If you're shopping for VFDs, soft starters, and motor controls, the decision usually comes down to two questions: what input power do you have, and what size motor are you feeding? The four drives here answer those questions in different ways, from a small single-phase-input 1HP unit to 10HP drives that can accept single or three-phase input.
Quick take
For a single-to-three-phase conversion at 1HP, the Single To 3 Phase 750W 1HP 220V unit is the least expensive entry point. If you already have 240VAC three-phase power and need a 2HP drive, the Mitsubishi FR-D720-070-W1 is the three-phase-input option. For larger motor work, both 1 To 3 Phase drives accept 1 or 3 phase input, with the main trade-off between their listed prices and output frequency specs.
Listed price comparison
| Product | Listed price | Price bar |
|---|---|---|
| Mitsubishi FR-D720-070-W1 240VAC 3 Phase VFD 2.0HP | USD 129.99 | |
| Single To 3 Phase 750W 1HP 220V VFD | USD 32.99 | |
| 1 To 3 Phase 7.5KW 10HP 220V VFD | USD 130.11 | |
| CNC 1 To 3 Phase 220V VFD 7.5KW 10HP | USD 118.92 |
Decision matrix
- 240VAC three-phase input and a 2HP rated load: the Mitsubishi FR-D720-070-W1 fits.
- Small 1HP three-phase motor with only single-phase 220V in the workshop: the 750W Single To 3 Phase drive is the match.
- 10HP motor with either single or three-phase 220V input and a wide output frequency spec: the 1 To 3 Phase 7.5KW drive is worth considering.
- Same 10HP class with a lower listed price and multiplex terminal functions: the CNC 1 To 3 Phase 7.5KW drive is the alternative.
Product notes
Mitsubishi FR-D720-070-W1 240VAC 3 Phase Variable Frequency Drive 2.0HP
This drive answers the three-phase-input case. It is listed at USD 129.99 and carries the model number FR-D720-070-W1, with a power rating of 1.5kW and a rated load of 2HP. The input voltage is 240VAC and the number of phases is three, so it expects an existing three-phase supply. The condition is listed as new, and the MPN matches the model. Choose it when you already have three-phase power and want a Mitsubishi Electric unit for a 2HP motor. Its limitation is the input requirement: it expects 240VAC three-phase on both input and output, so it will not help if your shop only has single-phase power.
Single To 3 Phase 750W 1HP 220V Variable Frequency Drive Inverter VFD/VSD
At USD 32.99, this 0.75kW drive is the least expensive entry point in this lineup. It takes single-phase AC 220V input and converts it to three-phase AC 220V output, making it a lower-priced phase converter for a small three-phase motor. The model is FOR T13-750W-H, and the power rating is 0.75kW. Rated current is 3.41A while maximum input current is 3.86A. Choose it for very small 220V three-phase motors. Its limitation is its size: at 1HP/0.75kW, it is suited only to modest machinery, not high-torque or larger motors.
1 To 3 Phase 7.5KW 10HP 220V Variable Frequency Drive Inverter CNC VFD VSD
This drive is listed at USD 130.11 and brings 7.5kW/10HP of converter power. The input can be 1 or 3 phase at 220V, so it works both as a phase converter and as a straight VFD. It uses SPWM control and lists an input frequency of 48-63 Hz. The description mentions an output frequency range up to 3200 Hz and identifies it as a light load model. That is a key thing to weigh: if your motor drives a heavy constant-torque load, the light-load designation means you should confirm the duty match before choosing. For variable-torque applications like fans and pumps, this is a strong contender.
CNC 1 To 3 Phase 220V Variable Frequency Drive Inverter VFD VSD 7.5KW 10HP
Priced at USD 118.92, this CNC-labeled drive gives you the same 7.5kW/10HP output class for a lower listed price than the other 7.5kW model. It accepts 1 or 3 phase input at 220V, uses SPWM control, and its description mentions two sets of terminal functions (multiplex terminal) for flexible control connections. The listed output frequency range is 0-50/60Hz and 0-400Hz, which is narrower than the 0-3200Hz range on the other 7.5kW unit. So if your application needs very high output frequencies, the other model's listing may be the better fit. For typical motor speed control and phase conversion in the 10HP class, this drive is a worthwhile pick.
Final recommendation
Match the drive to your input phase and motor size. For a small 1HP single-to-three-phase job, the 750W drive is the least expensive option. For a 2HP motor on an existing 240VAC three-phase circuit, the Mitsubishi FR-D720-070-W1 covers it. For 10HP needs, both large drives work with 1 or 3 phase input; choose the CNC model if you want the lower listed price, or the other model if the wider output frequency range is relevant to your machinery.
