FR-D720S-0.75K-CHT FREQROL-D700 0.75kW Single-Phase Inverter | Mitsubishi

The Original New Mitsubishi FR-D720S-0.75K-CHT is a 0.75 kW single‑phase 200 V class inverter from the FREQROL-D700 series, designed for compact and reliable variable speed control of three‑phase induction motors. It accepts a single‑phase 200–240 V AC supply and delivers a three‑phase output with a rated current of 4.2 A. Featuring general‑purpose magnetic flux vector control, the drive achieves 150% starting torque at 1 Hz for demanding low‑speed applications. Built‑in RS‑485 Modbus‑RTU communication, integrated brake transistor, and configurable protective functions make it a versatile solution for machine automation, pumps, fans, and conveying systems.
