Phase Converter Comparisons

We take the confusion out of comparing Phase ConvertersWith so many types of phase converters and different manufacturers giving you different information, it doesn't take long before you become very confused to what type of phase converter you need.

We have taken all the phase converters and rated them on three catalogues in an effort to help you in your choice: 

  • Producing true balanced 3-phase power.
  • Phase converter life and durability.
  • Operating and equipment safety.

1. Rotary Converters are our number one choice, because they provide a balanced 3-phase power source by using a balanced 3-phase generator with power factor correction. Due to high quality materials like copper windings, a rotary converter should last indefinitely.  In the industrial field, we still see rotary converters that have been operating for over 50 years. By providing a balanced 3-phase power source, they are safe to operate and provide protection to your equipment.

2. CNC-Phase Converters are our second choice. The only difference between the rotary-phase converter and the CNC is it provides more balanced power to run sensitive computers that are a part of the CNC machines of today. 

 3. Digital-Phase Converters are the newest technology in phase converters, and we rated them number three, because they tend to be sensitive and are prone to damage if you have a spike from your 3-phase load. Also, they are expensive to repair and have a shorter life expectancy of two to ten years.


4. VFD as Phase Converters  sometimes called phase inverters, are manufactured to control speed and sometimes can be used to run 3-phase motors, but they cannot power any other types of 3-phase loads. They are never used for any type of mixed loads and are very sensitive. They also have a shorter life expectancy because of the capacitors usually lasting two to eight years.

 


We have taken all the phase converters and rated them.

5. Static-Phase Converters have an inability to produce true 3-phase power. Static-phase converters do not actually convert one-phase power to 3-phase power, nor do they generate 3-phase power. Static converters operate by changing and discharging capacitors to produce a third phase of power only a few seconds during the startup of electric motors. Also, by the nature in which they work, they can burnout motors by overheating. They have a short life span of one to two years or less.

6.Build-Your-Own Phase Converter Kits are equivalent to static-phase converters with inferior electric motors as generators and only waste your valuable time and money.

It is our recommendation that rotary-phase converters made with a 3-phase generator and power factor correction are the only true 3-phase balanced power source.

In our research, we have noticed some companies market their products as rotary-phase converters, and all they consist of are control boxes and electric motors. These types of products are no more than a static-phase converter and are rated as such.

Not all phase converters are the same, many of them only convert unbalanced 3-phase power. High quality phase converters are built to last and are reliable.  They are just as efficient as utility 3-phase power.

  When choosing your phase converter, make sure you pick a reliable, quality manufacturer like TEMCo or ACE Phase Converters.Three-Phase Power  Check out their Phase Converters by visiting these companies web sites listed below.
