Customer Reviews for Variac Auto Transformer Variable 2KW LCD Regulator Universal Plug Power Supply

Fast shipping, quality product at great price point. !

I’m glad I bought this unit as the outlet voltage was 127 volts and that is hard on electronic tube or solid state equipment. I have a lot of money in amps and test equipment that I need to take care of. It’s a great way to protect your things!

The unit I received has these accuracy characteristics: [at low end +5V, accurate around 114V, and at high end -2V]. They're probably just feeding an ADC with a potentiometer or rheostat coupled to the main shaft, and not actually measuring any output voltage, this gets you a rough ball-park figure or a semi-accurate one depending on the position of the knob. Decent packaging. Comes with no literature. Be warned: other reviewers say the chassis is NOT grounded!

Meter is not accurate at all. Added a digital voltmeter, was an easy addition and made it much more accurate.
