Mitsubishi Electric FR-A840-02600-2-60 Variable Frequency Drive

The Mitsubishi Electric FR-A840-02600-2-60 Variable Frequency Drive is a high-power VFD for industrial motor control, regulating speed, torque, and energy efficiency on large three-phase AC motors. Part of the FR-A800 series, it delivers 90 kW of rated power and accepts 380–480 VAC three-phase input with an output of 0–480 VAC and an adjustable output frequency from 0.2 to 590 Hz. It uses Advanced Vector Control or V/F Control for precise speed regulation under heavy loads, with 150% overload capacity for 60 seconds. For communication, it provides RS-485 (Modbus RTU) and optional network modules, and built-in PID control plus PLC functionality support complex automation tasks. Protection features include overcurrent, overvoltage, undervoltage, overload, and overheating, while cooling is forced air and mounting is panel mount, suited for installation in control panels. Typical applications include pumps, fans, compressors, and large conveyors in water treatment, HVAC, mining, and manufacturing lines, where high-capacity motor control and energy optimization are essential.
