PWM Controller Module LED Signal Pulse Generator 1. LED brightness adjustment, frequency and duty cycle can be adjusted 2. Motor speed adjustment, frequency and duty cycle are adjustable 3. Drive the solenoid valve to engage and release, automatically cycle, delay output, cycle number (or infinite cycle) can be set 4. Control the on and off of equipment, conduct switch fatigue tests, voltage sag and other tests to verify the reliability of customer equipment 5. Delay start load, the delay time can be set, it will always be on or work intermittently after the delay 6. Can directly drive LEDs, motors, solenoid valves and other loads 7. Two modes can be selected: PWM mode - frequency (continuous), duty cycle, and number of pulses are adjustable; PULSE pulse mode - positive pulse width time, negative pulse width time, power-on delay start time, pulse The number is adjustable 8. Equipped with start and stop buttons to control signal output and stop 9. Wide voltage input: 3.3-30V, 5.08mm terminal wiring 10. Working voltage: 3.3~30V (be careful not to reverse the positive and negative poles, otherwise they may burn) 11. Frequency range: 1Hz~150KHz. Generally, 20KHz is selected for motor speed regulation. 12. Number of pulses: 1-9999, or infinite (display ‘----’ means infinite) 13. Delay output time: 0.000s-9999s, can be set to 1ms (MIN) 14. Positive and negative pulse width length: 0.000s-9999s, 1msMIN can be set) 15. Output load capacity: less than 8A (MOS switch tube) 16. Output amplitude: The amplitude is equal to the supply voltage (OUT+ and V+ modules are directly connected internally) 17. Dimensions: 60x32mm 18. Weight: 20 grams
