Specification Brand : YWBL-WH BulletPoint1 : [Soft-start Function] The controller ensures a gradual increase in current during motor start-up, eliminating inrush current to protect the battery, prolong motor lifespan, and prevent damage. BulletPoint2 : [Display and Control] Easily monitor and adjust motor regulation duty cycle, upper and lower duty cycle limits, and frequency with the digital tube display. the knob enables quick speed adjustments for optimal motor performance. BulletPoint3 : [Versatile Usage] Ideal for controlling direct current motors, stepper motor drivers, servo motors, stepper motors, and electric grippers. the pwm generator can be used for dimming, speed control, and controlling solenoid valves. BulletPoint4 : [High Voltage and Stability] This motor speed controller features two high-voltage and low internal mos tubes, along with a front-stage driver, providing more stable performance and supporting high voltage and power. BulletPoint5 : [Precise Motor Adjustment] The digital encoder allows for precise motor speed adjustment through a knob, offering better consistency than ordinary potentiometer adjustments.
