Low voltage AC drives

ABB industrial drive

ACS880 – Multidrive

A multidrive is a custom-made system to suit a larger application
or a process line. The system contains multiple inverter stages of
differing size, supplied from a common DC bus. Rectifier Inverter

ABB can provide a ready-made cabinet, or it can provide system
integrators with a comprehensive range of power modules and
Inverter
4 mechanical kits to build bespoke cabinets for end clients.

Multidrive cabinets
– 1.5 kW to 5600 kW Inverter
– IP21 as standard IP42 as option
– High packing density with 16 inverter units (up to frame size
R2i) can be installed into one 1000 mm cabinet
– Diode bridge that is highly reliable with high power density
– Fast connectors for motor cables in the bottom part of the
cabinet, making installation easy
– Integrated safety including safe torque-off (STO) as
standard with several safety functions as options
– Coated boards as standard
– Braking options
– DC fuse disconnectors, DC fuses or DC fuse switch
including charging circuit for inverters
– Cabinet light and heater options
– Highly efficient thermal handling as heat loss of each
inverter unit is guided to the back of the cabinet. All
cabinets are their own separate compartment
– Long lifetime capacitors and high efficiency cooling fan with
speed or on-off control
– TÜV approved emergency stops
– ACS880 user interfaces described later
For further information, see Technical Catalogue 3AUA0000115037
Multidrive modules
– 1.5 kW to 3200 kW
– A range of IP20 modules and IP00 kits to generate bespoke
multidrive systems built-into system integrators own panels
– Modules have no rectifiers, they are inverters only and range
in frames from R2i to R8i (i=inverter only)
– Contain internal pre-charge circuits making them easier
to integrate
– Selection of rectifiers available to generate DC link for the
system. Active IGBT rectifiers and diode modules
are available
– New style diode module (DxD) only contains diodes, making
it more competitively priced and more reliable
– New RRU modules, regenerative rectifiers, cost efficient For further information, see Technical Catalogue 3AUA0000115038
regeneration
– Cabinet kits ensure easy integration – Safe torque-off (STO) as standard with several safety
– New redundancy configurations for the modules and the fan functions as options using the new safety module
control for better problem ridethrough – Coated boards as standard
