The Mitsubishi Electric FR-E740-2.2K-CHT AC Inverter Drive is a 2.2 kW (3 HP) variable frequency drive (VFD) in the FR-E700 Series designed for precise speed and torque regulation of three-phase motors in industrial control systems. Its unfiltered design (CHT variant) makes it suitable for installations requiring external EMI filtering or customized setups. Commonly used in conveyors, pumps, fans, and compact machinery, it supports energy savings and repeatable speeds in light to medium-duty automation environments. Key specifications include an input of 380–480V AC, 3-phase; output current approximately 5.5 A; control methods such as V/F control and advanced vector control; a frequency range from 0.2 to 400 Hz; overload capacity rated at 150% for 60 seconds; forced-air cooling; IP20 protection; RS485 communication with Modbus RTU support; and panel-mount installation. Common replacements include Mitsubishi FR-E740-2.2K, Mitsubishi FR-D740-2.2K, and Schneider ATV320U22N4B.
