HIGHLIGHTS Can directly drive LED, motor, solenoid valve and other loads Two modes can be selected: PWM mode - frequency (continuous), duty cycle. Note that the number of pulses cannot be set in this mode, and the pulse is always emitted. PULSE pulse mode - positive pulse width time, negative pulse width time, power-on delay start time, and number of pulses are adjustable. With start and stop button, can control the output and stop of the signal Wide voltage input 3.3-30V, 5.08mm terminal wiring TECHNICAL PARAMETERS Working voltage: 3.3~30V (note that the positive and negative poles should not be reversed, otherwise it may burn out) Frequency range: 1Hz~150KHz, the accuracy is about 2%. Motor speed control generally chooses 20KHZ Duty cycle range: 0-100%,1% stepping Number of pulses: 1-9999, or infinite (display ---'- stands for infinity) Delay output time: 0.000s-9999s, the minimum can be set 1ms Positive and negative pulse width length: 0. 000s-9999s, the minimum can be set 1ms Output load capacity: less than 8A (MOS switch tube) Output amplitude: The amplitude is equal to the supply voltage (OUT+ is directly connected to the V+ module) Product size: 79mm*43mm* 30mm
