CleanSweep® DIN Rail Narrow Band PLC Filter

New Button.png

PLC, or power line communication, is a powerful tool to control equipment without adding wires or alternative communication channels.  PLC is not without its challenges, however.  PLC signals often reach equipment for which they were not intended to.   Creating multiple PLC networks on the same AC power line is asking for troubles.  Strong EMI interferes with PLC signals usually located in the same band as typical EMI.  

CleanSweep® AM series DIN rail PLC filters answer all the above challenges.  They serve as a separation junction for two separate narrow-band PLC networks on the same AC main.  Fully symmetrical design of the filter effectively blocks propagation of PLC signals from one network without affecting another - on the same AC mains.  And if you have just one PLC network AM series filters will protect is from extraneous EMI from power lines.

AM series filters work with most standards for narrow-band PLC, including most of CENELEC bands, FCC, ARIB, and IEEE1901.2.
