Dimming - How does PLC interference suppression work?

In order to suppress the disruption from PLC signals, Niko has added a PLC interference suppression into the range of universal dimmers. As a result of the ripple effects, the PLC signals cause a disruption of the synchronisation at the zero-point passage of the sinewave alternating current. The Niko PLC interference suppression means that the dimmer sends a constant, dimmed signal to the lamp, suppressing any flicker and humming. Niko PLC interference suppression also prevents lamps from blinking in the event of a sudden reduction in grid frequency (+/- 3Hz).

Note: The PLC interference suppression feature of Niko universal dimmers does not remove the ripples on the sinewave alternating current. They continue to pass through the dimmer towards the lamp and the electronic LED lamp driver. Niko has noticed that lower quality LED lamps are more susceptible to PLC signals. These light sources will continue to flicker, buzz or hum despite the PLC interference suppression of the Niko dimmer.
