INSTRUCTION MANUAL
4. Explanation of Functions and Precautions
41. Input Voltage Range
Input voltage range is single phase 85265VAC (4763Hz) or 120340VDC.
Input voltage, which is out of specification, might lead unit damage. For cases where conformance to various
safeties required, described as 100240VAC (5060Hz).
Output derating is required for AC input voltage less than 90VAC.
42. Output Voltage Range
Output voltage is set at the rated value. Output voltage within the range specified can be adjusted by V.ADJ
trimmer. Output voltage range is within ±15% (48V : +10% / 15%) of nominal output voltage.
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 become unstable. To maintain
the output voltage stable, flow the output current, or remove the input of power supply until the output be
shut down, and then reinput. Please turn the trimmer slowly during the output voltage adjustment.
43. Inrush Current
Thyristor method is used for limiting the inrush current. Higher current may flow when input turn on interval
is short.
First inrush current and second inrush current flow.
Please select input switch and external fuse carefully.
44. Over Voltage Protection (OVP)
The OVP function is inverter shut down method and manual reset type. OVP function operates within 120145%
(48V : 115125%) 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. Or, use Remote ON/OFF reset on option model /R and /RFO only (Remote : OFF to
ON). In addition, the setting value of OVP is fixed and not adjustable. Never 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.
45. Over Current Protection (OCP)
Constant current limit 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. Delay Shut Down
This product have a delay shut down function provided to protect power supply and equipment at the time
when the output current exceeds maximum DC output current of specification. When the product operate
over current condition for more than 5 seconds, delay shut down function operates and the output will be shut
down.
To reset delay shut down, remove the input of power supply for a few minutes, and then reinput. Or, use
Remote ON/OFF control reset on option model /R and /RFO only ( Remote : OFF to ON).
Delay Shut Down Time value is fixed and not to be adjusted externally.
47. Over Temperature Shut Down
Over temperature shut down function is provided.
When ambient or internal temperature rises abnormally, over temperature shut down function operates and
output will be shut down. After shut down, remove the input and cool it down to reset over temperature shut
down, and then reinput. Over temperature shut down function operates at out of the specification area.
This function may not activate or cannot avoid power supply damage depending on the situation.

48. Output Ripple & Noise
The standard specification for maximum ripple value is measured according to measurement circuit specified
by JEITARC9131C. 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.

6. Wiring Method
(1) The output load line and input line shall be separated, and use all lines as thick and short as possible to make
lower impedance. The output load line and input line shall be twisted or use shielded wire to improve noise
sensitivity.
(2) Remote sensing lines and remote ON/OFF control lines shall be twisted and separated from the output lines.
(3) Noise can be eliminated by attaching a capacitor to the load terminals.
(4) The recommended wire type, torque and crimptype terminal :

Note 1 : When connecting some units, use of two pcs. of 0.8mm thick crimp
type terminal is recommended for input terminal.
Note 2 : For recommended wire type, refer to wire maker recommended
allowable current and voltage drop.
Especially for 12V models, output current is large.
Thick diameter wire is recommended.
Recommended wire type and crimptype terminal vary depending
on use conditions. Choice most appropriate wire type and
crimptype terminal by refering to wire maker recommended
allowable current and voltage drop.
Note 3 : Output terminal is possible to install on arbitrary surface by customer.
(Refer to Fig.1 and Fig.2 for reference.)
Recommended to install single surface at same time to attach terminal cover for safety.
At shipment condition, screw is installed on top side (Fig.1). When installing on front side, please
reverse position of screw and terminal cover (Fig.2).
Do not recommend install dual surface at same time. It may cause touch each screw and cannot attach
terminal cover.

7. The life expectancy
The life expectancy of the power supply is as follows.
The life expectancy is dependent on the lifetime of electrolytic capacitor or the fan.
The life expectancy is not a guaranteed value, please consider as a reference.
Do not use the product which passed over the life expectancy. There is a risk of unexpected output shutdown or
specifications may not be satisfied.
Please contact us for maintenance or exchange the product which passed over the life expectancy.
The life expectancy of power supply is calculated in condition of rated input voltage and 24hour continuous
operation.
Load (%) is percent of maximum output current in a rated output voltage.

8. External Fuse Rating
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.
RWS1000B : 20A
RWS1500B : 30A
9. Before concluding that the unit is at fault…
Before concluding that the unit is at fault, make the following checks.
(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 Remote ON/OFF control connector is not opened, when use Remote ON/OFF control function
(/R, /RFO).
(6) Check if the output current and output power does not over specifications.
(7) Audible noise can be heard when input voltage waveform is not sinusoidal wave.
(8) Audible noise can be heard during DynamicLoad operation.
(9) Ensure that large capacitor is not connected on the output side.
Please use within maximum capacitance shown below.
Please contact us, if connecting more than the following capacitance value.
