The DC3.3-30V High Power PWM Driver Motor Speed Controller is a versatile device suitable for driving motors, solenoid valves, LEDs, and other loads with a current under 8A. It features a MOS switch type output, where the waveform is generated only when the load is connected. This PWM driver supports two operational modes: PWM mode and pulse mode. In PWM mode, both frequency and duty cycle are adjustable. In pulse mode, parameters such as positive pulse width, negative pulse width, power-on delay start time, and number of pulses can be adjusted. The driver allows for LED brightness control, motor speed regulation, and can operate solenoid valves for automated pull and release cycles. It has a wide input voltage range of 3.3-30V and includes start and stop buttons with 5.08mm terminal wiring. The digital display features a wide viewing angle for easy monitoring of settings. With compact dimensions of 79 x 43 x 30mm and a weight of 42g, the unit is lightweight and easy to install. It is constructed from durable plastic material and operates within a voltage range of 3.3-30V. Frequency adjustment ranges from 1Hz to 150kHz with approximately 2% accuracy. Duty cycle is adjustable from 0% to 100% in 1% increments. Pulse count can be set from 1 to 9999 or configured for continuous operation. Delay output time is adjustable from 0.000s to 9999s, with a minimum setting of 1ms. Positive and negative pulse widths can each be set from 0.000s to 9999s, also with a minimum of 1ms. The output load capacity is under 8A, and the output amplitude matches the supply voltage. Package includes one PWM driver. Key Features: MOS switch type output, dual-mode operation (PWM and pulse), LED brightness adjustment, motor speed control, wide 3.3-30V input range, compact and lightweight design, wide frequency and duty cycle range, output load capacity under 8A.
