Engineering Data

■ Derating Curve

■ 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.
