4 Explanation of Function and Precautions
4-1. Input Voltage Range
Input voltage range is single phase 85-265VAC(47-63Hz). Never operate the unit out of the specified input voltage range to
avoid unit failure. For cases where conformance to various safeties required, input voltage range will be 100-240VAC (50-
60Hz). If input voltage is less than 115VAC, output power need to be derated.

4-2. Output Voltage Range
Output voltage is set the rated value at shipment. V.ADJ trimmer (VR51) can adjust the output voltage within the range.
Output voltage range refers to the specification. To turn the trimmer clockwise, the output voltage will be increased. Take
note when the output voltage is increased excessively, over voltage protection (OVP) function may be triggered and voltage
will be shut down. Furthermore, when increasing the output voltage reduce the output current so as not to exceed the
maximum output power.
4-3. Inrush Current
These products equipped Power thermistor to limit the inrush Current. Higher inrush current will flow at higher ambient
temperature or re-input condition. Please select input switch and fuse carefully with the high temperature and re-input the
power condition. The Inrush Current value is under cold start at 25
℃
in the specification.
