Choosing between two 220V variable frequency drives is not just a matter of finding 1-to-3-phase wording. The motor's required output class, the available supply arrangement, and the way you want to command the drive all matter. For shoppers comparing VFDs, soft starters, and motor controls, this matchup separates a higher-output CNC-oriented drive from a 1HP VFD with a more limited stated working-frequency range.
Quick verdict
The listed prices are $86.40 apart: the Single To 3 Phase 750W 1HP 220V Variable Frequency Drive Inverter VFD/VSD is USD 32.99, while the 1 To 3 Phase 7.5KW 10HP 220V CNC Variable Frequency Drive Inverter VFD VSD is USD 119.39. Let the motor rating and required controls make the decision rather than using price as the only deciding point.
| Comparison point | 1 To 3 Phase 7.5KW 10HP 220V CNC Variable Frequency Drive Inverter VFD VSD | Single To 3 Phase 750W 1HP 220V Variable Frequency Drive Inverter VFD/VSD |
|---|---|---|
| Listed price | USD 119.39 | USD 32.99 |
| Phase and voltage wording | 220V; input listed as 1 or 3 phase | Single-phase AC 220V input; three-phase AC 220V output |
| Stated frequency range | Frequency control range: 0.1-2500.0Hz | Working frequency: 1.0-99Hz |
| Control mode | SPWM | V/F |
Where each product wins
The 7.5KW 10HP CNC VFD is the clearer match for external control references. Its control inputs include 0-5V, 0-10V, 4-20mA, and 0-20mA. That gives it a defined set of voltage- and current-based command methods for a control plan built around those signal types.
The 750W 1HP VFD is the direct match when V/F control is the requirement. V/F is its stated control mode, and its 1.0-99Hz working-frequency range provides a plainly defined operating range for that type of setup.
Product notes
1 To 3 Phase 7.5KW 10HP 220V CNC Variable Frequency Drive Inverter VFD VSD
This drive fits when a control layout calls for the direct operator setting described with arrow controls. It also identifies P+/PR for a braking resistor and U/V/W as output terminals, giving it specific connection labels for a control plan that uses them. One clear limitation is voltage: it is specified for 220V input, so this choice belongs in a 220V electrical setup. The stated 48-63Hz input frequency further defines the power environment for this drive.
Single To 3 Phase 750W 1HP 220V Variable Frequency Drive Inverter VFD/VSD
The Single To 3 Phase 750W 1HP 220V Variable Frequency Drive Inverter VFD/VSD is appropriate when a motor load matches its 750W/1HP rating. Its maximum input current is 3.86A, and the model is FOR T13-750W-H, two concrete identifiers for this particular drive. The stated working-frequency range is 1.0-99Hz. Its three-phase output is listed as AC 220V. Capacity is its key limitation: 750W/1HP does not occupy the 7.5KW/10HP class named by the other drive. It is therefore aimed at a one-horsepower motor-control application rather than a ten-horsepower one when that rating is specified.
Final choice by use case
Choose the 1 To 3 Phase 7.5KW 10HP 220V CNC Variable Frequency Drive Inverter VFD VSD for a motor-control application calling for 7.5KW/10HP, particularly where direct operator controls and P+/PR terminals matter. Choose the Single To 3 Phase 750W 1HP 220V Variable Frequency Drive Inverter VFD/VSD where 750W/1HP is specified, with single-phase AC 220V input and three-phase AC 220V output.
