70AEQ PWM DC motor speed controller with reversal, 12-60V/70A

Product detailed description

The 70AEQ DC motor PWM speed controller allows for smooth speed control of a brushed DC motor within a power supply range of 12–60 V and current up to 70 A, including direction of rotation changes via a forward/reverse switch. Regulation is performed using pulse width modulation (PWM) without changing the voltage, ensuring the motor maintains constant torque across the entire speed range – only the duty cycle changes. The speed is adjusted using the included rotary potentiometer (270°), while the included rocker switch handles power on and off. The robust aluminium housing with a heatsink and 80 A overcurrent protection make this controller ideal for electric scooters, bikes, trolleys, and other high-current DIY projects.
