Buzzed at 3W load, OK at 6W
on 4 February 2013
When driving one 3W LED, output was stable but unit had a high pitch buzz/squeal. Increasing the load to 2x3W caused the buzzing to stop, LED output is stable and flicker free. Since the internal wiring terminals are really only big enough for one cable, driving two LEDs had to be done with an external terminal block.
So best for a single load more than 3W.
