Mitsubishi FR-D720S-042SC-EC: FR-D700 variable frequency drive, 0.75 kW, 4.2 A output at normal duty, 1x 200-240 V.
Before replacing a failed drive, check the motor and cable insulation and the braking resistor: a short on the output side can damage a new inverter in the same way.
Mitsubishi Electric lists the FR-D720S-042SC-EC as discontinued (EOL 01.01.2026, last time buy 31.12.2026). Spares for installed machines remain in demand; ask us for stock or for the current successor before you plan a retrofit.
