Mitsubishi Electric FR-A740-1.5K-CHT Frequency Inverter

The Mitsubishi Electric FR-A740-1.5K-CHT Frequency Inverter is a 1.5 kW (2 HP) industrial variable frequency drive (VFD) from the FR-A700 series that provides precise speed and torque control for three-phase AC motors. It uses advanced vector control (V/F and sensorless vector) with 3-phase input 380–480 VAC and 3-phase output across a range, delivering about 4.1–4.5 A and an overload capacity of 150% for 60 seconds, and it suits conveyors, pumps, fans, compressors, machine tools, and production equipment. Features include built-in braking transistor (model dependent), RS-485 (Modbus RTU compatible) communication, and protection functions for overcurrent, overvoltage, undervoltage, overload, and overheating, with forced-air cooling and IP20 protection in a panel-mount housing operating from -10°C to 50°C. This model is discontinued and replaced by the FR-A800 series, with common replacements including FR-A840-1.5K-CHT, FR-A820-1.5K, and FR-E740-1.5K.
