AUTOMATIC SHUTDOWN: The converter features multiple software protection mechanisms with adjustable protection thresholds. If the module's operating parameters exceed the set limits, the output will automatically shut down. DISPLAY CONTENT: The LCD voltage regulator displays input and output voltage, output current, output power, output capacity, and output time. SAFETY PROTECTION: The power module includes reverse connection protection at the input to prevent damage during incorrect installation. The output is protected against reverse current, eliminating the need for additional diodes when charging. MULTIPLE APPLICATIONS: This voltage converter board can function as a buck or boost module with overcurrent protection, serve as a high-power LED constant current driver, or be used to create a solar controller or battery charging system. TECHNICAL PARAMETERS: The buck-boost converter produces low output ripple and is compatible with a π filter. It features a thick heatsink and integrates both buck and boost circuitry.
