It includes a clear backlit LCD for easy operation, supports duty cycles from 0-100%, and outputs signals up to the supply voltage with less than 30mA load capacity. Compact and robust, it’s designed for professional use in motor control, automation, and industrial signal generation. ## Description Product description 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. Output signal amplitude: amplitude is equal to the supply voltage. PWM mode - frequency (continuous), duty cycle. Note that the number of pulses cannot be set in this mode, and the pulse is always sent; PULSE mode - positive pulse width time, negative pulse width time, delay start time, and number of pulses are adjustable. Low Consumption Working Voltage: DC 3.3-30V, with anti-reverse protection. Low power consumption, fast conductivity and high safety Backlight Color Screen Size:79mm*43mm*30mm product weight: 40g. Clear backlight LCD display and user-friendly interface. Insulation material Frequency range: 1Hz~150KHz, accuracy about 1%. Insulation material, flame retardant, high temperature resistant, not easy to age Compact and convenient signal loading capacity:less than 30mA. Small, convenient and powerful, it is enough for the maintenance industry Review: Worked perfect - Worked perfect to control a treadmill motor by pwm 20hrtz signal to board then duty cycle controls speed. Very happy Review: Only 2v amplitude - While it does produce a square wave of the desired frequency, the duty cycle is invented and the max amplitude is just under 2v. The v- and v+ pins only offset the signal, not increase the amplitude of the signal. ## 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. - ►【Product Specifications】: Working voltage DC 3.3-30V; frequency range 1Hz-150kHz; duty ratio range 0-100%; number of pulse 1-9999 or infinite.Signal carrying capacity: <30mA; output signal secondary value: the secondary value is equal to the supply voltage. - ►【Features】:Dual mode: the function signal generator has 2 modes, PWM mode (default) & pulse mode.Easy to operate: the signal generator can control start or stop, it can also connect the external switch to control the output signal ON/OFF. - ►【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】: 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. ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.1 out of 5 stars 18 Reviews | ## Images ![Pwm Signal Generator,Dual Mode Function Frequency Generator Adjustable 1-150kHZ Pulse Square Rectangular Wave Signal Module Driver Controller LCD Display with Case - Image 1](https://m.media-amazon.com/images/I/61auVLO1c-L.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worked perfect *by J***S on September 10, 2023* Worked perfect to control a treadmill motor by pwm 20hrtz signal to board then duty cycle controls speed. Very happy ### ⭐ Only 2v amplitude *by R***O on April 2, 2021* While it does produce a square wave of the desired frequency, the duty cycle is invented and the max amplitude is just under 2v. The v- and v+ pins only offset the signal, not increase the amplitude of the signal. ### ⭐⭐⭐⭐⭐ Did as advertised *by L***E on April 16, 2021* I used it to control a treadmill DC motor on my home made 72" belt sander it worked as intended.
