Its 2.2 A rated output and 1.7 kVA capacity match the full-load current of a standard 0.75 kW motor at 400 V, so the drive runs at nameplate without derating. The 150% overload for 60 seconds (200% for 0.5 s) handles short-duration high-torque events like starting a loaded conveyor or breaking away a sticky pump — the inverse-time characteristic means it lets the motor pull hard briefly but trips fast on a sustained stall. Input tolerance is wide: three-phase 380-480 V at 50/60 Hz, with permissible fluctuation from 325 to 528 V. That covers nominal 400 V and 480 V grids globally, plus saggy sites where line voltage drops under heavy load. The 2.5 kVA power supply capacity gives headroom for the DC bus charging circuit and internal losses. ## What the overload rating buys you The 150% overload for 60 seconds is the figure that governs real-world motor starting and intermittent overloads. For a 0.75 kW pump or fan, that means the drive can deliver 3.3 A (150% of 2.2 A) for a full minute to accelerate the load — enough for most direct-on-line starts. The 200% for 0.5 s covers the magnetizing inrush when the motor first picks up. The regenerative braking torque of 100% means the drive can absorb full rated torque during deceleration without an external braking resistor, as long as the duty cycle is moderate.","metaTitle":"Mitsubishi FR-D740-0.75K-CHT D700 Inverter, 0.75 kW, 2.2 A","metaDescription":"Mitsubishi FR-D740-0.75K-CHT D700 series inverter, 0.75 kW, 2.2 A output, 150% overload for 60s.
