Before you buy a variable-frequency drive, you need to match it to both your motor and your incoming power. The Schneider ATV212HD11M3X is a heavy Altivar drive, while the 1 to 3 Phase VFD is a compact single-phase-input inverter. They are not interchangeable, so the right choice comes down to horsepower, phase, and price.
Quick verdict
If your motor is in the large power class, the Schneider ATV212HD11M3X is the drive to choose. If you have a smaller motor and a single-phase 220V supply, the 1-to-3 phase VFD is the simpler and less expensive option.
Side-by-side comparison
| Product | Listed price | Horsepower | Phase |
|---|---|---|---|
| Schneider ATV212HD11M3X | $350.00 | 15 HP | 3-phase |
| 1 to 3 Phase VFD Inverter 2.2 KW | $65.83 | 3 HP / 2.2 kW | 1-phase input to 3-phase output |
Don't choose solely on price. The drive has to be able to cover the motor's load, and the least expensive unit only makes sense if its capacity is enough.
Where each product wins
Schneider ATV212HD11M3X: This is the stronger choice for heavier industrial loads. It belongs in front of a motor that genuinely needs the larger rated capacity.
1 to 3 Phase VFD: This is the more practical choice for a single-phase feed. It accepts 220V single-phase input and delivers variable-frequency power to a smaller motor, which makes it a convenient way to add speed control without changing the incoming service.
Product notes
Schneider ATV212HD11M3X
The Schneider ATV212HD11M3X is the heavier-duty answer in this head-to-head. It carries a 15 HP rated load and is rated at 46A, so it is built for industrial automation and motion-control applications. If that matches the motor you are controlling, you get the capacity and the Altivar control architecture in one drive. The limitation is the $350.00 price and the scale: if your actual motor is smaller, this drive is far more than the job needs, and you would be paying for rated capacity you cannot use. It is listed as a 3-phase unit, not a 1-to-3 phase converter, so it is not the tool for changing a single-phase feed into three-phase.
1 to 3 Phase VFD Inverter
This compact inverter is the more accessible way to run a small motor from a 220V single-phase line. The product name spells it out: 1 to 3 phase, 2.2 kW, 3 HP. It also has a narrow body design, an independent air duct for heat dissipation, and a keyboard that can be external, making it convenient for cabinet installation and parameter changes. The input current is 23A, and the humidity range is 10 to 95 percent relative humidity. The limitation is capacity: this unit is built for a much smaller motor than the Schneider, so it cannot carry the larger loads. For a smaller motor, it is a sensible fit; for a large one, it is out of its depth.
How to decide
The simplest way to decide is to look at the motor nameplate first. Once you know the motor's horsepower and the phase of your incoming power, one of these drives will be an obvious fit and the other will be too big or too small.
Final choice by use case
- Choose the Schneider ATV212HD11M3X when you need a drive for a larger industrial motor and you want the higher 46A-rated output.
- Choose the 1 to 3 Phase VFD when you have a smaller motor supplied by single-phase power and you want compact, simple speed control.
