The Buying Decision
If you are choosing between these two motor controls, the real question is what you are trying to run. The price spread is wide: $50.00 for the SANYO DENKI controller and $229.99 for the LEESON VFD. They are not competing for the exact same slot in the VFDs, soft starters, and motor controls lineup. One is a compact fan/motor controller. The other is a more fully specified AC motor control with defined input and output specs. Matching the control to the motor you actually need to drive is the only way to make sense of these two options.
Quick Verdict
If your project is a fan or motor speed-control job and a simple controller will do, the San Ace is the direct match. If you need a VFD to vary the speed of a small AC motor, the Leeson 174264.00 is the more capable unit.
Side-by-Side
| Product | Price | Price bar | Key details |
|---|---|---|---|
| San Ace PWM Controller | $50.00 | Used SANYO DENKI industrial fan/motor controller aimed at OEM laser applications | |
| Leeson Adjustable Speed AC Motor Control 174264.00 | $229.99 | New open-box LEESON VFD, 120V input, 0-230V output, 2.4A output, 1/2 HP |
Where Each Product Wins
- San Ace wins when a basic controller is enough for your fan/motor application.
- Leeson wins when you need a VFD with the capability to vary motor speed.
- The choice is not about one brand being better than the other; it is about matching the control style to the motor you have.
San Ace PWM Controller - SANYO DENKI - Industrial Fan / Motor Control - OEM Lase
The San Ace controller is a SANYO DENKI PWM unit designed for industrial fan and motor speed control, with an OEM laser application in mind. That makes it a direct option if you are regulating a fan inside laser equipment or another OEM-style assembly. The used condition is the main limitation, so you are purchasing a pre-owned component rather than a sealed unit. If that trade-off is acceptable, the San Ace gives you a straightforward way to get speed trimming on a fan/motor without taking on a more complex VFD setup. This is not a VFD and does not try to be one.
Leeson Adjustable Speed AC Motor Control 174264.00 Industrial VFD
The Leeson 174264.00 is the more defined product in this pairing. It is a new open-box VFD rated for 1/2 HP, with 120V input and a 0-230V output at 2.4A. That set of specs makes it a stronger candidate for a small AC motor that needs genuine speed variation. The open-box condition is the only real caveat: the unit is unused, but the packaging may show that it has been opened. If your motor is larger than 1/2 HP, this VFD's rating is not a match. For a small motor application, the Leeson gives you a clear model number and a horsepower rating to work with.
Final Choice by Use Case
Use the San Ace when you want a simple controller for a fan/motor assembly. Use the Leeson when your motor needs the kind of speed variation that a VFD is designed to provide. If you are still deciding, look at the motor nameplate first; that will settle which of these two motor controls belongs in your project.
