Features:
1. Wide range of applications:The adjustable step-down power supply module is suitable for a variety of applications, including high-power LED constant current drive, lithium battery charging, battery charging for different voltage levels, solar panels, wind generators, and more.2. High output current:With a maximum output current of 20A and long-term output current of 15A, this module can handle high-power applications with ease. However, it is important to note that when the power tube temperature exceeds 65 degrees, it is recommended to add a fan to dissipate heat and derate use for high voltage output.3. Continuously adjustable output voltage:The output voltage can be continuously adjusted from 1.2-35VDC, making it ideal for applications where the input voltage is higher than the output voltage and cannot be boosted.4. High conversion efficiency:With up to about 96% efficiency, this module is highly efficient and can help save energy and reduce costs. The efficiency is related to dropout voltage and operating environment.5. Compact size and easy installation:The module is small in size (60*53*30MM) and easy to install with a terminal block wiring method. It also comes with output short-circuit protection for added safety. Overall, the adjustable step-down power supply module is a versatile and reliable solution for a wide range of applications, offering high output current, continuously adjustable output voltage, high conversion efficiency, and easy installation in a compact size.
