USING ATTENTIONS



Module will cause irreversible damage when in the state of the input reverse polarity.



Module will cause irreversible damage when in the long-term overload conditions.



Module will cause irreversible damage when out of the maximum input voltage range.



Add input capacitance Cin is helpful to improve the electromagnetic compatibility, recommend Cin use 47 uF-100uF of the electrolytic capacitors.



If the module connect to the digital circuits, please add the Cout、Cout1、Cout2.



If Cout, Cout1, Cout2 value is too high or lower ESR, it will cause the module instable,



The recommended value of Cout, Cout1, Cout2 should be 100 uF/A, the current here means the output current.

Raise the output Voltage

Down the output voltage



In dual and triple output modules, this application can just used in the main load(auxiliary load change together with the main load)
