3.2 Non-regenerative power supplies
The non-regenerative QC-PS-
power supplies are part
of the FAGOR QuerCus-Power Drive System. They are
connected via the mains filter to the three-phase mains
with line voltages between 400 (1-10%) V AC and 480
(1+10%) V AC and line frequencies of between 50 (1-
4%) Hz and 60 (1+3.3%) Hz.
The QC-PS-025 power supply comes integrated with an
auxiliary power supply allowing for the system control
electronics to be supplied with +24 V DC.
The QC-PS-045 power supply does not come with any
auxiliary power supply and, therefore, it must ALWAYS
be installed with the QC-APS-15 external auxiliary power
supply to feed the system control electronics with +24 V
DC.

WARNING.
The DC BUS discharge period may extend for up to
10 min after the equipment has been disconnected from the elec-
trical mains. For this reason, always
ensure that there is no volt-
age in the DC BUS before handling the equipment.
