MTBF stands for Mean Time Between Failures, which is calculated according to the probability of accidental device
failures, and indicates reliability of devices.
Therefore, it does not necessarily represent a life of the product.
The life expectancy indicates average operating hours under the ambient temperature of 40°C and a load rate of 50%.
Normally this is determined by the life expectancy of the built-in aluminum electrolytic capacitor.

Overload Protection
The Power Supply is provided with an overload protection function
that protects the power supply from possible damage by overcurrent.
When the output current rises above 105% min. of the rated current,
the protection function is triggered, decreasing the output voltage.
When the output current falls within the rated range, the overload
protection function is automatically cleared.

Overvoltage Protection
15-/35-/50-/100-/150-W Models
Consider the possibility of an overvoltage and design the system so
that the load will not be subjected to an excessive voltage even if the
feedback circuit in the power supply fails. When an excessive voltage
that is approximately 130% of the rated voltage or more is output, the
output voltage is shut OFF, preventing damage to the load due to
overvoltage. Reset the input power by turning it OFF for at least seven
minutes and then turning it back ON again.

If an excessive current flows for 5 s or more, the output will be turned

Note: 1. When a load is connected that has a built-in DC-DC

converter, the overload protection may operate at startup
and the power supply may not start.
2. Internal parts may occasionally deteriorate or be damaged
if a short-circuited or overcurrent state continues during
operation.
3. Internal parts may possibly deteriorate or be damaged if the
Power Supply is used for applications with frequent inrush
current or overloading at the load end. Do not use the Power
Supply for such applications.

Note: Do not turn ON the power again until the cause of the

Overheat Protection
600-W Model
If the internal temperature rises excessively as a result of fan failure
or any other reason, the overheat protection circuit will be triggered to
protect the internal parts and simultaneously the protection-ON alarm

Mounting
• Take adequate measures to ensure proper heat dissipation to
increase the long-term reliability of the Product.
•
Be sure to allow convection in the atmosphere around devices when
mounting. Do not use in locations where the ambient temperature
exceeds the range of the derating curve. (except 600 W)
• The S8JX-@60024@ is designed to radiate heat by means of
forced air-flow. Do not cover the air holes (provided at fan mounted
side and the opposite side) to have enough air-cooling.
• The screws must not protrude more than 8 mm inside the Power
Supply when screw holes provided on the chassis are used. (300
W, 600 W)
Mounting screw tightening torque (recommended value) : 0.54 N·m.
• Rear mounting is possible using provided mounting bracket.
• When cutting out holes for mounting, make sure that cuttings do
not enter the interior of the Products.
• Improper mounting will interfere with heat dissipation and may
occasionally result in deterioration or damage of internal parts. Use
the standard mounting method only.
• The internal parts may occasionally deteriorate and be broken due
to adverse heat radiation. Do not loosen the screw on the side face
of the main body.
• When mounting two or more Power Supplies side-by-side, allow at
least 20 mm spacing between them.
• Provide a space of at least 20 mm back and forth when mounting
300-W and 600-W models as well.
• Use the metal plate as the mounting panel.

Wiring
• Connect the ground completely. A protective earthing terminal
stipulated in safety standards is used. Electric shock or malfunction
may occur if the ground is not connected completely.
• Minor fire may possibly occur. Ensure that input and output
terminals are wired correctly.
• Do not apply more than 75 N force to the terminal block when
tightening it.
• Be sure to remove the sheet covering the Product for machining
before power-ON so that it does not interfere with heat dissipation.
• Use the following material for the wires to be connected to the
S8JX to prevent smoking or ignition caused by abnormal loads.

Installation Environment
• Do not use the Power Supply in locations subject to shocks or
vibrations. In particular, install the Power Supply as far away as
possible from contactors or other devices that are a vibration
source.
• Install the Power Supply well away from any sources of strong,
high-frequency noise and surge.
Ambient Operating and Storage Environments
• Store the Power Supply at a temperature of −25 to 65°C and a
humidity of 25% to 90%.
• The Internal parts may occasionally deteriorate or be damaged.
Do not use the Power Supply outside the derating range (i.e., the
area shown by shading A in the derating curve diagram on
page 9.)
• Use the Power Supply at a humidity of 25% to 85%.
• Do not use the Power Supply in locations subject to direct sunlight.
• Do not use locations where liquids, foreign matter, or corrosive
gases may enter the interior of the Product.
Overload Protection
• Internal parts may possibly deteriorate or be damaged if a shortcircuited or overload state continues during operation.
• Internal parts may possibly deteriorate or be damaged if the Power
Supply is used for applications with frequent inrush current or
overloading at the load end. Do not use the Power Supply for such
applications.
Charging a Battery
When connecting a battery at the load, connect an overcurrent
limiting circuit and overvoltage protection circuit.
Output Voltage Adjuster (V.ADJ)
• The output voltage adjuster (V.ADJ) may possibly be damaged if it
is turned with unnecessary force. Do not turn the adjuster with
excessive force.
• After completing output voltage adjustment, be sure that the output
capacity or output current does not exceed the rated output
capacity or rated output current.
DIN Rail-mounting
To mount the Power Supply to a DIN
Rail, pull down the rail stopper until
you hear it clicks open, hook portion
(A) of the Power Supply onto the DIN
Rail, press the Power Supply in
direction (B), and then push up the rail
stopper to lock the Power Supply in
place.
To dismount the Power Supply, pull
down portion (C) with a flat-blade
screwdriver and pull out the Power
Supply.

Note: 1. If the load is short-circuited, a reverse voltage will be
generated inside the Power Supply. If this occurs the Power
Supply may possibly deteriorate or be damaged. Always
connect a diode as shown in the figure. Select a diode
having the following ratings.

Dielectric strength (V
Forward current (I
RRM)Twice the rated output voltage or above
F)Twice the rated output current or above
2. Although Products having different specifications can be
connected in series, the current flowing through the load
must not exceed the smaller rated output current.
Parallel Operation
15-/35-/50-/100-/150-W Models
The Product is not designed for parallel operation.
Parallel Operation
Incorrect
300-/600-W Models
Parallel operation is possible under 80% of the rated value.
• To operate in parallel, set the switch to the "PARALLEL" side.
• The length and thickness of each wire connected to the load must
be the same so that there is no difference in voltage drop value
between the load and the output terminals of each Power Supply.
• It is desirable to set the same value on the voltage adjuster of each
Power Supply.

In Case There Is No Output Voltage
The possible cause for no output voltage may be that the overcurrent
or overvoltage protection has operated. The internal protection may
operate if a large amount of surge voltage such as a lightening surge
occurs while turning ON the Power Supply.
In case there is no output voltage, please check the following points
before contacting us:
• Checking overcurrent protected status:
Check whether the load is in overcurrent status or is shortcircuited. Remove wires to load when checking.
• Checking overvoltage or internal protection:
Turn the power supply OFF once, and leave it OFF for at least
7 minutes. Then turn it ON again to see if this clears the condition.
Switching the AC Input Voltage between 100 and 200 VAC
300-/600-W Models
The input voltage can be switched between 100 and 200 V by shorting
or opening the input voltage selection terminals. Set the required
voltage as shown below. (The voltage is factory-set to 200 V.)

Fan Replacement
600-W Model
The service life of the fan is approximately 50,000 hours (at 25°C).
The service life varies, however, depending on the ambient
temperature or other surrounding environmental conditions such as
dust. As a preventive maintenance measure, replace the fan within
approx. two years if it is used at an ambient temperature of 40°C.
Fans are available as replacements.
Fan Set:
Fan (above), four M4 x 35 sems screws, instruction sheet, and packing case
