Maximum power supply drop out time (Buffer time/voltage failure buffer) of AVy is achieved by adding the
maximum recommended capacitance to the DC bus.
The following table show the maximum power supply drop out time for different Undervoltage thresholds
and inverter sizes. The meaning of the symbols in the colums is as follows:
C
std
= internal capacitance (in uF),
C
ext
max = max external total capacitance (in uF),
T
buff
= max drop out time (in sec.),
P
SMPS
= power supply (watts),
U
buff
= volts threshold to disable drive operation (in volt),
U
min
= min DC volts that will support the power supply (in volt)
Where T
