8.2 Power Settings
The power limit settings (parameter
OP.Hi
) for the VCF models on various supply voltages are as
follows. The figures represent the maximum percentage of time that controlled power is supplied
to the elements. Do not attempt to “improve performance” by setting a value higher than the
correct one from the table.
