Steps of use: 1.
1.Wiring:IN+ is input positive, IN- is input negative; OUT+ is output positive, OUT- is output negative.
2.Connect the connecting wire between the module and the power supply first, and then power on. Remember! Remember! (If the input side of the wiring with electricity, it is easy to fire phenomenon, especially when the input power supply voltage is high, and even burn the module's pads).
3. After selecting the appropriate power supply, use a multimeter or voltmeter to measure whether the output voltage of the module is consistent with the voltage required by the equipment.
4. Connect the electrical equipment or (load) to the output of the module.
Caution.
1.This is a step-down power module, so please keep the input at least 4.0V higher than the output.
2.Input and output are not isolated for safety and reliability.
