Extended operating area (L type only)
Of the output current setting range of the PWR as illustrated in
figure below, the range between the rated output current and the
maximum output current (160 % of the rating) is the extended oper-
ating area. The specifications of load fluctuation, input fluctuation,
ripple/noise, and so on are not met in the extended operating area.
The extended operating area is divided into the continuous extend-
ed operating area and the intermittent extended operating area.

Continuous extended operating area
• Extended operating area
Continuous output is possible. At ambient temperatures greater
than or equal to 30 ºC, the output current must be derated with
respect to the temperature.
• Continuous extended operating area
The output duration is limited.
Guideline of the time duration of operation (When operating by
itself with no devices that generate heat around the PWR.)
Maximum Output Duration: 10 minutes
Pause Duration: At least twice the output duration
When using the PWR in the extended operating area, pay attention
to the ambient temperature, preset current, and output duration.
