Choosing a variable frequency drive isn't just about comparing specs. You have to decide between paying more for a used industrial drive from a specific line, or paying less for a new unit that works as a phase converter and speed controller. The two drives here sit at opposite ends of that trade-off.
Quick Verdict
If you want a new drive that turns your single-phase shop power into three-phase output and you're watching your budget, the CNC 7.5KW 10HP VFD is the practical pick. If you need the Control Techniques Unidrive SP platform and you're comfortable with a used, as-is industrial drive, the Vortek SP1406 is the one to consider.
Price and Key Details at a Glance

Where Each Product Wins
- The Vortek SP1406 wins if you want the Control Techniques Unidrive SP platform and are prepared for used, as-is gear.
- The CNC 7.5KW wins if you want a new, lower-cost drive with a 1-to-3 phase 220V setup and a wide speed range.
Product Notes
Vortek SP1406 Unidrive SP
This is a used Control Techniques drive from the Unidrive SP family. It was removed from a working environment, so it's a used industrial unit rather than a new VFD. Choose it if you specifically need the Unidrive SP platform and you're building a system around that Control Techniques line. The limitation is the condition: it's sold as-is, and you should not assume it works unless the seller states otherwise. Only the pictured items are included, so you may need to source any missing wiring or accessories yourself before putting it into service.
CNC 7.5KW 10HP VFD
The new CNC 7.5KW 10HP drive from findmall is the lower-priced option. It uses SPWM control and comes with a frequency range up to 400Hz. It is intended for constant and variable torque loads such as pumps, fans, and compressors. Choose it if you want a new unit for a 220V motor. The main limitation is the input voltage: it's a 220V drive, so a 110V shop circuit will need an external step-up transformer before this VFD can operate.
Final Choice by Use Case
For a VFD under $120, the CNC 7.5KW 10HP is the straightforward pick. For a Control Techniques drive with a $360 budget, the Vortek SP1406 is the one to consider. If you're on a tight budget and want new gear, go with the CNC. If you already know you want the Unidrive SP platform, spend the extra on the Vortek.
