The control knob that increases/decreases power to the circuit completely failed. Now, I have a $60 brick that acts like an on/off switch. This is a huge disappointment as I bought this solely for the dimming capabilities. It's not like this was used all the time either. I have probably turned the knob maximum 30-40 times. I only ran about 5amps through it at 24v at a time, so this was a terrible waste of money.

Was well made and worked so far.

I installed this in an electric go kart. I’m running a 24v battery to a 30 amp circuit breaker, the speed controller (rated at 40 amps, and 36 volts). I only drove this at 3miles per hour. It didn’t go far before it started smoking and smelled burnt! I don’t think I had the speed up to 3 on the dial. Totally useless!

Used a volt meter to verify that it only output voltage to the motor when the switch was set to reverse. On forward it output no voltage.

Motor connected directly to battery, red to red and black to black, motor goes forward. Motor connected through controller, red to + and black to -, forward switch is reverse. So I reversed the polarity to the battery and it blew several capacitors and started smoking. Not accurate.

The design is perfect for what I needed, but I was quickly disappointed when the voltage controller stopped working and no longer controls the voltage. It only allows the full voltage of the power supply to be used with no ability to set a desired voltage.

El diseño es perfecto pero el producto no funciona
