Product Description:

Offered by Kollmorgen, the 3NF-30> mains filter is intended to be used along with the manufacturer’s AKD product group of servo drives. This filter is designed as a <. The product can be easily installed in confined spaces because of its compact size. This device is used to cut down on harmonic distortion and electromagnetic interference triggered during operation. The unit can perform the filtering process only if the allowed throughout rating is within the specified range even when the servo amplifier has a peak loading. Its power terminals tend to have a hazardous voltage of up to 10 minutes even after there is a disconnection of the mains voltage.

This filter is connected outside the servo amplifier. The product tends to have live power terminals immediately and soon after the operation period. This device must incorporate a fixed installation because of the high earth leakage currents produced by the system. The unit should be connected in accordance with the connection diagram given in the instructions manual of the servo amplifier. It should be ensured that the phase-to-phase voltages of the filter are de-energized before any work is done on it.

This filter can be used in several applications because of the wide operating range supported. The product must have a throughput rating that is higher than the maximum power consumption of the related servomotor or servo amplifier. This device comes with a current rating of 30 A. The unit also portrays a rated voltage of 480 VAC. Its IP 20 protection rating indicates that it needs a control cabinet for its mounting. This mains filter helps to minimize energy loss with its high efficiency.
