Used this to replace the variable pump controller on a waste oil burner that had gone bad, it would go very slow, and one one occasion had gone full speed. The OEM controller would have been many hundreds of dollars. I can't speak to the longevity of a Chinese controller..... but it does function as intended in an alternate application on a 90v DC motor, running at about 35v. Once I find an enclosure that fits, I will be adding an enclosure and cover to prevent the setting from getting bumped. Sorry about the 4 stars... I have a hard time giving anything Chinese "5 stars" unless it is a unique product or something that fulfills a unique need. This is just a reproduction of an OEM part.

This DC controller is advertised at 0 to 90 volts DC output. Unfortunately, at the highest setting, mine only puts out 70 volts. I might have a defective controller but by the time I pay to send it back, I might as well just keep it for 70 VDC (maximum) use. It's sturdy though!

Used it to fix my dads tread climber. The circuit board went bad. So I wired this to the motor and 110v power and it works like a charm. Good deal, easy fix if you know a little about electrical. Also mounted it to the control pannel for easy adjustments.

It works but just barely. I am using it with my HF 7x10 mini lathe and though it does power it. It could be better.
