The FR-D720S-0.75K-CHT is a Mitsubishi Electric FR-D700 series inverter rated for 0.75 kW motor capacity. It accepts single-phase 200 to 240 V AC input at 50 or 60 Hz and delivers three-phase 200 to 240 V output to the motor. Rated output current is 4.2 A, with an overload capability of 150% for 60 seconds and 200% for 0.5 seconds (inverse-time characteristic) — enough to handle short-duration load spikes like startup or a jam without tripping. Protective structure is IP20 enclosed type. Self-cooled — no fan to fail or collect dust.
The FR-D720S-0.75K-CHT is a single-phase-input drive, so it's the right choice when you only have single-phase power at the panel — common in smaller shops or retrofit jobs. The FR-A740 series peers (like FR-A740-00015-NA) are three-phase-input drives with higher power ratings and a different frame size; they won't drop into the same panel footprint without rewiring and resizing the input protection. Stick with the FR-D720S if your line is single-phase 200-240 V and 0.75 kW.
