Overvoltage Protection
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 higher is output, the output voltage is shut OFF, preventing
damage to the load due to overvoltage.
To reset the protection, turn OFF the input power for three minutes or
longer and then turn it back ON.

Precautions for Safe Use
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.
• The light ignition may possibly be caused. 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.
• Always select wire sizes suitable for at least 1.6 times the rated
current to prevent heating and ignition of wire materials due to load
abnormalities. Refer to the wiring manufacturer’s recommended
allowable current and voltage drop specifications for information
when selecting wiring materials.
• The current rating for the output terminal is 5A per terminal.
Make sure to use multiple terminals together if a current
exceeding the terminal rating is used.
• 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 6 for the model
numbers of the Input and Output Connectors.
Do not insert and remove any connector more than 20 times.
Installation Environment
• Avoid places subject to shock or vibration.
A device such as a contact breaker may be a vibration source. Set
the Power Supply as far as possible from possible sources of
shock or vibration.
• If the Power Supply is used in an area with excessive electronic
noise, be sure to separate the Power Supply as far as possible
from the noise and surge sources.
Ambient Operating and Storage Environments
• Store the product with ambient temperature −25 to 75°C, and
relative humidity 25 to 90%.
• The internal parts may occasionally be deteriorated or broken. Do
not use the product outside the derating range.
• Use the product where the relative humidity is 25 to 85%.
• Avoid places where the product is subjected to direct sunlight.
• Avoid places where the product is subjected to penetration of
liquid, foreign substance, or corrosive gas

• Install the Power Supply so that heat is effectively dissipated to
improve and maintain the reliability of the Power Supply over a
long period of time.
• The S8EA uses natural convection. Mount so that convection of
the air around the power unit can take place.
• The crosshatching indicates the allowable range for the mounted
metal part.
• 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.
• Depending on how the Power Supply is mounted, the heat
dissipating capacity may be reduced and cause deterioration to or
damage the 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.
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.
16
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 diodes as shown in the figure. Select
diodes with 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.

• 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.

Overload Protection
Ripple Noise Voltage
• 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.
Charging Batteries
When connecting a battery at the load, connect an overcurrentlimiting circuit and overvoltage protection circuit.
The specified standard for the ripple voltage noise was measured with
a measurement circuit that is based on JEITA standard RC-9131B.

In Case There Is No Output Voltage
A 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,
is applied to the input.
In case there is no output voltage, please check the following points
before contacting us:
• Checking the 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 S8EA series. Then turn it ON again to see if this
clears the condition.
Power Boost Function
• Do not allow the boost current to continue for more than 10
seconds. Also, do not let the duty cycle exceed the following
conditions. This may damage the Power Supply.
• Lessen the load of the boosted load current by adjusting the
ambient temperature and the mounting direction.
• Ensure that the average current of one cycle of the boost current
does not exceed the specified value. This may damage the Power
Supply.
