Review on π Walfront SCR Electric Voltage Regulator Dimmer Temperature Controller Motor Speed Controlling Module Board with Cooling Fan (4000W, 110V AC) by Reggie Hobbs
Cheap junk, don't buy
As mentioned in previous reviews, the controller only really works on the last 10% of the setting. This controller worked for about 30 minutes controlling the water heating element. I realized that I was no longer in control of my element, so I turned off the power and opened the case to inspect it. As you can see the capacitor is swollen and cracked and the adjustment knob is now free to turn. It was the 120V/1650W element that broke it, way below the maximum output of this unit.
- Easy to use
- Poor instructions
