Figure 29 – Derating curve compared to input voltage - use of only channel IN1
NOTE: The curves show a zone of non operation up to 90V; a linear
derating zone up to 170V (PVI-4.6-I-OUTD), and 140V (PVI-3.8-I-OUTD);
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 switched on
it will continue to operate 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.
