This high-power PWM driver is a MOS switch type output. When the load is not connected, there is no waveform, and the waveform appears only after the load is connected. load is connected. Suitable for direct drive motor, solenoid valves, LED and other loads, the current is less than 8A. Two modes design, frequency (continuous) and duty cycle adjustable under PWM mode, and Positive pulse width time, negative pulse width time, power-on delay starts time, and number of pulses are adjustable under pulse mode. Features: This high-power PWM driver is a MOS switch type output. When the load is not connected, there is no waveform, and the waveform appears only after the load is connected. Suitable for direct drive motor, solenoid valves, LED and other loads, the current is less than 8A. It can also be used in series with power resistors to achieve high current PWM output with reverse waveform and current less than 100mA. Support LED brightness adjustment, motor speed adjustment, frequency, duty cycle can be adjusted. Drive the solenoid valves to pull and release, automatic cycle, delay output, cycle number (or infinite loop) can be set. Control equipment to turn on and off, do switch fatigue test, voltage sag and other tests to verify the reliability of customer equipment. Delay starts load, delay time can be set, after the delay, it will be turned on or intermittently. 3.3-30V wide voltage input, with starts and stop button, and 5.08mm terminal wiring. Two modes can be selected, PWM mode and pulse mode, you can choose depending on your demands. PWM Mode: Frequency (continuous) and duty cycle adjustable. Note that the number of off and on times cannot be set in this mode, which keeps cycling on and off. Pulse Mode: Positive pulse width time, negative pulse width time, power-on delay starts time, and number of pulses are adjustable. All setting parameters are not lost on shutdown. Digital display with wide viewing angle design, the display has "%" for PWM mode, the right side of the display without "%" for PULSE mode. Specifications: Name: PWM Driver Material: plastics Operating voltage: 3.3-30V (note that the positive and negative poles should not be reversed, otherwise it may burn-up) Frequency ranges: 1Hz-150KHz, accuracy is about 2%. Motor speed control generally choose 20KHZ Duty cycle ranges: 0-100 %, 1% step Number of pulses: 1-9999, or infinities (display "----" represents infinities) Delay output time: 0.000s-9999s, minimum 1ms can be set Positive and negative pulse width length: 0.000s-9999s, the minimum can be set to 1ms Output load carrying capacity: less than 8A (MOS switching tube) Output amplitude: amplitude equal to the supplying voltage (OUT+ and V+ module internal direct connection) Item size: 79 * 43 * 30mm / 3.11 * 1.69 * 1.18in Item weight: 42g / 1.48ounce Package size: 80 * 30 * 45mm / 3.15 * 1.18 * 1.77in Package weight: 45g / 1.59ounce Packing List: 1 * PWM Driver
