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 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.
4-4. Over Voltage Protection (OVP)
The OVP function (Inverter shut down method, manual reset type) is provided. Please refer to its specification for OVP range. When OVP
triggers, the output will be shut down. 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.
Two methods to recovery form OVP:

Turn off the input of power supply for a few minutes, and then re-input.

Remote OFF, and then remote ON again. (Refer to 4-13.)
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, however
the outputs may be latched off when shorted condition happens. 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.
4-6. Output Ripple & Noise
The standard specification for maximum ripple value is measured according to measurement circuit specified as below. When load lines are
longer, ripple will becomes larger. In this case, electrolytic capacitor, film capacitor, etc. might be necessary to use across the load terminal.
The output ripple cannot be measured accurately if the probe ground lead of oscilloscope is too long.
4-7. Series Operation
For series operation, either method (A) or (B) is possible.
(A)
(*1)Please select a bypass diode with maximum forward current rating more than output load current. And maximum reverse voltage must
withstand each power supply output voltage.
(B)
