■ Overload Protection
50- to 300-W Models
The Power Supply is provided with an overload protection function
that protects the power supply from possible damage from an
overload. The protection function operates when the load current
rises above an overcurrent detection value (105% of the rated load
current except for 300-W models, for which the value is 101%). For a
short-circuit or overload 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.

600-W Model
If the overload state continues for 5 seconds or longer, the output will
shut off and the protection-ON alarm indicator will simultaneously
light. Reset the input power by turning it OFF for at least one minute
and then turning it back again.

■ Overvoltage Protection
The Power Supply is provided with an overvoltage protection function
that protects 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 triggered,
shutting OFF the output voltage. Reset the input power by turning it
OFF for at least one minute and then turning it back again.
The valves shown in the above diagram are for reference only.
300- and 600-W Models
If more than approx. 115% of the rated output voltage is output, the
output will be shut off and simultaneously the protection-ON alarm
indicator will light. Reset the input power by turning it OFF for at least
one minute and then turning it back again.
■ 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 parts of the S8PS and
simultaneously a protection-ON alarm indicator will be lit. Reset the
input power by turning it OFF for at least one minute and then turning
it back again.
