The DC3.3-30V High Power PWM Driver Motor Speed Controller is a versatile device suitable for direct driving motors, solenoid valves, LEDs, and other loads with a current less than 8A. It features a MOS switch type output, which means that the waveform only appears after the load is connected. This PWM driver supports two modes: PWM mode and pulse mode. In PWM mode, the frequency and duty cycle are adjustable, while in pulse mode, parameters such as positive pulse width time, negative pulse width time, power-on delay starts time, and number of pulses can be adjusted. The PWM driver also allows for LED brightness adjustment, motor speed adjustment, and can be used to drive solenoid valves for pulling and releasing in an automatic cycle. It has a wide voltage input range of 3.3-30V and comes with a starts and stop button as well as 5.08mm terminal wiring. The digital display with wide viewing angle design makes it easy to monitor the settings. With its compact size of 79 * 43 * 30mm and lightweight of 42g, the PWM driver is easy to install and carry. It is made of durable plastics material and has an operating voltage range of 3.3-30V. The frequency ranges from 1Hz to 150KHz with an accuracy of about 2%. The duty cycle ranges from 0-100% with a 1% step. The number of pulses can be set from 1 to 9999 or set to infinite. The delay output time can be adjusted from 0.000s to 9999s, with a minimum setting of 1ms. The positive and negative pulse width length can be set from 0.000s to 9999s, with a minimum setting of 1ms. The PWM driver has an output load carrying capacity of less than 8A and an output amplitude equal to the supplying voltage. It comes with a package that includes 1 PWM Driver.
