The 9744 Voltage Step Down 6–40V CV-CC 300W is a high-power adjustable DC-DC buck converter module designed to convert a DC input voltage into a lower regulated output voltage.
It supports CV/CC operation, meaning constant voltage and constant current / current limiting adjustment, making it suitable for bench power supplies, battery charging, high-power LED driving, electronics projects, Arduino / DIY applications, robotics and automation systems.
The input voltage range is DC 6–40V, while the output voltage can be adjusted from approximately DC 1.2V to 36V, always below the input voltage. The maximum rated power is typically 300W, with output current up to 20A, provided that adequate cooling and proper operating conditions are used.
