Each year at Phoenix Phase Converters, we help thousands of people run various machinery using the right phase converters. Our small devices convert single-phase power to three-phase power to meet the power supply needs on a budget. 

Whether it is CNC equipment, welders, or compressors, there are mainly three key areas in which the customers need help. These are: 

  1. Selecting the right phase converter 

  2. Troubleshooting installation issues 

  3. Ensuring efficient performance 

So, this blog is about how we help our customers address these three major types of issues. This will also help you to make the best decision for your machinery setup. 

How to Find the Right Size Phase Converter 

One of the most common queries of our customers is: “What size phase converter should I buy for my equipment?” 

The search for the right size phase converter depends on the horsepower (HP) and amperage of your equipment and machine. You first need to identify these aspects of your machine to move further. 

The right size is important for efficient performance, as undersizing can lead to overheating your equipment and startup failure, while oversizing can cause unnecessary waste of energy and money. 

So, our team helps the customers to identify the appropriate phase converter size to meet their needs by considering the following points: 

  • Load type and horsepower of the motor (resistive, inductive, or mixed)

  • Startup needs (hard start or soft start loads) 

  • Load sequence and duty cycle (constant or intermittent use)

Pro Tip 

You can use dual-zone phase converters, which can separate start and run functions for a cleaner and more stable voltage. These are ideal for sensitive equipment and other precision tools. 

Installation & Troubleshooting: Step-by-Step Support

Selecting the right phase converter is important, but not enough. It should also be installed properly so it won’t cause any trouble. Some of our customers report the following issues because of improper installation: 

  • Phase converter startup issue

  • Breakers tripping under load 

  • The voltage output is irregular 

To address these issues, our experts provided detailed and step-by-step instructions to help them out. These conversations usually cover everything related to the following aspects: 

  1. Correct wiring connections 

  2. Voltage drop testing 

  3. Sizing and protection of breaker/fuse 

  4. Checking grounding and isolation 

Our experts help the customers at every step of the process. This does not require any electrician license, though we always recommend having one in case you are unsure. 


Built for Harsh Environments: Quiet, Durable, and Efficient

Some customers also run shops and farms. Such customers ask for long-term reliability, power consumption, and noise levels. We ensure them that our rotary phase converters offer the following benefits: 

  • Dust and debris resistance 

  • Quiet performance for indoor use 

  • Especially designed for energy efficiency 

All the products of Phoenix Phase Converters are made in the USA with high-quality industrial-grade components. Thus, they offer better performance and value over time than generic or imported models.
