for its faster delivery time, but also for its resource conservation and increased efficiency.

Power Noise Reduction – save up to 15% energy costs. A line reactor relieves the supply network by compensating the harmonics reactive power. The harmonics and commutation notches are reduced strongly. By using a line reactor the inverter electronics and DC-capacitors will be protected.

Starting currents and current peaks are reduced up to 30%. Line reactors help to comply with international power quality standards IEEE 519 or EN 61000-3-2.

Advantages

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