Five-limb choke range targets EMI problems

REO UK has launched a range of five-limb chokes targeting electromagnetic interference (EMI) problems in industrial applications. The CNW range is available in two variants, the liquid cooled series-835 motor choke and the series-915 three-phase line choke.

Said to offer a 40% weight and volume reduction on previous models, the CNW range features high thermal dissipation and a maximum current rating of 1200A.

The recent rise of non-linear loads such as variable speed drives, used to improve efficiency and energy savings, has caused an increase in EMI and as facilities have grown, so has the tendency for longer cable runs. These issues have led to problems such as overheating windings, harmonic currents and voltage distortion, resulting in shorter product lifetimes and fines.

The CNW series is designed to dampen current peaks and voltage drops on the network caused by high frequency switching, smoothing the waveform and providing a clean sinusoidal current output.

The range of five-limb chokes is part of REO's drive to make a complete and high-performance range of electromagnetically compatible products available for applications ranging from industrial automation, food and beverage processing and packaging.
