condensation on the product or deterioration.  
· For long-term storage period, we recommend to use within 2 years after receiving the product.  
There is tendency that the leakage current of an aluminium electrolytic capacitor may increase when stored  
without using for a long time.  
This phenomenon can be improved by applying voltage to the aluminum electrolytic capacitor to reduce the  
increased leakage current through the self-recovery effect of the electrolyte.  
For reference, before using products that have been stored for a very long time, please warm-up first for 30  
minutes or more without taking load.

6. Explanation of Functions and Precautions  
6-1. Input Voltage Range  
Input voltage range is single phase 85-265VAC (47-63Hz) or 120-340VDC.  
Input voltage, which is out of specification, might lead unit damage. For cases where conformance to various  
safeties required, described as 100-240VAC (50-60Hz).  
Output derating is required for AC input voltage less than 90VAC.  
6-2. Output Voltage Range  
Output voltage is set at the rated value. Output voltage within the range specified can be adjusted by V.ADJ  
trimmer. Output voltage must be within spesification.  
Turning the trimmer clockwise, the output voltage will be increased. Take note when the output voltage is  
increased. Excessively, over voltage protection (OVP) function may trigger and voltage will be shut down.  
Furthermore, when increasing the output voltage, reduce the output current as not to exceed the maximum  
output power.  
When the trimmer turns quickly at no load condition, the output voltage might become unstable. To maintain  
the output voltage stable, flow the output current, or remove the input of power supply until the output be  
shut down, and then re-input. Please turn the trimmer slowly during the output voltage adjustment.
