Mitsubishi Electric FR-A840-00620-2-60 Variable Frequency Drive

The Mitsubishi Electric FR-A840-00620-2-60 is a 30 kW variable frequency drive (VFD) from the FR-A800 series designed to regulate speed and torque of three-phase AC motors while boosting energy efficiency in industrial automation. It accepts 380–480 VAC input (three-phase) and delivers an output range of 0–480 VAC with an adjustable output frequency from 0.2 to 590 Hz, enabling precise motor control for pumps, fans, compressors, and conveyors. Control is available via Advanced Vector Control or V/F Control, with a 150% overload capacity for 60 seconds to handle startup and transient loads. For integration and remote monitoring, the drive provides RS-485 (Modbus RTU) communication, with the option to add network modules. Built-in functions include PID control and PLC functionality, supporting closed-loop control and simple logic without extra hardware. Protection covers overcurrent, overvoltage, undervoltage, overload, and overheating, while forced-air cooling supports reliable operation in demanding environments. Panel-mount installation facilitates straightforward integration into control panels and industrial racks. Typical applications include HVAC systems, water treatment facilities, material handling lines, and manufacturing processes where stable speed control, energy savings, and smooth motor performance are essential.
