Mitsubishi FR-A840-00310-2-60 Variable Frequency Drive for FREQROL FR-A800 Series

The Mitsubishi FR-A840-00310-2-60 (FR-A840-00310-2-60) is an industrial variable frequency drive inverter engineered for the FREQROL FR-A800 Plus series. Designed to deliver precise speed and torque regulation for three-phase induction and permanent magnet motors, this high-performance inverter operates with an input voltage range of 380 to 500 V AC across 400 V, 415 V, and 480 V nominal three-phase power systems. It provides an output frequency range of 0.2 to 590 Hz, accommodating demanding motion and high-speed industrial processing requirements. Equipped with an integrated CA current terminal supporting 0 to 20 mA signals and built-in Modbus RTU serial communication, the FR-A840-00310-2-60 integrates smoothly into plant automation and supervisory control networks. The drive features an IP20 degree of protection and incorporates conformally coated printed circuit boards compliant with IEC 60721-3-3 classes 3S2 and 3C2 for superior resistance against chemical contamination and harsh operating environments. It serves as a direct functional equivalent to FRA84000052260 in automated production machinery, pumping systems, and process lines.
