Rotary phase converters provide a continuous supply of power to heavy-duty equipment used in various commercial, industrial, and residential settings. These machines are necessary when utility three-phase power is either too costly or not available in a certain area. From construction and agriculture to metalworking and food service, industries across the board rely on phase converters to reliably power their equipment for daily operations.

Unfortunately, some phase converters produce excess noise when they run. Other than being annoying and causing disruptions in the workplace, noisy phase converters can raise concerns that something has gone awry internally. Keep reading to learn why some phase converters produce excess noise.

Phase Converter Noise Levels

A common phase converter problem is excessive noise production. Even the most advanced phase converters produce some noise. It’s a reality that can’t be avoided completely. Phase converters are noisy for various reasons, including having outdated or malfunctioning components or being improperly sized for the application at hand. Phase converters that run on a standard three-phase motor are typically louder than those that run on a customized generator built to meet its specifications.

Phoenix Phase Converters Decibel Levels

Understanding how loud phase converters are—both single-phase and three-phase—starts with understanding decibels (Db)—which measure sound by its intensity. All of our phase converter models produce 43 Db from ten feet away. That’s the average noise in a room of people.

For context, here are additional Db levels and their common noise comparisons:

  • 20 Db: a ticking watch
  • 30 Db: a whisper
  • 60 Db: a running box fan
  • 75 Db: landscaping equipment (from indoors)

Our phase converters are designed to run smoothly and quietly during each use. That’s because they’re integrated with cast-iron generators that produce minimal noise, equivalent to or less than the sound level of a motor with the same horsepower as the load. They also have relatively low running speeds, which creates less noise.

Is Your Phase Converter Excessively Loud?

While it’s normal for a phase converter to create some noise, excessive noise production can indicate an issue with the unit—like inefficient operation or internal damage. Below are some common noises that malfunctioning phase converters make, along with troubleshooting tips.

Grinding or Growling

  1. Open Circuit: Check the fuses, breakers, starters, and switches for an open circuit.
  2. Incorrect Wiring: Ensure the wiring is installed and functioning properly.
  3. Excessive Load: Ensure your phase converter can handle the power load placed on it.

Humming or Chattering

Consistent low voltage means the phase converter is too small for the application. Switch out the phase converter for a more accurate size.
