Mitsubishi FR-A840-00770-E2-60 Variable Frequency Drive for FREQROL FR-A800 Plus Series

The Mitsubishi FR-A840-00770-E2-60 is an advanced variable frequency drive engineered for high-performance motor control within the FREQROL FR-A800 Plus series. Designed for demanding industrial automation setups, this three-phase variable speed drive regulates AC motor operation by converting electrical power across an input voltage range of 380 V AC to 500 V AC at 400 V AC, 415 V AC, or 480 V AC nominal ratings. It delivers an adjustable output frequency spanning from 0.2 Hz to 590 Hz, ensuring smooth acceleration, precise torque regulation, and optimal motor efficiency. Equipped with integrated Modbus RTU communication capabilities, the drive facilitates seamless networking and real-time monitoring across supervisory control systems. The unit includes a CA terminal supporting 0 to 20 mA analog signals and features conformal coating on the printed circuit board assembly. This coating complies with IEC 60721-3-3 classes 3C2 and 3S2 for chemical and environmental resistance, shielding internal electronics against harsh industrial atmospheres. With an IP20 ingress protection rating, the drive provides reliable operation in enclosed control cabinets. The unit is functionally equivalent to part number FRA84000052260, serving as a direct replacement in factory automation and machinery drive systems.
