100% brand new and high quality
Features:
Drive LED, motor, solenoid value and other loads directly.
Can be used to adjust frequency and duty cycle, fit for regulating the brightness of LED and the motor's speed.
Two modes can be chose: PWM: regulating frequency (continuous) and duty cycle.The number of pulses can not be set in this mode, and the pulse is cycle on or off. PULSE: 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.
Widely used in industrial DC motor speed regulation, industrial conveyor belt speed regulation, lighting and lighting mediation, computer power supply cooling, DC fans, etc..

Module description:
I Button operation instructions:
1. MOS tube switch type output, no waveform;
2. The number of open times reaches the set value, the output is automatically stopped, and 'out 'disappears;
3. Press the On button to control the start and end of the out put. OUT disappears to indicate no output, Output shutdown;
4. Power-on reset of ON button to turn on the output, recalculate the number of open times;
II PWM mode (display has "%" for PWM mode)
1. 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 screen displays "OUT" mark as There is output, otherwise it stops output; the default
factory frequency is 1KHZ and the duty cycle is 50%.
2. If you want to switch to PULSE mode, long press the SET button (more than 6 seconds), do not release, you will see the screen change, "%"
disappears, it is PULSE mode.
III PULSE mode (No "%" on the right side of the display is PULSE mode)
1. The line above the LCD screen displays the positive pulse width time. The P+ and P- buttons set the parameter. The line below the LCD screen
displays the negative pulse width time. The N+ and N- buttons set the parameter. Press the STOP button to control the signal output or stop.
When the output is stopped, the output is 0. The screen displays "OUT" for output, otherwise it stops output; the default factory positive pulse
width is 0.5 seconds and the negative pulse width is 0.5 seconds.
2. Pulse number and delay time setting - In PULSE mode, press and hold the SET button for 2 seconds and then release, enter the pulse number
and delay time setting interface, the screen displays SET, it will be turned off and cleared after entering. ;P+ and P- buttons set the delay time, N+
and N- buttons set the number of pulses, the factory default delay time is 0 seconds, the number of pulses is infinite (display ----); then press SET
button 2 In seconds, it will automatically return to the pulse interface, press the STOP button, after the delay setting time, start to issue the set
number of pulses. If the number of pulses is sent, it will automatically output 0. If the period is not sent, pressing the STOP button will turn off.
The output pulse is turned off and cleared, and the set number of pulses is issued each time it is started.
IV Application Operation Examples
1. PWM output 20KHZ, 60% duty cycle: Select PWM mode, the frequency is set to 20.00, and the duty ratio is set to 060%.
2. The output is turned on for 0.6 seconds and turned off for 0.2 seconds. Infinite loop: select PULSE mode, the positive pulse width is set to 0.600,
the negative pulse width is set to 0.200, the delay time is set to 0.000, and the number of pulses is set to --- -.
3. Power on or press the start button, delay 5 seconds, then the output is turned on for 0.6 seconds, off 0.2 seconds, infinite loop: select PULSE
mode, positive pulse width is set to 0.600, negative pulse width is set to 0.200, delay The time is set to 5.000 and the number of pulses is set to --
--.
4. Power on or press the start button, delay 5 seconds, then output high level 10ms low level 10ms pulse 100: select PULSE mode, positive pulse
width is set to 0.010, negative pulse width is set to 0.010, delay The time is set to 5.000 and the number of pulses is set to 0100.
5. Power-on delay for 10 seconds, then permanently output signal: select PULSE mode, the positive pulse width is set to a number greater than 0,
the negative pulse width is set to 0, the delay time is set to 10.00 seconds, and the pulse number is infinite. (----).
Caution:
The positive and negative poles should not be reversed, otherwise it may burn out.
