An overview of the advantages of using our frequency inverters in industry:

Open and flexible drive platform

The frequency inverters are designed for seamless integration into existing automation and drive systems and support a wide range of common fieldbus and industrial Ethernet networks. Depending on the model, many communication interfaces are already integrated or can be flexibly expanded.

High reliability in continuous industrial operation

Robust power electronics, integrated protection and overload functions, temperature-resistant capacitors and permanently lubricated cooling fans ensure safe and trouble-free operation – even under continuous load and fluctuating mains voltage.

Optimised control and data management

Modern communication interfaces enable transparent monitoring of operating data and precise speed and process control. This allows frequency inverters to be efficiently integrated into digital control and management systems.

International standards & certified safety

Our frequency inverters comply with all relevant international standards and directives, including the EU Low Voltage Directive (2014/35/EU), the EMC Directive (2014/30/EU) and the Machinery Directive (2006/42/EC). In addition, they have CE marking and international certifications such as UL, cUL, EAC, CCC and various marine certificates.

Our product series: The right frequency inverter from Mitsubishi Electric for every application

Mitsubishi Electric frequency inverters cover a wide range of power and voltage ratings – from compact inverters in the kilowatt range to powerful industrial drive technology from 11 kW and above.

Available as 230 V (single-phase) and 400 V (three-phase) frequency inverters, they are suitable for a wide variety of motors and applications – from pumps and fans to powerful three-phase motors in industrial plants.

This means that the right frequency inverter is available for almost every application.

FR-A Series – High-performance frequency inverters for demanding applications

The FR-A800 series frequency inverters offer precise torque and speed control, high overload capacity and advanced energy-saving functions. They are ideal for demanding industrial applications such as cranes, winders and conveyors, as well as for heavy-duty tasks such as lifting or crushing. Mains voltage: 200–690 V, three-phase (50/60 Hz) Power range: 0.4–630 kW (parallel operation up to approx. 1,500 kW)

FR-F Serie – Frequenzumrichter für Pumpen & Lüfter

The frequency inverters of the FR-F800 series are specially designed for pump and fan applications and enable particularly efficient operation thanks to integrated energy-saving functions. They support permanent magnet and SynRM motors and increase system availability through predictive maintenance. Mains voltage: 230 V / 400 V, three-phase (50/60 Hz) Power range: 0.75–630 kW

FR-E Series – Frequency inverters for demanding applications in the lower power range

The FR-E800 frequency inverters offer sensorless vector control, integrated PLC and safety functions for the lower and medium power range. Thanks to broad communication support and optional IP67 design, they can be flexibly integrated into existing systems – even in harsh industrial environments. Mains voltage: 100–230 V single-phase · 230–600 V three-phase Power range: 0.1–2.2 kW (1-ph) · 0.1–22 kW (3-ph)

FR-D Series – Efficient miniature frequency inverter for small drives

FR-D frequency inverters are designed for simple applications and impress with their compact design, easy commissioning and reliable operation. Functions such as vector control, service life diagnosis and the control of permanent magnet motors make them a robust solution for more demanding basic applications. Mains voltage: 230 V single-phase · 400 V three-phase (50/60 Hz) Power range: 0.1–2.2 kW (1-ph) · 0.4–7.5 kW (3-ph)

FR-CS80 Series – The compact and cost-effective frequency inverter for standard applications

The FR-CS80 is a compact and economical solution for simple standard applications. With general-purpose magnetic flux vector control, it offers solid control quality in the lower power range and is ideal for space-saving installations with an attractive price-performance ratio. Mains voltage: 230 V single-phase · 400 V three-phase (50/60 Hz) Power range: 0.4–2.2 kW (1-ph) · 0.4–15 kW (3-ph)

Medium-voltage frequency inverter

Mitsubishi Electric's medium-voltage frequency inverters are designed for particularly powerful applications such as large machines, pumps and energy-intensive industrial processes. They enable high efficiency and reliable operation from several hundred kilowatts up to the megawatt range – e.g. in shredders in metal recycling. Mains voltage: 3,000–11,000 V, three-phase Power range: 160–3,860 kW
