This is a DC-DC voltage converter module,Must be noted when using:

1 Input voltage can not be greater than the maximum input range

2 Output power can not be greater than the maximum load for a long time

3 Input power must be greater than the output power, because the power consumption of the module itself



Q & A:

Q : Why output voltage is less than the nominal voltage

A : Input power supply power is too low.Test the input voltage with a multimeter,a t this time of the input voltage is very low



Different power supplies have different output capabilities:
