4-1-1. Input Voltage vs Output Derating
Output derating is required when the power supply operate below 100VAC input. Refer to table below for details.

4-2. Output Voltage Range
Output voltage is set the rated value at shipment. V.ADJ trimmer (VR51) can adjust 5V 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 triggerd 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. These products are Power Thermistor method so that higher 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 is typical value under cold start at 25 ℃ in the specification.
4-4. Over Voltage Protection (OVP)
The OVP function (Inverter shut down method, manual reset type) is provided for +5V and +12V (+15V). OVP range refers to the
specification. When OVP triggers, all outputs will be shut down. To reset OVP, remove the input of power supply for a few minutes, and then
re-input. In addition, the setting value of OVP is fixed and not adjustable. Pay attention not to apply higher voltage externally to the output
terminal to avoid unit failure. In case of inductive load, put protective diode in series to the output power line.
4-5. Over Current Protection (OCP)
These products provide the Hiccup mode with automatic recovery .OCP function operates when the output current exceeds 105% of
maximum DC output current of specification. The outputs will be automatically recovered when the overload condition is canceled. Never
operate the unit under over current or shorted conditions for more than 30seconds, which may leads damage or insulation failure. OCP setting
is fixed and not to be adjusted externally.
