Description


Reduce network disturbances - saving energy costs.

The CNW 953 series has been developed especially for smoothing flows in regenerative converters. The series is designed for normal operation as mains choke and also for the regenerative feedback operation for smoothing of the current.The CNW 953 is also suitable for use as a filter choke in LCL filters.

By using a mains choke the inverter electronics and DC bus capacitors are protected.

Starting currents and current peak are attenuated up to 60%. 

Mains chokes help to comply with international power quality standards IEEE 519 or EN 61000-3-2.
