Low voltage (LV)
The Low voltage option allows to run the unit at low
voltage (= high current).
! All the cables that are used must be
suitable for high current.
Q1 ....... Circuit breaker for low voltage, high
current
Interrupts the low voltage power supply
towards X1 when a short-circuit occurs at
the load side or when the overcurrent
protection (QAS 60: 175 A, QAS 80: 237 A,
QAS 100: 280 A) is activated. It must be
reset manually
problem.
Dual voltage (2V)
The dual voltage option is only
!
available
Qc1002™ controller.
1 phase - 3 phase
Q1
The generator can run in two different modes:
1 phase, lower voltage
When using this selection, the generator provides a
230 V output voltage.
3 phase, higher voltage
When using this selection, the generator provides a
400 V output voltage.

3 phase - 3 phase
3 phase, lower voltage
When using this selection, the generator provides a
230 V output voltage. (IT = active)
3 phase, higher voltage
When using this selection, the generator provides a
400 V output voltage. (ELR = active)
