Connection to mains Unlimited (internal overload protections)
Current THD Depends on additional chokes (normal case < 40%)
Starting delay Depend on DC bus capacitance (max. 10 s)
Unexpected input power
break
Shorter breaks than 40 ms work normally if DC does
not drop remarkably. A longer break means normal
starting operation (charging current varies according
to load).
DC connection
Output voltage U
out
465-800 V DC (380-500 V AC)
640-1100 V DC (525-690 V AC)
Efficiency >98%
DC bank capacitance 6.8 µF (includes 10 MΩ discharging resistor)
Control
characteristics
Control method
NFE is an independent power unit. Charging and pro-
tections are controlled by the NFE itself.
