Review on PLUSPOE Dimmable Magnetic Transformer Compatible by Sean Julian

Bought this to pair with a Lutron PD-6wcl-wh dimmer switch for our church under table lights. This power supply did not disappoint. When connected to a Lou Tron dimmer, it provides an excellent dimming range for my 12V strip lights with no flicker and stable dimming ability. Under dimming load, it produces a very deep high-frequency hum or high-pitched tone. If you have it in the attic, basement, underground, or in a closet you probably won't have a problem, but you certainly don't want it to be where you can hear it, such as in a bedroom. B. under a cupboard. I've run it multiple times. Minutes under load with a buzz, and the block didn't seem to overheat. Overall this is a great device for the price, the only reason I'm giving it four stars is the hum under load.
