About This Product
This DZS Elec PWM controller is a workhorse for controlling DC brush motors in all kinds of projects.

It runs on 9 to 60 volts DC, handles up to 20 amps continuous, and can push 1200 watts max – so it's got plenty of guts for most medium-duty motors.
Speed is adjusted with a potentiometer knob, and you can switch between forward and reverse with the built-in button.

Just be careful not to flip direction at high speed – that's a no-go.

The control frequency is 25KHZ, which gives you smooth, efficient speed regulation with low heat and good torque.

It's got mounting lugs for easy install, and the wiring is color-coded: red/black for power, blue/yellow for motor.
Dimensions are about 92x52x36mm, with a 7mm hole for the pot.

Great for bench tools, conveyor belts, fans, or any DC brush motor setup where you need variable speed and directional control.

Solid performance for the price.
