Frequency Inverters FR Family

Frequency inverter drives are a key component of Mitsubishi Electric's factory automation systems. More than 30 years on and with over 14 million units sold worldwide, Mitsubishi Electric is still continually contributing innovations to variable-speed drive technology. The latest 64-bit RISC processors, advanced software models and the latest power electronics make today's variable-speed drive solutions from Mitsubishi Electric both powerful and easy to use. Mitsubishi Electric delivers innovative, open, flexible and reliable drive solutions geared to the special needs of individual markets and customers.

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.

 

The FR-A741’s regenerative braking system makes it much more efficient than conventional drive systems, giving it the potential for significant energy savings. They are particularly well suited for tasks involving frequent cyclical acceleration and deceleration and in all applications where braking resistors are normally used. The combination of the integrated AC reactor and no need for an external braking unit eliminate a large amount of additional wiring. These inverters need up to 60 % less main circuit wiring and occupy up to 40 % less space than conventional solutions, depending on the output capacity.

The FR-F740 frequency inverter drives from Mitsubishi Electric are designed for the special needs of pumps and fans. These inverters can significantly enhance the energy balance of pump and fan applications - particularly in the low-speed range and in low-load operation, where energy savings of up to 60% can be achieved. Additional savings are made possible by Mitsubishi Electric's innovative OEC (Optimum Excitation Control) technology. This system ensures that the optimum magnetic flux is always applied to the motor, thus reducing losses. The result is maximum utilisation of motor capacity at maximum efficiency.
