DZS Elec 10A 12V-40V DC Motor Speed Controller 12V 24V PWM Variable Speed Regulator Governor Switch CCMHCN With Speed Control Knob

As expected

Didn't handle the high amp

Used this to replace a bad wire feed motor driver board on a Harbor Freight Mig170 welder. I secured the old board out of the way with wire ties as it has other circuitry on it that still works. I installed this board using the potentiometer nut in the original hole. I installed a 24vdc power supply (240vac rated) to the pains terminals and wired the output in series with the trigger wire. It fed wire perfectly and brought the welder back to operation. I did add some hot glue to support the board and prevent it from touching anything. It is nice that it has a heat sink to keep it cool as the original one did not. Great little board and appears to be well built.

These work really well, my only complaint is that the knob needs to be run through a panel as the only thing keeping it attached is solder. otherwise electrically pretty durable, i’ve accidentally shorted one a bunch of times and it still works with no issues. great price

Works fine. Heat sync is a little fragile. Used it on a wiper motor for a Halloween prop.

This is a great dc-dc controller, 12-24volt 10amp max. It worked great for my Halloween props controlling windshield wiper motors.. 👍

I like to play with projects, and I created a leaf blower out of an old vacuum motor. This controller helps me soften the enormous speed of the vacuum motor. Works great, wide range, recommended.
