Press Release Summary:
With 5-limb body, Series CNW 910 and CNW MC 835 are indispensable to electromagnetic compatibility of entire system. Units can be used as 3-phase network chokes or motor chokes, and in standard version are dimensional for nominal currents up to 1,200 A. Additional unwound limb ensures chokes are able to both transmit and damp common-mode noise until such time as it can be ultimately conducted to earth.

REO-USA Introduces a New Generation of 5-Limb Chokes
INDIANAPOLIS – REO-USA has introduced its new generation of CNW 910 and CNW MC 835 series of 5-limb chokes, offered with or without water-cooling the devices can be either used as three-phase network chokes or motor chokes, and in the standard version are dimensional for nominal currents up to 1,200 amperes.
In addition to huge savings in weight and volume – up to 40% and combined with low thermal heating - due to their special 5-limb body they are indispensable to the electromagnetic compatibility (EMC) of the entire system.
“When using regenerative converters, chokes are generally employed to provide clean, sine wave-shaped power. Depending on the type of converter, common-mode interference can occur, creating additional thermal loading on the choke,” remarked Rick Jones, Senior Director of Engineering for REO-USA.
“Similar problems occur with motor chokes generally known to allow longer motor supply lines and designed to protect the motor and its insulation. In both cases, magnetic fields lying outside the core can seriously affect components located in the vicinity of the choke.”
Jones said an additional unwound limb ensures the choke are able to both transmit and damp common-mode noise until such time as it can be ultimately conducted to earth. The new generation of REO-USA chokes not only provides an effective solution to these problems, but also demonstrates low levels of noise emission. Space-saving design and reduced manufacturing costs make the new chokes even more cost-effective.
