4. Explanation of Functions and Precautions
41. Input Voltage Range
Input voltage range is single phase 85264VAC (4763Hz) or 120370VDC.
Input voltage, which is out of specification, might lead unit damage. For cases where conformance to various
safeties required, described as 100240VAC (5060Hz).
In case of using input voltage, which is less than specification, output voltage might repeat start and stop.
Output derating is required for AC input voltage less than 90VAC (less than 100VAC for /C2 and /C2E).
Regarding the output derating, please see at “53. Output Derating according to Input Voltage”.
42. Output Voltage Range
Output voltage is set the rated value at shipment. Output voltage within +18%/10%（5V : +20%/10%,
12V : +25%/10%） can be adjusted by V.ADJ trimmer (except for /C2 and /C2E).
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 not change quickly. In this
case, flow the output current, or wait until the output voltage is stable, and then reinput. Please turn the
trimmer slowly during the output voltage adjustment.
43. Inrush Current
This series equipped Power thermistor to limit the inrush current. The higher current will flow at higher
ambient temperature or reinput condition. Please select input switch and fuse carefully with the high
temperature and reinput the power condition. The inrush current value is under cold start at 25℃ in the
specification. Regarding the external fuse, please see at “9. External Fuse Rating”.
44. Over Voltage Protection (OVP)
The OVP function is inverter shut down method and manual reset type. OVP function operates within125145%
(5V : 124146%, 12V : 133156%) of nominal output voltage.
When OVP triggers, the output will be shut down. To reset OVP, remove the input of power supply for a few
minutes, and then reinput. In addition, the setting value of OVP is fixed and not adjustable. Pay attention not to
apply 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.
45. Over Current Protection (OCP)
This series is 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 removed. Never operate the unit
under over current or shorted conditions, which may lead unit damage. OCP setting is fixed and cannot be
adjusted externally.
46. Output Ripple & Noise
The standard specification for maximum ripple value is measured according to measurement circuit specified
by JEITA RC9131B. 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 measure accurately if the probe ground lead of oscilloscope is too long.

1.Set the power supply output voltage higher by the amount of forward voltage drop (VF) of the diode.
2.Please adjust the output voltage of each power supply to be the same.
3.Please use within the specifications for output voltage and output power.
4.Please select a reverse current prevention diode with maximum forward current rating more than output

410. Withstand Voltage
This series is designed to withstand 3.0kVAC between input and output, 2.0kVAC between input and terminal
and 500VAC between output and terminal each for 1 minute. When testing withstand voltage, set current
limit of withstand voltage test equipment at 20mA (Output terminal : 50mA). The applied voltage must be
gradually increased from zero to 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 timing. Connect input and
output as follows.

Note 1 : DRJ15, DRJ30 have monolithic ceramic capacitor in secondary circuit to .
Some of the withstand voltage tester may generate high voltage at the matching with monolithic
ceramic capacitor and may cause the unit damage.
So, please check the waveform of applied voltage.
Note 2 : In case of using external noise filter, capacitance between "Input and " might be increased.
When testing withstand voltage between "Input and Output", there is a possibility exceeding withstand
voltage between "Output and " (500VAC). Please check the voltage between "Output and ".
If the voltage exceeding withstand voltage, please add external capacitor to
"Output and ". It can decrease the voltage.
On the other hand, no need to check the voltage in case of "Output and " is shorted.

7. The life expectancy
The life expectancy of the power supply is as follows.
The life of the power supply depends on the life of the builtin aluminum electrolytic capacitor.
The life expectancy is not a guaranteed value, please consider as a reference.
Please do not use the product which passed over the life expectancy.
There is a risk of unexpected output shutdown and specifications may not be satisfied.

The life expectancy of power supply is calculated in condition of rated input voltage and 24hour continuous
operation.
Load (%) is percent of maximum output power or maximum output current, do not exceed its derating of
maximum load.

Refer to the following fuse rating when selecting the external input fuse.
Surge current flows when input turn on. Use slowblow fuse or timelug fuse. Fastblow fuse can not be used.
Fuse rating is specified by inrush current value at input turn on.
Do not select the fuse according to actual input current (rms.) values.
DRJ15, DRJ30 : 2.5A
DRJ50, DRJ100 : 3.15A
10. Power supply mounting on DIN RAIL
DRJ series conforms to TS35 size of DIN standard, the width of mounting rail is 35mm.
101. Power supply mounting on DIN RAIL
Make sure input and output wire disconnected when mount power supply onto rail.
(1) Tilt the unit slightly rearwards, fit the unit over top hat rail.

(2) Press against the bottom front side for locking.
Shake the unit slightly to check the locking action.
102. Power supply removal from DIN RAIL
Switch main power off and disconnect your system from the supply network. Push the button on the rear
upper edge of the unit or move the removal hole on the rear down edge downwards by rotating screw driver.
Gently lift lower front edge of the unit (tipping) and remove it.
In the case of mounting (B), reverse position from mounting (A).

11. Before concluding that the unit is at fault…
(1)Check if the rated input voltage is connected.
(2)Check if the wiring of input and output is correct.
(3)Check if the wire size is not too thin.
(4)Check if the output voltage control (V.ADJ) is properly adjusted.
(5)Check if the output current and output power does not over specifications.
(6)Audible noise can be heard when input voltage waveform is not sine wave.
(7)Check if DynamicLoad operation is set.
Audible noise can be heard and output voltage variability might increased during DynamicLoad operation.
Please use based on enough evaluation.
(8)Ensure that large capacitor is not connected on the output side.
Please use within maximum capacitance shown below.
If connecting more than the following capacitance value is required, please contact us for details.
