High Power PWM & Pulse Generator ZK-PP2K Frequency Duty Cycle Adjustable Driver FP S202412304785 Specification: Working Voltage: 3.3~30V (note that the positive and negative poles should not be reversed, otherwise it may burn) Frequency range1Hz~150KHz, accuracy about 2%. Motor speed control generally choose 20KHz Duty Range: 0-100%, 1% step Number of pulses1-9999, or infinity (display "----" represents infinity) Delayed exit time0.000s-9999s, limit can be set to 1ms Positive and negative pulse width]: 0.000s-9999s, limit small adjustable to 1ms Output capacity: less than 8A (MOS switching tube) Output amplitudeamplitude and supply voltage same (OUT+ and V+ module internally directly connected) Product Size79*43*30mm Product Weight42g Characteristic: 1. Direct drive for ED, motor, solenoid valve and other loads 2. Two modes can be selected. PWM mode one - frequency (continuous), duty cycle. Note that the number of switches cannot be adjusted in this mode, it turns on and off constantly; PULSE pulse mode - positive pulse width time, negative pulse width time, on-delay start time, adjustable number of switches 3. With start-stop button to control start and stop 4. Wide voltage input 3.3-30V, 5.08mm terminal wiring The package includes: 1*High Performance ZK-PP2K PWM & Pulse Generator Frequency Duty Cycle Adjustable Driver
