If you’re running a shop with three-phase equipment but only have single-phase power available, you’ve probably run into some headaches. Installing utility-provided three-phase power can be ridiculously expensive, but luckily, phase conversion is a solid alternative.
In this article, we’ll break down the different types of phase converters and take a close look at Phase Technologies‘ Phase Perfect digital conversion technology—a game-changer in this space. Whether you’re setting up a new shop or upgrading your power setup, this guide will help you make an informed decision.

Why Three-Phase Power Matters
Three-phase power is the gold standard for industrial and shop equipment. Here’s why:
- Motors run more efficiently and last longer
- Provides more power with smoother operation
- Requires smaller wires, reducing installation costs
- Compatible with a wider range of machines
The problem? Most small shops and home workshops don’t have access to utility-supplied three-phase power. Running new lines can cost anywhere from tens of thousands to over a million dollars, depending on location and infrastructure. That’s where phase conversion comes in.
Different Ways to Get Three-Phase Power
If you need three-phase power but don’t have access to it, you’ve got a few options:
1. Static Phase Converters
Static phase converters are the cheapest option, sometimes as low as $100. They use capacitors to generate a third phase for motor startup, but after that, the motor runs on only two legs. The downsides?
- You only get about two-thirds of the motor’s rated power.
- Increased wear and tear due to uneven torque.
- Not great for anything beyond light-duty use.
2. Rotary Phase Converters (RPCs)
Rotary phase converters use a spinning idler motor to generate a third phase, offering more stability than static converters. These have been a go-to solution for years, but they come with some drawbacks:
- The voltage on the manufactured leg can fluctuate.
- They’re loud and generate heat.
- They take up a lot of space and sometimes require concrete pads for installation.
- They constantly use power, even when idle.
3. Variable Frequency Drives (VFDs)
VFDs are great if you only need to run a single motor, and you want variable speed control. They work by converting single-phase power into three-phase while allowing you to adjust motor speed. Sounds great, but there’s a catch:
- Not practical for machines with multiple motors or complex electronics.
- Often requires modifications to your existing setup.
- More of a niche solution than an all-purpose fix.
The Modern Solution: Phase Perfect Digital Phase Conversion
If you’re looking for the best way to get three-phase power without the drawbacks of traditional converters, Phase Perfect by Phase Technologies is your answer.
What Makes Phase Perfect Different?
Unlike rotary converters, Phase Perfect is solid-state—which means no moving parts, low noise (quieter operation), and no wasted energy. It’s designed to work like true three-phase power, making it perfect for any shop setup.
Here’s why it stands out:
- Voltage stays balanced within 2%—better than most power companies provide.
- Minimal energy loss, even when idle (just a few hundred watts vs. thousands in a rotary converter).
- Powers multiple machines at once, just like utility-supplied three-phase.
- Compact, lightweight, and easy to install.
Choosing the Right Phase Perfect Model
Phase Technologies offers two main product lines, depending on your shop’s needs:
Enterprise Series
- Ideal for setups requiring 7.5 to 20 HP.
- More compact and budget-friendly.
- Delivers the same high-quality power conversion as the Performance Series.
Performance Series
- Covers a broader range: 7.5 to 175 HP.
- Built for higher power demands and more customization.
- Includes extra options like service-rated disconnects and surge protection.
Our Experience with Phase Perfect
At Ultimate Reloader, we’ve put Phase Perfect to the test in two different shop setups:
- Mountain Shop: We swapped out a 20 HP rotary converter for a PTE 010 (10 HP Phase Perfect). Same power rating, but better efficiency and performance.
- Main Shop: With a dedicated 200-amp panel, we installed a PT 030 (30 HP Phase Perfect) to handle future CNC expansions. Now we have rock-solid, clean three-phase power without the hassle.
The Best Choice for Your Shop
If you need reliable three-phase power without the noise, inefficiency, and bulk of rotary converters, Phase Perfect is the way to go. It’s the closest thing to having utility-supplied three-phase power—without the massive installation cost.
Bonus: Get an Extra Year of Warranty!
If you decide to go with Phase Perfect, mention Ultimate Reloader when you buy, and you’ll get an extra year of warranty coverage—for free!
