Operating Instructions:

🪶 Connect the VCC pin to a DC supply within the range of 7V to 40V. The red indicator light will illuminate to confirm that the module is receiving power. For frequency and duty cycle adjustments:

1. Connect the OUT interface to the positive input terminal of your oscilloscope, and the GND pin to the negative terminal.
2. Use potentiometer R5 to adjust the duty cycle and R6 to modify the frequency. It is recommended to set the output frequency above 700Hz for optimal performance.
3. Once the desired frequency and duty cycle are achieved, you can connect the OUT pin directly to the positive input terminal of your driving circuit while connecting GND to its negative terminal.

🏆 This PWM Controller Module is designed for those who seek efficient and effective solutions in power management and control systems. With its extensive features and adaptability, the TL494 SG3525 module is your go-to choice for a multitude of electronic applications.
