2.
Output characteristics are measured at the power supply output terminals.
3.
If the output voltage adjuster (V.ADJ) is turned, the voltage will increase by more than 50% of the voltage adjustment range. When
adjusting the output voltage, confirm the actual output voltage from the Power Supply and be sure that the load is not damaged.
4.
The settings for the output voltage must be within the following range:
+V:
±1%
of the rated value
–V:
±5%
of the rated value

Overload Protection
The power supply is provided with an overload protection function
that protects the Power Supply from possible damage by overcurrent.
When the output current rises to 105% or higher of the rated current,
the protection function is triggered, automatically decreasing the
output voltage. When the output current falls within the rated range,
the overload protection function is automatically cleared.

The values shown in the above diagram are for reference only.
Note:
Internal parts may occasionally deteriorate or be damaged if a
short-circuit or other overcurrent state continues during
operation. Eliminate the overcurrent state as soon as possible.
Dual Output Models
The total output power for the +V output and
−V
output is detected for
the protection operation (i.e., total overcurrent protection), but this
condition varies depending on –V output status. –V output has an
independent short-circuit protection feature.
