The 6 Best 30 A Speed controllers (2023 reviews)

For a low asking price, wowoone 30 a speed controller has managed to overwhelm their customers by packing as many features as they could. It can work to control a fan motor, but you need to know the power requirements for your motor as this speed controller is only rated for up to 12volts. It's a little mobile that spins around in a circle with a slightly heavier rowboat for balance. It fits snuggly in the battery case but is a 4v battery. It can be used as motor control for an enterprise model kit. It comes with a self-recovery fuse 2a and a power-on led light. It provides good linear control of the fan.

Why We Like This:

Ultra-low voltage dc motor governor with switch function
Easy hook up and easy to use
Has a power cap on board
Positive supply in order to protect the circuit from any possible short circuits

Bojack 30 A Speed Controller

Buy on Amazon

The bojack 30 a speed controller should be able to handle its purpose and duties with ease. The DC computer fan uses an electronic commutation method for maintaining rotation (brushless), install 1000uF to 4700uF 25V capacitor to smooth out Pulse Width Modulation (PWM) output from control module going into PC fan motor. It has its own 2a self-recovery fuse, which will automatically disconnect when the current is too high, and will automatically recover after the fuse cools down. Without this strip, the threads will protrude enough to mount through a hole and secured with the nut. It includes an off position, which is a nice addition.

The knob is nice with a very visible red line. They run the motor at a max speed of maybe 20% of full. It is adjusting the dc voltage in an accurate way. There is a score line that allows you to snip off the "extra" circuit board. It is a very nice pulse width modulation (pWM) board for the money.

Why We Like This:

Worked great on a small motor
Pwm dc motor speed controller, with switch function, with start-up led light
Controls speed but does not zero out

Enmja 30 A Speed Controller

Buy on Amazon

The enmja 30 a speed controller is suitable and reliable and fits well with your daily purpose. The PWM dc motor speed controller has the functions of running, stopping and braking. It provides output to produce both broadcast and spot application patterns. This is used to control two 550 motors on a powerwheels ATV on a 18V tool battery. The potentiometer range is 1 ohm to 94k ohms and uses a three wire JST connector. It can get the maximum output current of 30a, which can provide enough driving capacity for the motor.

The potentiometer center wire is neutral and the other 2 wires are opposite resistance values depending on the knob position. It works well with a 12 volt dc water pump. The motor speed control switch has a knob with switch function.
