12V 24V 36V 40A PWM DC Motor Speed Controller | Forward-Reverse Switch with Case

Description

The 12V 24V 36V 40A PWM DC Motor Speed Controller is a robust, high-current speed regulation device engineered to govern the performance of high-power DC brush motors efficiently. Featuring heavy-duty automotive relays and advanced pulse-width modulation (PWM) circuitry, this controller provides precise linear speed adjustment, torque regulation, and directional control.

Enclosed in a durable protective case, the unit integrates a 3-digit seven-segment LED display that shows the active operating voltage in real-time. It includes a user-friendly toggle rocker switch for instant forward and reverse direction switching, along with a 100K potentiometer knob for smooth 0-100% speed scaling. Designed with secure fence terminal blocks, it ensures safe and stable high-current wiring connections for demanding industrial and robotic applications.
