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:

 


Q1 : Why output voltage is less than the nominal voltage


A1: 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


 


Q2 : Why is the negative voltage not output or the output too low?


A2 : The negative voltage cannot be used alone. When using a negative voltage, the same load must be connected at the positive voltage terminal.
