Frequency inverter
For new services
Mitsubishi Electric is rounding off its frequency inverter portfolio and supplying devices for additional voltage and power ranges. Among other things, the supplier has strengthened its offering in the large capacity inverter (LCI) range from 75 kilowatts, particularly with the 800 series for low voltage.
hile the flagship FR-A800 with four load characteristics is generally designed for heavy-duty operation, the FR-F800 is aimed specifically at applications for fans and pumps. With regard to industrial networking, Mitsubishi Electric is equipping all new devices with an Ethernet on-board card. A new addition to the 800 series is the type series for industrial three-phase mains voltage 690 volts in addition to 400 and 200 volts. At higher voltages, the devices can operate with lower currents, which reduces the cable cross-sections. All large frequency inverters from Mitsubishi Electric - 75 to 630 kilowatts - have a compact design, which means they are ready for connection for simple control cabinet installation and standardized commissioning. The FR-A800-LC series with liquid cooling (Liquid Cooled) is currently available in sizes from 110 to 355 kilowatts; these inverters are suitable for tunneling and mining or heavy industry. The FR-A800 Plus series is equipped with firmware and pre-configured functions for special applications, such as crane applications and winding applications. pb
