(PVI-10.0/12.0-I-OUTD(-S)-400 Rev:1.3)
NOTE: The curves show a zone of non operation up to 90V; a linear
derating zone up to 220V (PVI-10.0-I), and 250V (PVI-12.0-I); a zone of
constant rated power; and a high-voltage derating starting at 470V.
Actually, the low-voltage operating zone depends on the setting of the
minimum starting voltage (200V default). Once the converter is started
up, it will continue to work according to the curves up to a minimum
value of 70% of the set starting voltage (i.e. with a default value of 200V,
the converter will have a minimum operating voltage of 140V).
Conditions for power reduction due to environmental conditions and input voltage
may occur at the same time, but power reduction will always occur with reference
to the lower detected value.
