4.Explanation of Function and Precautions
4-1. Input Voltage Range
Input voltage range is single phase 85-265VAC(47-63Hz). 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). 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 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.
To recovery from OVP, we need to turn off the input of power supply for a few minutes, and then re-input.

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)
(B)
(*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.
4-8. Parallel Operation
For parallel operation, method (B) is possible
(A) To increase the output current is not possible.

(B) To use as Back-up Power Supply
1. Adjust the output voltage of each power supply to be the same.
2. Set power supply output voltage higher by the forward voltage
drop (Vf) of diode.

4-9. Isolation Test
Isolation resistance between Output and
is more than 100MΩat 500VDC. For safety operation, voltage setting of DC isolation tester
must be done before the test. Ensure that the unit is fully discharged after the test.
4-10. Withstand Voltage Test
These products are designed to withstand 4kVAC between input and output, 2kVAC between input and
and 1.5kVAC between output
and
for 1 minute. When testing withstand voltage, set current limit of the withstand voltage test equipment to 20mA. The applied voltage
must be gradually increased from zero to the testing value and then gradually decreased for shut down. When timer is used, the power supply
may be damaged by high impulse voltage at timer switch on and off. Connect input and output as follows.
Input – Output: 4kVAC,

5-3. Mounting Method
Insert the spacer (Maxφ7mm) of height more than 8mm to lift the unit. And use all mounting holes for the unit installation. The vibration
spec is specified under this mounting condition. Keep enough space in the power supply surroundings and the upper area of components for
convection cooling
(1) Mounting Holes size:
4 holesφ3.5mm.

Instruction Manual
(2) Conditions to meet Isolation and Withstanding Voltage standard.
Keep 5mm space from the surfaces and sides of PCB. Especially, 8mm space is necessary from the solder surface. If the space is not
enough, the specification of isolation or withstanding voltage will not be satisfied.
(3)
(Protective Earth) should be connected to the earth terminal of the equipment. Also the mounting hole are should be connected to
the Chassis by metal spacer. If not, the conducted noise, radiation noise and output noise may increase. Please refer to below setup.
6. Wiring Method
(1) The output load line and input line shall be separated each other and twisted individually to improve noise.
(2) Use all lines as thick and short as possible to made lower impedance.
(3) Noise can be reduced by attaching a capacitor to the load terminals.
(4) For safety and EMI considerations, connect
with the terminal of protective earth of equipment firmly.
7. External Fuse Rating
Refer to the following fuse rating when selecting the external fuses that are to be used on input line. Surge current flows when line turns on.
Have to use slow-blow or time-lag type fuse, not fast-blow fuse. Fuse rating is considered by in-rush current value at line turn-on. Do not
select the fuse according to input current (RMS.) values under the actual load condition.
