Mitsubishi FR-A840-0.75K-1 0.75kW Variable Frequency Drive FREQROL FR-A800

The Mitsubishi FR-A840-0.75K-1 (FR-A840-0.75K-1) is a high-performance variable frequency drive designed for industrial motor speed and torque regulation within the FREQROL FR-A800 and FR-A800 Plus series. Engineered for three-phase AC input voltages ranging from 380 V to 500 V at 50/60 Hz, including nominal 400 V, 415 V, and 480 V networks, this inverter delivers reliable operation across demanding manufacturing environments. It features a rated output capacity of 0.75 kW (1 HP) with an output current rating of 2.5 A under normal duty conditions and supports an adjustable output frequency from 0.2 Hz up to 590 Hz. Equipped with integrated Modbus RTU communication capabilities, an analog CA terminal (0-20 mA), and an IP20 ingress protection rating, the unit ensures seamless automation integration and panel mounting. The internal printed circuit boards feature a protective conformal coating rated to IEC 60721-3-3 classes 3C2 and 3S2, providing superior chemical and environmental resistance against airborne contaminants. This inverter is widely used in automated machinery, conveyors, pumps, and process drive systems requiring dependable three-phase motor control.
