Powerful DC motor speed controller with bidirectional capability Key benefits Broad compatibility and strong performance: designed for DC power supplies from 10V to 55V and capable of handling up to 60A peak and 40A continuous current, with a smooth 0100% speed range. Convenient control: potentiometer with a builtin switch function provides easy throttle control and on/off operation in one unit. Durable and efficient design: outer casing protects the controller board from damage and helps dissipate heat for reliable longterm operation. Flexible motor direction: bidirectional rotation setting enables reversing the motor's direction as needed. Specifications Input supply voltage: DC 10V55V Maximum current: 60A Continuous current: 40A Speed range: 0100% Key features Potentiometer with switch function for simple, combined speed and power control power speed controller switch enhances adaptability across applications Robust outer casing protects internal electronics and aids heat dissipation Bidirectional optional direction setting to reverse motor direction when required Use scenarios DIY robotics and automation: drive mobile robots or robotic arms with smooth speed control and easy direction changes. Small conveyor or belt systems: manage motor speed precisely for gentle starts/stops and reversible operation. Hobbyist workshops and CNCstyle setups: integrate into projects needing adjustable motor speed with the option to reverse rotation without extra wiring. This controller is suitable for applications requiring a wide input voltage range, current capability, and reliable protection for the controller board while delivering flexible, bidirectional motor control.
