This PWM motor uses two high-voltage and low internal resistance MOS tubes, as well as the front-stage driver, with more stable performance. With digital tube display to display motor regulation duty cycle, upper and lower duty cycle limits, and frequency. Adopts a rotary knob for motor speed adjustment, turn left to decrease speed, and turn right to increase speed; short press it to control motor starts/stops, and long press it to enter into setting mode. Features: High Power and More Stable: Uses two high-voltage and low internal resistance MOS tubes, as well as the front-stage driver, with more stable performance. Supports high voltage and high power. Digital Tube Display: Support to display motor regulation duty cycle, upper and lower duty cycle limits, and frequency. High Precise: The digital encoder adopts a rotary knob for motor speed adjustment, which is more precise than ordinary potentiometer adjustment, better consistency, and no drift. Rotary Encoder: Turn left to decrease speed, and turn right to increase speed; short press it to control motor starts/stops, and long press it to enter into setting mode. Indicator Light: Equipped with a motor status indicator light that illuminates on startup and extinguishes on shutdown. Motor Soft-starts Function: The current increases slowly when the motor starts, with no inrush current, does not damage the battery, effectively protects the motor, and prolongs its service lifespan. Automatic Starts-stop: It is equipped with a start/stop button. It can be controlled by an external switch to meet the customer's multiple control needs, more convenient. Practical Scenarios: Used to generate square and rectangularwave signals to control direct current motors or stepper motor drivers; used for servo motors, stepper motors, electric grippers, replacing PLC pulses, and more. PULSE mode can control the number of pulses, which can control the number of turns of the stepper motor! Wide Applications: Matching driver to realize dimming, speed control, control solenoid valves, etc., but can not directly drive the lamp motor solenoid valves and other loads.
