Specified Area
Specified area:
At an output current from 0A to I
2 Nominal
the unit fulfills all specified data.
Overload area:
At an output current from I
2 Nominal
to I
2 Overload
the power supply delivers the
specified output voltage U2.
The unit is not long time overload proof. If the unit is powered longer than 1 min
in overload conditions, the device can be damaged. The period between two
overload conditions has to be at least 15 minutes.
Fold back area:
If the power demand would be greater than I
2 Overload
or the power supply
works in short circuit the output voltage and current can not be defined (this
parameters are not stable). The wattage of the SMPS is de-rated. In this mode
the unit can not be damaged. After removing this conditions the unit fulfills the
specification.
