ACS880-107LC - liquid-cooled inverter units

Compact design with high power density

Built on our all-compatible drive architecture these liquid-cooled inverter units are DC supplied and have built-in capacitors for smoothing the DC voltage. The electrical connection to the common DC bus is fuse protected. An optional DC-switch can be selected to disconnect an individual inverter unit from the DC bus.

The ACS880 inverter units come in two frame sizes: R7i and R8i. The R8i unit can be parallel connected for building high power inverters in multidrives. The R8i has speed-controlled cooling fans, quick connectors for motor cabling and wheels for easy installation and transport. The R7i unit also has quick connectors for DC bus.

The design is extremely compact which enables optimized drive cabinet installations. One drive unit can deliver motor current up to 850 A.
