Auxiliary Power Supply; Standard Configuration; Alternative Configurations; Cabinet Layouts - ABB ACS580MV Hardware Manual

The secondary side of the input transformer is a multi-winding configuration that matches
the number of individual power modules (3 x 5 modules (6/6.3 kV) or 3 x 6 modules (6.6
kV) or 3 x 8 modules (10 kV) or 3 x 9 modules (10.5/11 kV).

Auxiliary power supply


The drive needs auxiliary power for:
•
the cooling fans
The power is always fed by a three-phase power supply.
•
the control hardware
The power is fed by a single-phase power supply.
•
the optional cabinet heaters
The power is fed by a single-phase power supply.
The power feed for the auxiliary supply must be protected with a suitable circuit protection
rated for the inrush current. For information on the type dependent auxiliary power
consumption figures, see ACS580MV power supply consumption of the drive in the
ACS580MV Engineering
Several auxiliary power supply schemes are available. As a standard, the customer has to
provide the following supplies:

Standard configuration

•
External 3 phase supply for fan supply (380 - 425 VAC)
•
External single phase supply for control supply (100 - 240 VAC or 120 - 370 VDC)
•
With optional cabinet heaters: additional external single phase supply (220 - 240 VAC)
Alternatively:
•
External 3 phase supply with PE and neutral line (380 - 425 VAC)
Control auxiliary power is taken from one phase and the neutral line.
•
With optional cabinet heaters: additional external single phase supply (220 - 240 VAC)
