Input Voltage Derating Curve
Overvoltage Protection
For 50, 100, 150, and 240-W models, check the derating
characteristics for the input voltage before using the Power Supply.
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 three
minutes and then turning it back ON again.

The overload protection circuit will automatically reduce the output

When a drop of output voltage is detected, the voltage is output to the
outside by a transistor (DC LOW) (The output is OFF when the output
voltage is low). The detection voltage is set approximately 80% (75 to
90%) of the rated output voltage.
Note: 1. Transistor output: Open collector
30 VDC max., 50 mA max. ON: Residual voltage 2 V max.,
OFF: Leakage voltage 0.1 mA max.
2. The undervoltage alarm function monitors the voltage of the
output terminal of the power supply unit.
To check the accurate voltage condition, measure the
voltage of the load side.
3. If the setting voltage is set to 90% or less of the rated
voltage, the undervoltage alarm function may operate.

insert 1.5 kΩ as the current limiting resistor R.
2. Reverse connection of the connector may cause damage
on the internal parts.
3. The +RC and -RC terminals are the secondary circuit of the
power supply. Use an SELV output power supply for an
external power supply. The remote control circuit is
insulated from the secondary output of the power supply
(functional insulation).

22
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.
• Be sure to remove the sheet covering the Product for machining
before power-ON so that it does not interfere with heat dissipation.
• Use a wire diameter of at least 1.6 times the diameter that is
required for the rated current to prevent heating and ignition of wire
materials due to load abnormalities. Refer to the recommended
allowable current, voltage drop, and other specifications from the
manufacturer of the wires to select suitable wiring materials.
• The current rating of each output terminal is 2 A for -CN1
models and it is 5 A for all other models. If more than the
terminal current rating will flow, use two or more terminals
together.
• Use wiring materials with a UL recognized temperature of 60°C
min. or 60°C/75°C min.
• Use wiring materials with copper conductors.
• Refer to Input and Output Connectors on page 12 for the model
numbers of the input and output connectors. Do not insert and
remove any connector more than 20 times.
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 75°C and a
humidity of 25% to 90%.
• The Internal parts may occasionally deteriorate or be damaged.
Do not use the Power Supply beyond the operating temperature
range for the installation direction.
• 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 1 in the derating curve diagram.)
• 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.

Precautions for Correct Use
Mounting
Output Voltage Adjuster (V.ADJ)
Default Setting: Set at the rated voltage
Adjustment Range : The output voltage can be adjusted to ±10% of
the rated voltage with the voltage output adjuster
(V.ADJ) on the front panel. Turning clockwise
increases the output voltage, and turning
counterclockwise decreases the output voltage.
• 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.
• Adjusting the output voltage adjuster (V.ADJ) may cause the
output voltage to exceed the voltage range. When adjusting the
output voltage, check the output voltage of the Power Supply and
be sure that the load is not destroyed.

• Take adequate measures to ensure proper heat dissipation to
increase the long-term reliability of the Product.
• The S8EX-series are designed to radiate heat by means of natural
air-flow. Be sure to allow convection in the atmosphere around
devices when mounting.
• The shaded portions indicate the allowable range of the metal
mounting parts.
• When mounting, use the mounting holes in the board and spacers
to mount at least 8 mm off the board. This a clearance of 4 mm
space is necessary to satisfy the insulation and withstand voltage
standards.
• Metal plate is strongly recommended as the mounting panel.
Note: 1. Do not subject the board to stress such as twisting, bending,
or shock. This may cause failure or deterioration.
2. During assembly, do not subject the lead feet or surface
mounted parts to stress. This may cause failure or
deterioration.
• Do not allow cuttings to enter the Power Supply during installation.
• Depending on how the Power Supply is mounted, the heat
dissipating capacity may be reduced and cause deterioration to or
damage internal components.
• The internal parts may occasionally deteriorate and be broken due
to adverse heat radiation. Do not loosen the screws on the Power
Supply.
Two power supplies can be connected in series. The (±) voltage
output can be accomplished with two Power Supplies.

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.
Type
Schottky Barrier diode
Dielectric strength (VRRM)
Twice the rated output voltage or above
Forward current (IF)
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
In Case There Is No Output Voltage
The Product is not designed for parallel operation.
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
3 minutes for S8JX-P series. Then turn it ON again to see if this
clears the condition.

Use the same model for Power Supplies A and B.
• Type: Schottky barrier diode
• Dielectric strength (VRRM): Rated output voltage of the Power
Supply or higher
• Forward current (IF): Twice the rated output current of the Power
Supply or higher
• Set the output voltages of Power Supplies A and B higher to
compensate for the decrease of the forward voltages (VF) of diodes
D1 and D2. Also, there will be a power loss equivalent to the output
current (Iout) of the Power Supply multiplied by the forward voltage
(VF) of the diode. Therefore, cooling will be required to keep the
temperature of the diodes lower than the catalog value.
• There will be a power loss caused by load power and diodes. Be
sure not to exceed the rated power (rated output voltage times
rated output current) of each Power Supply.
Power Boost Function
• Do not allow the boost current to continue for more than the time
given in the following figure (t1). Also, do not let the duty cycle
exceed the following conditions. This may damage the power
supply.
• Lessen the load of the boost load current by adjusting the ambient
temperature and the mounting orientation.
• Ensure that the average current of one cycle of the boost current
does not exceed the specified value. Doing so may cause the
Power Supply to fail.

Overload Protection
• Internal parts may possibly deteriorate or be damaged if a
shortcircuited, overload or boost load 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.
