Overload Protection
The Power Supply is automatically protected from short-circuit or
overcurrent damage by the overload protection function. Overload
protection is activated if the output current rises above 105% of the
rated current.

When the output current returns within the rated range, overload pro-
tection is automatically cleared.

Outputs are interrupted if an overload continues for 5 seconds or
more. To reset the Power Supply, leave input power OFF for more
than 3 minutes and then turn it ON again. Alternatively, turn OFF and
ON the remote control signal.
The values shown in the above diagrams are for reference only.
Note: 1. If the Power Supply has been short-circuited or supplied
with an overcurrent longer than 30 seconds, the internal
parts of the Power Supply may occasionally be deteriorated
or damaged.
2. The internal parts may possibly be deteriorated or dam-
aged. Do not use the Power Supply for applications where
the load causes frequent inrush current and overload.

MTBF stands for Mean Time Between Failures, which
is calculated according to the probability of accidental
device failures, and indicates the reliability of a device.
Therefore, it does not necessarily represent the life of
the Power Supply.
Life
expectancy
10 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.
