Reference Value
Item Value Definition
Reliability (MTBF) 135,000 hrs min. MTBF stands for Mean T ime 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.
Life expectancy 8 yrs. min. 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 load and the power supply from possible damage
by overcurrent. When the output current rises above a set value
(105%
of the rated output current for all models, 101% of the rated
output current for 90-W model), 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.
When
using the 7.5-W single-output models within the input voltage
range between 90 and 1 10 VDC, the protection function will operate
at a current of 95% of the rated load current.
When using the 90-W model at an ambient temperature exceeding
25°C, the protection function will operate at a current of 92% of the
rated load current.

When Using ±Output Models
The +V output detects the total output power (+V output and -V out -

protection varies depending on the -V output state. The -V output

triggers the short-circuit protection.
Overvoltage Protection
(S82K-24024T Models Only)
The Power Supply is provided with an overvoltage protection func -
tion
that protects the load and the Power Supply from possible dam -
age

ue,
the protection function is triggered, shutting of f the output volt -

Operation
Undervoltage Alarm Indicator and Output Function
(All Models Except for S82K-24024/P24024)
If the output voltage at the output terminal drops to 75% to 90% of the rated voltage, the red indicator of the S82K (DC LOW indicator) will be lit. In
the case of the S82K-10024/24024T , a voltage drop alarm will be output via the relay available in the models (DC LOW output).
Note: This function detects the voltage at the output terminal of the Power Supply . T o check the precise output voltage, measure the voltage
at the terminal of the load.

(see note 2)
Green: DC ON
Red: DC LOW
If the voltage at the output terminal is more than 90%
of the rated voltage, the green indicator will be lit.

(see note 1)
If the voltage at the output terminal is 75% to 90%,
the red indicator will be lit.

If the voltage at the output terminal is 0 V , both the
green and red indicators will not be lit.
Note: 1. The more the voltage at the output terminal drops, the darker both the green and red indicators will be.
2. The relay contacts have a capacity of 0.1 A at 24 VDC.

Precautions
Caution
Be sure to connect the grounding line. Not doing so may result
in electric shock.
WARNING
Do not attempt to disassemble the Power Supply or touch its
internal parts while power is being supplied. Doing so may re -
sult in electric shock.
Do
not touch the terminals of the Power Supply within one min -
ute
after power has been turned OFF . Doing so may result in
electric shock due to a residual voltage.
Do not touch the Power Supply Unit while power is being sup -
plied
or immediately after power has been turned OFF . Doing
so may result in a skin burn due to high temperature of the
Power
Supply .
Mounting
T o improve and maintain the reliability of the Power Supply over a
long period of time, adequate consideration must be given to heat
radiation.
The
Power Supply is designed to radiate heat by means of natural
air-flow. Therefore, mount the Power Supply so that air flow takes
place
around the Power Supply .
Air
When mounting two or more Power Supplies side-by-side, allow at
least 10 mm spacing between them, as shown in the following il-
lustration.
Forced
air-cooling is recommended.
10 mm min.
Short bar
To mount the Power Supply on a DIN track, hook portion (A) of the
Power Supply to the track and press the Power Supply toward direc -
tion (B).
(A)
(B)
To dismount the Power Supply, pull down portion (C) with a flat-
blade
screwdriver and pull out the Power Supply .

mm min.
Track stopper
When tightening the terminals, do not tighten the terminal block to a
torque greater than 75 N.
Selection of 100 or 200 VAC Input Voltage
(S82K-09024/-10024/-24024/-24024T)
Select a 100 V or 200 V input by shorting or opening the Input V olt-
age
Selector T erminals, as shown in the following diagram.
The default setting is 200 V .
100 V Input

Use the short bar to short-circuit
terminals 4 and 5.
Remove the short bar.
Generating Output Voltage (±)
An output of ±can be generated by using two Power Supplies as
shown below, because the Power Supply produces a floating out-
put.

When connecting the Power Supplies in series with an operation
amplifier, connect diodes to the output terminals as shown by the
dotted lines in the figure. No diodes are required with S82K
90-W/100-W/240-W
models.

Wiring
Carefully wire the input/output terminals while paying attention to
their
polarities so as to prevent incorrect wiring.
Battery Charging
When connecting a battery to the load, install an overcurrent limit
circuit
and overvoltage protection circuit.
Series Operation
S82K 90-W/100-W/240-W model can be operated in series.
It must be noted that the + output of the 7.5-W dual output model
cannot
be connected in series to its – output.

Parallel Operation Precautions
•The length and thickness of each wire connected to the load
must
be the same so that there is no dif ference in voltage drop
value between the load and the output terminals of each Power
Supply.
•Adjust the output voltage of each Power Supply so that there will
be no dif ference in output voltage between each Power Supply .
•If the 240-W Power Supply is used in single operation under the
parallel operation setting, the overcurrent protection will be
actuated at an output of 90% to 95% (in current), and will not
allow
a 100% output.
•If the 240-W Power Supplies are used in parallel operation under
the single operation setting, one of them will operate at 110%
output,
causing severe heat derating and shortening the service
life.
Minimum Output Current
The minimum output current of the S82K-00727 and S82K-00728 is
restricted by the output voltage and control method.
Note: All the outputs of the S82K-00727 and S82K-00728 are
controlled
by the +V output. If the +V output current falls to
10% or less of the rated output, the –V output voltage may
drop.
Operating and Storage Environments
Do not use or store the Unit in the following places, otherwise the
Unit
may malfunction or the characteristics of the Unit may deterio -
rate.
•Locations subject to direct sunlight.
•Locations subject to ambient operating temperatures outside the
range indicated by the derating curve.
•Locations subject to ambient operating humidity outside the
range
of 25% to 85%.
•Locations subject to condensation as the result of severe
changes
in temperature.
• Locations subject to ambient storage temperatures outside the
range of –25 ° C to 65 °C.
• Locations subject to corrosive or flammable gases.
• Locations subject to dust (especially iron dust) or salts.
• Locations subject to shock or vibration.
• Locations subject to exposure to water , oil, or chemicals.
