Overload Protection
50- to 300-W Models
The Power Supply is provided with an overload protection function
that protects the load and the power supply from possible damage
by overcurrent. The protection function operates when the load cur -
rent rises above an overcurrent set value (105% of the rated load
current). For a short-circuit or overcurrent lasting less than 20 se-
conds,
output voltage is decreased to protect equipment. When the
output current falls within the rated range, the overload protection
function
is automatically cleared.

operation
Note: Do not continue using the S8PS under short-circuited or
overcurrent conditions for longer than 20 seconds, other-
wise
the internal elements of the S8PS may be damaged or
broken.
600-W Models
If an excessive current flows for 5 s or more, the output will be turned
OFF and simultaneously protection-ON alarm indicator will be lit. T o
reset the S8PS, turn OFF the input voltage, leave the S8PS for at
least
three minutes, and then apply the input voltage again.
Note: Do not continue using the S8PS with the output terminals
short-circuited or the overcurrent condition continued,
otherwise
the internal elements of the S8PS may be dam -
aged
or broken.
Overvoltage Protection
The Power Supply is provided with an overvoltage protection func -
tion
that protects the load and the Power Supply from possible dam -
age
by overvoltage. When the output voltage rises above a set val -
ue
(1 15% of the rated output voltage), the protection function is trig -
gered,
shutting OFF the output voltage. If this occurs, reset the Pow -
er
Supply by turning it OFF for 1 minute min. and then turning it ON
again.

If the internal temperature of the S8PS rises excessively as a result
of fan failure or any other reason, the overheat protection circuit will
be triggered to protect the internal elements of the S8PS and simul -
taneously a protection-ON alarm indicator will be lit. To reset the
S8PS turn OFF the input voltage, leave the S8PS for at least one
minute
and then apply the input voltage again.

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 S8PS or heat radiation fin while the power is
being supplied or immediately after the power is turned OFF .
Otherwise,
a skin burn may result from the hot Switching Pow -
er
Supply or radiator .
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 .
When mounting the Power Supply, mounting it to a metal plate is
recommended.
Forced
air-cooling is highly recommended.
It is recommended that the clearance around the Power Supply be
larger than those shown on page 3 under Standard Installation.
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.

Parallel Operation
Only 300- and 600-W models can be in parallel operation provided
that they are operated under 90% of the ratings. Do not operate any
other models in parallel.
Make sure that the thickness and the length of all wires connected to
the load are the same to ensure that the wires will have no voltage
drop dif ferences.

Fan Replacement
The service life of the fan is approximately 50,000 hours (at 25 °C).
The
service life varies, however , depending on the ambient temper -
ature
or other surrounding environmental conditions such as dust.
As a preventive maintenance measure, replace the fan within two
years
if it is used at an ambient temperature of 40 °C.
Fans are available as replacements.
Model: S82Y -JFAN
