ZK-PP1K Dual Mode LCD PWM Signal 1-Channel 1Hz-150KHz PWM Pulse Frequency Duty Cycle Adjustable Square Wave

P roduct D escrtion

1.PWM signal , square wave rectangular wave signal ;

2.Used to generate a square wave rectangular wave signal, which is supplied to a DC motor or a ster motor driver; Ster motor, servo motor, electric grper, arm;

3.Combine the driver to realize dimming, speed regulation, control solenoid vae, etc. However, it is not poible to directly drive loads such as electric lights, motors, and solenoid vaes.

Highlights:

1. 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 mode - positive pulse width time, negative pulse width time, delayed start time, and adjustable number of pulses.

2. With start-stop on, external switch can also be used to control output signal ON/OFF.

3. Wide voltage input 3.3-30V, with anti-re protection, 5.08mm terminal wiring.

Technical P arameters:

1. Working voltage: 3.3~30V, with anti-re protection ;

2. Frequency range: 1Hz~150KHz, accuracy about 1% ;

3. Duty cycle range: 0-100%, 1% sting ;

4. Number of pulses: 1-9999, or infinite (display '----' stands for infinity) ;

5. Delay output time: 0.000s-9999s, the minimum can be set 1ms ;

6. Positive and negative pulse width length: 0.000s-9999s, the minimum can be set 1ms ;

7. Signal loading capacity: le than 30mA ;

8. Output signal amplitude: amplitude is equal to the supply voltage ;

9. Product size: 79mm*43mm*30mm ;

10. Product Weight: 40g ;

11. Packing: Anti-static bag.

1.on operation instructions

· There is an output waveform when power is turned on;

· Waveform amplitude = power supply voltage;

· The number of output pulses reaches the set value, the output is automatically stopped, and'oUT ' disappears;

· Pre the ON on to control the presence or absence of the waveform. OUT disappears to indi-cate no output waveform, and output o;

· Power-on reset or ON on to turn on the output, recalculate the number of pulses;

2.PWM mode (display has "%" for PWM mode)

The factory default mode is PWM mode, FREQ+ and FREQ-key set frequency, DUTY+ and DUTY-on set duty cycle; short pre ON on 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%.

If you want to switch to PULSE mode, long pre the SET on (more than 6 seconds), do not release, you will see the screen change, "%" disappears, it is PULSE mode.

3.PULSE mode (No "%" on the right side of the display is PULSE mode)

The line above the LCD screen displays the positive pulse width time. The P+ and P- ons set the parameter. The line below the LCD screen displays the negative pulse width time. The N+ and N- ons set the parameter. Pre the ON on 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.

Pulse number and delay time setting - In PULSE mode, pre and hold the SET on 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- ons set the delay time, N+ and N- ons set the number of pulses, the factory default delay time is 0 seconds, the number of pulses is infinite (display ----); then pre SET on 2 In seconds, it will automatically return to the pulse interface, pre the ON on, after the delay setting time, start to iue the set number of pulses. If the number of pulses is sent, it will automatically output 0. If the period is not sent, preing the ON on will turn off. The output pulse is turned off and cleared, and the set number of pulses is iued each time it is started. After the number of pulses is sent, the display 'OUT' automatically disappears.

4 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 pre the start on, 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 pre the start on, 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, thenegative pulse width is set to 0, the delay time is set to 10.00 seconds, and the pulse number is infinite. (----).
