Attention :

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
