Product Description

The Mitsubishi FR-A840-00023-2-60 is a compact and versatile variable frequency drive (VFD) from the A800 series, designed to control the speed and torque of three-phase induction and permanent magnet motors. It operates on a 380–500V AC supply and delivers a rated output of 0.4 kW (1.5 A), making it suitable for applications requiring constant torque, such as conveyors and pumps. The inverter features vector control, V/f control, and sensorless vector control methods, providing precise motor control. It includes integrated digital and analog inputs and outputs, relay contacts, and supports communication via RS-485 (Modbus RTU). The unit is housed in a compact IP20-rated enclosure, with dimensions of 150 mm (W) x 260 mm (H) x 140 mm (D) and weighs approximately 2.8 kg. Conformal coating and EMC filtering are standard, ensuring reliable operation in industrial environments.​
