ZK-PP1K PWM Pulse Frequency Duty Cycle Signal Generator High-precision Detection 1Hz~150KHz Square Wave Signal Stable
ZK-PP1K PWM pulse frequency duty cycle adjustable module square wave rectangular wave signal function generator
Description:
1.PWM signal generator, square wave rectangular wave signal generator
2. Used to generate a square wave rectangular wave signal, which is supplied to a DC motor or a stepper motor driver; Stepper motor, servo motor, electric gripper, robot arm
3. Combine the driver to realize dimming, speed regulation, control solenoid valve, etc. However, it is not possible to directly drive loads such as electric lights, motors, and solenoid valves
Features:
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 button, external switch can also be used to control output signal ON/OFF.
3. Wide voltage input 3.3-30V, with anti-reverse protection, 5.08mm terminal wiring
Technical parameters:
Working voltage: 3.3~30V, with anti-reverse protection
Frequency range: 1Hz~150KHz, accuracy about 1%
Duty cycle range: 0-100%, 1% stepping
Number of pulses: 1-9999, or infinite (display '----' stands for infinity)
Delay output time: 0.000s-9999s, the minimum can be set 1ms
Positive and negative pulse width length: 0.000s-9999s, the minimum can be set 1ms
Signal loading capacity: less than 30mA
Output signal amplitude: amplitude is equal to the supply voltage
Product size: 79mm*43mm*30mm
Product Weight: 40g
Packing: Anti-static bag
Module description:
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 ON 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%.
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.
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- 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 ON 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.
Pulse number and delay time setting - In PULSE mode, press and hold the SET button for 2 seconds and then release, enter the pulse numb
