Mitsubishi Inverters



Mitsubishi frequency inverters satisfy all the standards and specifications of the European Union's 2006/95/EC directive on low-voltage equipment and the 2006/42/EG machinery directive. All products have a CE certificate subject to 89/336/EEC, and also UL, cUL and DNV certificates and the certification for the Russian market. All important protective functions are included as standard equipment, and all Mitsubishi frequency inverters conform to both the ISO 9001 quality standard and the ISO 14001 environment standard.

Distribution network for Motor & Variable Speed Drives packages.Brook Crompton Electric Motors and Mitsubishi Electric inverters are widely recognised as “best-in-class” and, when matched together, create a world-class variable-speed drive system which is efficient, reliable and user friendly.


Energy saving and regenerating frequency inverters



Mitsubishi inverters are real energy savers achieving maximum drive capacity utilisation with minimum power consumption. Flux optimisation ensures that the connected motor only gets exactly the amount of magnetic flux required for optimum efficiency. This is particularly important at low speeds as motors are normally using a voltage/frequency control system. SLV Vector Control with Online Auto tuning and automatic slip compensation, V/f control with a fully-programmable characteristic and Mitsubishi Electric's advanced OEC (Optimium Excitation Control) technology all help to make these frequency inverters masters of energy conservation. They can achieve maximum power savings of up to 60% compared to conventional mains operation, thus minimising system operating costs.


Product range



The series covers a very broad output range from 0.1kW all the way up to 630kW. Lines include the smallest FR-D700 series for simple applications, the medium-range FR-E700 series and the high-performance FR-A700 series. The product range is complemented by the FR-F740 series that is optimised for the special requirements of pump and fan applications in the HVAC sector.
All frequency inverters feature simple operation and configuration and optimised control and data management facilities. The integrated control terminals, the one-touch digital dial and the multi-language control panel with copy function provide instantly-comprehensible information on current drive status and clear error message displays.
