April 2, 2019 - Mitsubishi Electric has extended its inverter portfolio with a 690V version of its FR-A800 series inverters. The new models of the FR-A870 690V line cover power outputs up to 1.5 MW. The FR-A870 line combines this performance with features which enhance functionality, including a built-in brake chopper on all power sizes up to 200 kW to shorten deceleration times.
The inclusion of a built-in brake chopper offers advantages in higher-powered machinery applications that are characterized by rapid acceleration and deceleration rates. It shortens deceleration time, eliminating the need for an external brake unit or regeneration converter. Further, by eliminating the need for an external brake, machine builders can pass on a cost reduction in any servicing and maintenance that would previously have been required on the mechanical component.
Additional features include a DC reactor and EMC filter which remove the need for external ancillary components and combine with the design of the FR-A870 itself to save space and reduce wiring requirements. The FR-A870 models also comprise other standard features, including integrated PLC, a USB port for programming and parameter copying, a control panel, functions for system safety, three expansion slots and a choice of network card.
The first FR-A870 inverter is initially available to cover powers from 160-200 kW, with further models in the pipeline to extend the coverage from 37 kW – 1.5 MW, forming a comprehensive range of inverters for high power applications.
