WALFRONT DC 6-60V 12V 24V 36V 48V 30A PWM DC Motor Speed Controller (PWM) Speed Adjustable Stepless Governor Regulator Motor Speed Controller with Start Stop Switch

The unit worked exactly as described.

I needed to be able to adjust speed of the motor for a miniature vacuum pump that is a brushed type permanent magnet motor. It works smoothly down to half speed limited there due to the limitation of the motor, that motor is designed with only two commutator bars on the motor armature.

The media could not be loaded. I used this to replace the factory unit for my snow ex sander works great and saved me about $700 I had a dash made by a local metal shop and used magnets to mount it to the machine

I repair electronics in the medical field and have for 17 years.I installed this on my kids electric atv. I went down our driveway fine but on the way back up the unit popped this large capacitor inside the module. The atv has a protective circuit that limit the motor's draw to 30 amps. This unit's component cannot handle the advertised power and should not be purchased for any circuit that requires 30 amps.

Works great and easy to use was a great buy

It worked as I had hoped, however, there was absolutely no documentation included. I expected at least a wiring diagram. It did present me with a problem mounting the unit. You will need to mount the display in a panel, basically in a rectangular cutout. It would have been nice if they included a template for the cutout or that least the measurements.

The past was exactly as described and it works excellent

DO NOT PURCHASE IF YOU NEED 30 AMP CAPABILITY!The first time I plugged this in, I turned up the speed and it immediately blew the power control circuit. Full power all the time regardless of what the potentiometer position or power state (via the button).
