TOFKE PWM Frequency Meter 1 Channel Pulse Generator LED Display Frequency Module 1Hz 160kHz Adjustable Duty Ratio 0~100 Square Wave Rectangular Wave Signal Generator 1 CH

1. Working voltage: DC4 ~ 30V; 2. Frequency range: 1Hz ~ 160KHz; 3. Frequency accuracy: the accuracy in each range is about 2%; 4. Signal load capacity: the output current can be about 5 ~ 30ma; 5. Output amplitude: PWM amplitude equal to the supply voltage; PWM output, can set the frequency, duty cycle The frequency is divided into four ranges, automatic switching: 1.XXX (without decimal point): 1Hz~999Hz, unit 1Hz 2.X.XX (decimal point in hundreds): Value is from 1.00KHz to 9.99KHz in 0.01KHz 3.XX.X (decimal point in ten digits): The value is 10.0KHz~99.9KHz, the unit is 0.1KHz 4.X.X.X. (full decimal point): Value 100KHz~160KHz, unit 1KHz E.g: 100 represents 100Hz 1.00 means 1.00KHz 10.0 means 10KHz 1.0.0. means 100Khz Instruction: Setup process: 1. Press the SET button, the frequency parameter flashes, and the frequency is set by the UP or DOWN button. 2. Press the SET button, the duty cycle parameter flashes, and the duty cycle is set by the UP or DOWN button. 3. Press the SET button to exit the setting. 4. Press and hold the UP button and DOWN button to increase or decrease quickly. 5. Data is automatically remembered, and all setting parameters are saved after power down. Application: 1. Used as a square wave signal generator, generate square wave signal for experimental development and use; 2. Used to generate a square wave signal that controls the motor driver; 3. Generate adjustable pulse for MCU use; 4. Generate adjustable pulse, control the relevant circuit (PWM dimming speed and other applications).
