MAKERELE 7-70V 30A PWM DC Motor Speed Controller, 1PC, Adjustable 12V-48V

Key features

• Wide Voltage and High Power:Wide voltage input DC 7-70V (70V is the maximum operating voltage, please leave some margin when using). The maximum motor drive current is 30A. At 12V, the maximum power is 300W; at 24V, it is 400W; at 48V, it is 450W; and at 60V, it is 500W.
• Multiple Protections:The DC motor speed controller is equipped with a 30A automotive-grade fuse to effectively prevent short circuits at the motor interface. It adopts high-quality high-voltage MOS tubes, three 100V high-frequency low-resistance capacitors, and a precision aluminum housing, providing excellent heat dissipation, precise parameters, and ensuring long-term stable operation, offering dual protection for your motor and controller.
• Detachable Soft Wire:The PCB board integrates a RUN/STOP/BRAKE three-function toggle switch. Please turn on the RUN switch when in use for intuitive and convenient operation. The soft wire for adjusting the potentiometer is detachable (15cm/5.9 inches in length), providing flexible and convenient installation.
• Stable Operation:It features an optimized PWM circuit design with a wide duty cycle adjustment range, offering a speed regulation range of 0-100%. The motor operates smoothly without noise or vibration. It has a power indicator light for clear visibility of the working status. The precise welding process makes it suitable for applications requiring long-term operation.
• Safety Wiring Tips:The 7 - 70V PWM motor speed controller is specifically designed for DC brushed motors. It needs to be powered by a separate DC power supply and should not be connected to an AC power supply or used to drive brushless motors. When wiring, please note: P+/P- connect to the positive/negative terminals of the DC power supply, and M+/M- connect to the motor (no need to distinguish positive and negative terminals; if the direction is incorrect, simply swap the two motor wires).
