What is the issue if a PDL 620K dimmer is humming, being used with electronic transformer at 700watts
As the 620K is a leading edge dimmer it is not suitable for electronic transformers.
The transformer should be changed for a wire wound or the dimmer should be replaced with trailing edge, though as we only do 450w rated dimmers the load would have to be split between two dimmers.
The PDL620K is no longer available.
