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), the protection function is trig-
gered,
decreasing the output voltage. When the output current falls
within the rated range, the overload protection function is automati -
cally
cleared.

Dual Output Models
+V output is provided with an overload protection that protects the
load and the power supply by detecting total load value of +V and –V
output. It operates at 105% min. of the rated current of +V output
when
–V output is producing the rated output, but this condition va -
ries
depending on –V output status. –V output has an independent
short-circuit protection feature.
