Mitsubishi Electric FREQROL-D700 FR-D740-0.75K is a compact micro inverter for controlling three‑phase induction motors at 380‑480 V AC, 3‑phase. Rated output 0.75 kW (1 HP). Built‑in RS‑485 communication (Modbus‑RTU, Mitsubishi inverter protocol), general‑purpose magnetic flux vector control for enhanced low‑speed torque (150% at 1 Hz), and STO safety function (SIL2/PLd). Self‑cooling, IP20 enclosure. Designed for general three‑phase motor speed regulation in industrial automation.

Applications:

  • Conveyor speed regulation and material handling

  • Fan and blower speed control in HVAC systems

  • Small pump speed control and fluid handling

  • Packaging machinery and food processing equipment

  • General OEM machine automation
