Features Automatic shutdown: the converter has various software protection mechanisms and the protection threshold is adjustable. When the working parameters of the module exceed the protection threshold, the output is automatically switched off. Multiple applications: the voltage converter board can be used as a normal buck or boost module with overcurrent protection; Used as a high performance LED constant current driver module; DIY a solar controller, battery charging. Safety protection: the input end of the power module has reverse polarity protection, which does not burn out when the connection is reversed. The output side is protected against electricity. No need to add countercurrent diodes when charging. Technical parameters: the buck boost converter has a low output ripple and can be equipped with a π filter. Thick heatsink, built-in buck and boost. Display contents: the LCD voltage regulator can display input or output voltage, output current, output power, output capacity and output time.
