PWM Signal Generator Module
Module that allows you to generate PWM pulses from 1 Hz to 150KHz at a voltage between 3.3V and 30V. You can use this module for motor control, pwm signal generation, pwm signal lamp or speed control etc. You can use it in operations.
Technical Specifications:
- LCD display showing frequency and duty cycle
- Voltage Range - DC 3.3V-30V
- Frequency range
- Normal mode: 1Hz ~ 150KHz
- Sensitive mode: 1hz ~ 15khz
- Frequency accuracy: 2%
- Duty cycle accuracy
- 1% in normal mode
- 0.1% in precision mode
- Duty cycle range - 0.00% - 100%
- Output Current - Approx. 5-30mA
- Dimensions - 79x43x37mm
- Temperature Range - -40℃ ~ 85℃
- Humidity -0% ~ 95% relative humidity
A typical workflow is as follows:
- Connect to power source
- Normal press the rotary knob for 10 seconds to change mode and Sensitive mode
- Rotate the knob to set the frequency and change the value by turning the knob
- Press the rotary knob for 2 seconds to set the duty cycle
- Press and hold for 5 seconds to lock the set parameters
There is an interesting way to display frequencies at 100KHz or higher:
- "100" indication indicates that the PWM output frequency is 100Hz
- '1.91' indication indicates that the PWM output frequency is 1.91KHz
- '52.1' indication indicates that the PWM output frequency is 52.1KHz
- In the '1.3.4' indicator, the PWM output frequency is 134KHz;
