Motor speed adjustment, frequency and duty cycle can be adjusted. Drive the solenoid valve 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 start load, delay time can be set, after the delay, it will be turned on or intermittently.
3.2 PWM mode (display has "%" for PWM mode) The factory default mode is PWM mode, FREQ+ and FREQ-key set frequency, DUTY+ and DUTY-button set duty cycle; short press STOP button control signal output or stop, stop output is 0, the sn displays "OUT" mark as There is output, otherwise it stops output; the default factory frequency is 1KHZ and the duty cycle is 50%.
If you want to switch to PULSE mode, long press the SET button (more than 6 seconds), do not release, you will see the sn change, "%" disappears, it is PULSE mode.
Colour: Black. material: plastic
1. Highlights: 1.1 can directly drive LED, motor, solenoid valve and other loads
1.2 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.
1.3 With start and stop button, can control the output and stop of the signal
1.4 Wide voltage input 3.3-30V, 5.08mm terminal wiring
2. Technical parameters:
2.1 Working voltage: 3.3~30V (note that the positive and negative poles should not be reversed, otherwise it may burn out)
2.2 Frequency range: 1Hz~150KHz, the accuracy is about 2%. Motor speed control generally chooses 20KHZ
2.3 duty cycle range: 0-100%, 1% stepping
2.4 number of pulses: 1-9999, or infinite (display '----' stands for infinity)
2.5 delay output time: 0.000s-9999s, the minimum can be set 1ms
2.6 positive and negative pulse width length: 0.000s-9999s, the minimum can be set 1ms
2.7 output load capacity: less than 8A (MOS switch tube)
2.8 Output amplitude: The amplitude is equal to the supply voltage (OUT+ is directly connected to the V+ module)
2.9 Product size: 79mm*4m*30mm
2.10 Product Weight: 42g
