## Overview

The ZK-PP1K PWM Pulse Signal Generator is a versatile, compact module designed for professional-grade signal generation. It supports dual modes—PWM continuous wave and pulse mode—with adjustable frequency (1Hz-150KHz), duty cycle (0-100%), and pulse parameters. Featuring a bright LED display and wide voltage input (3.3V-30V) with anti-reverse protection, it’s ideal for controlling motors, solenoids, and other industrial applications requiring precise waveform control.

Review: generador de frecuencia - funciona de maravilla
Review: I wouldn't recommend it I move on don't work - I got mine I don't even turn on I can't get mine to work I just bought it too it's just a pain in the ass return stuff to people around anymore and it's like almost better off just taking is whatever with it but yeah if you decide you want to do this don't go with this one there's many other ones out there that I'm sure probably work because this one doesn't work pure trash not worth sending back for $13

## Features

- ♥Product introduction: This series of products are PWM and pulse signal generators. There are PWM mode and pulse mode. Only one mode can be used at a time, but the two modes can be switched at any time.
- ♥Features: 1. Two modes can be selected: PWM mode - frequency (continuous), duty cycle. The number of pulses is not adjustable, and the waveform is continuously sent; PULSE pulse mode - positive pulse width time, negative pulse width time, delay start time, and the number of pulses are adjustable. 2. With the start and stop button (ZK-PP1K can be connected to an external switch to control the output signal ON/OFF). 3. Wide voltage input 3.3V-30V, with anti-reverse connection protection.
- ♥Product Specifications: 1. Working voltage: 3.3V~30V, with anti-reverse polarity protection 2. Frequency range: 1Hz~150KHz, the accuracy is about 1% 3. Duty cycle range: 0-100%, 1% step 4. Number of pulses: 1-9999, or infinite (display '----' means infinite) 5. Delay output time: 0.000s-9999s, the minimum can be set to 1ms 6. Positive and negative pulse width length: 0.000s-9999s, the minimum can be set to 1ms 7. Signal carrying capacity: ZK-PP1K: less than 30mA
- ♥Operation explanation: 1. There is an output waveform when powered on; 2. Waveform amplitude = power supply voltage; 3. When the number of output pulses reaches the set value, the output will be automatically stopped, and 'OUT' will disappear; 4. Press the ON key to control the presence or absence of the waveform, the disappearance of OUT means that there is no output waveform, and the output is 0; 5. Power on and restart or ON key to turn on the output, and recalculate the number of pulses;
- ♥Application scenarios: 1. PWM signal generator, square wave rectangular wave signal generator. 2. It is used to generate square wave and rectangular wave signals to control DC motor or stepper motor driver; it is used for servo motor, stepper motor, electric gripper, replace PLC pulse, etc. 3.ZK-PP1K can be matched with drivers to realize dimming, speed regulation, control solenoid valves, etc., but cannot directly drive loads such as electric light motor solenoid valves, etc.

### ⭐⭐⭐⭐⭐ works perfectly – has full enclosure – good signal quality - to get instructions copy website
*by R***R on March 4, 2023*

works perfectly – has full enclosure – good signal quality - to get instructions copy website In reference to module: ZK-PP1K . The website photographs do not show that this module is actually totally enclosed within a box. If you are really good at cutting exact measurement perfect rectangular holes, then you can panel mount this using the side snap in clips. The product came in a tiny package with no instructions. To easily get the instructions I simply saved the web page as an *.pdf and then did some editing. This module works perfectly with good design and build quality. I will buy more of the other different offered modules.
