Feature: 1. AUTOMATIC SHUTDOWN: Converter has a variety of software protection mechanisms, and the protection threshold is adjustable. When the working parameters of the module exceed the protection threshold, the output is automatically shut down 2. DISPLAY CONTENT: LCD voltage regulator can display input or output voltage, output current, output power, output capacity, output time 3. SAFETY PROTECTION: The input end of the power module has prevent reverse connection protection, which will not burn out during reverse connection. The output end is protected against counter current. No need to add counter current diodes when charging 4. MULTIPLE APPLICATIONS: The voltage converter board can be used as a regular buck or boost module with overcurrent protection Used as a high power LED constant current driver module DIY a solar controller, battery charging 5.
