Notice:

This is a voltage step-down conversion module. The following conditions must be followed when using it.:
1 The input voltage cannot be greater than the nominal voltage, otherwise the module will be burned out.
2 The input power must be greater than the output power, otherwise the output voltage will be less than the nominal voltage.
3 The output load cannot be greater than the nominal load, otherwise the output voltage will be less than the nominal voltage.
4 This is a high-power module. Be sure to use thick enough wires and make good contact.
