About This Product

If you need to fine-tune the speed of a DC fan, blower, or heater, this motor speed controller is a simple and effective solution.

It's designed to work with both 12V and 24V DC appliances, so it covers a lot of common devices.

The built-in heat sink is a big plus – it keeps the unit cool even during extended use, which means better performance and longer life for both the controller and your motor.

The wiring is super straightforward with three color-coded wires, making it hard to mess up the connections.
Just match the colors and you're good to go.

The compact size – just 89 x 32 x 35mm – means it fits into tight spaces easily without cluttering up your project box or panel.

The knob gives you smooth, precise speed control from zero to full, so you can dial in exactly the airflow or heat output you want.
Great for DIY projects, bench testing, custom cooling setups, or even repairing old appliances.
Solid build quality, no flimsy parts.

If you're into building or tinkering with electronics, this little rheostat is a handy tool to keep around.
