Built on our all-compatible drive architecture, these liquid-cooled (LC) inverter modules are designed to fulfil all your requirements for motor control and for cabinet building. The ACS880 LC modules come in two frame sizes: R7i and R8i. The modules can be parallel connected for higher powers as they come with inbuilt du/dt output filters as standard.
The R7i modules come with an installation frame, which is fully generic and can be easily mounted into any kind of enclosure. The R7i is fully liquid-cooled with no airflow through the module, and can hence can be mounted in vertical or horizontal position and stacked on top of each other. This enables to build compact solutions for applications where e.g. the height of the enclosure is restricted. The R8i module with unique power density provides a perfect solution and optimized footprint for standard height cabinets.
The inverters use common DC bus systems to control several motors, but can also be used in a single drive configuration. The modules are DC supplied, with fuse protection, and have several built-in options. An optional DC-switch can be selected to disconnect an individual inverter unit from the DC bus. The AC output for the motor cabling is equipped with a quick connector, which enables easy installation and removal of the module from the cabinet. The R7i module has additionally quick connectors for the DC supply connection. Each inverter module comes with safe torque off (STO) as standard.
