I 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 current
rises above an overcurrent set value (105% of the rated load cur-
rent). For a short-circuit or overcurrent lasting less than 20 seconds,
output voltage is decreased to protect equipment. When the output
current falls within the rated range, the overload protection function is
automatically cleared.
I Overvoltage Protection
The Power Supply is provided with an overvoltage protection function
that protects the load and the Power Supply from possible damage
by overvoltage. When the output voltage rises above a set value
(115% of the rated output voltage), the protection function is trig-
gered, shutting OFF the output voltage. If this occurs, reset the
Power Supply by turning it OFF for 1 minute min. and then turning it
ON again.

Note: Do not continue using the S8PS under short-circuited or over-
current conditions for longer than 20 seconds, otherwise the in-
ternal 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. To
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, other-
wise the internal elements of the S8PS may be damaged or
broken.
300- and 600-W Models Only
The overvoltage protection-ON alarm indicator lights when the func-
tion is operating.
I Overheat Protection Function
600-W Model Only
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.
