The Mitsubishi FR-D740-022-CC is a compact motor drive from the FR-D700 series, rated for 2.2 A output current at 1 HP on a 400 V three-phase supply. Its distinguishing feature is the conformal coating on the PCB — a factory-applied protective layer that resists moisture, dust, and mild corrosive atmospheres. That makes this variant a better fit for environments where condensation or airborne contaminants are a concern, like pump houses or washdown zones, compared to a standard uncoated drive.
The 2.2 A rating is the continuous output current at the rated switching frequency — enough to drive a 1 HP (0.75 kW) four-pole induction motor on a 400 V line. The three-phase input is fixed; this unit will not run on single-phase supply without derating or an external phase converter. The conformal coating adds no electrical performance difference, but it does change the part's suitability for certain installation classes — if your site spec calls for coated electronics (common in food processing or outdoor cabinets), this is the correct FR-D700 variant to order.
