A 200 HP phase converter converts single-phase electrical service into balanced three-phase power for large industrial and commercial operations.
These systems are commonly used to run full production lines, large compressors, pumps, and high-demand manufacturing equipment when utility three-phase power is not available.
American Rotary systems are engineered to deliver balanced voltage, strong starting torque, and reliable three-phase power for the most demanding applications.
A typical 200 HP phase converter can power loads up to approximately 100 HP depending on the starting load and electrical configuration.
For higher horsepower requirements, these systems are typically configured using multiple rotary units operating in parallel, engineered to match the required load, starting characteristics, and installation environment.
American Rotary offers 200 HP phase converter systems designed for facility-wide power requirements and heavy industrial applications.
Whether you are powering multiple production lines, large CNC machining centers, or a combination of high-demand systems, these converters provide reliable three-phase power from single-phase electrical service.

A 200 HP phase converter is typically used as a facility-level power solution in large manufacturing plants, processing facilities, and heavy industrial environments.
Common types of equipment that can be powered include:
The actual capacity depends on the starting load of the equipment and the available single-phase electrical service.
Yes. These systems are specifically designed to power multiple machines, production lines, or entire sections of a facility.
As long as the combined electrical load stays within the system’s rated capacity, multiple processes can operate simultaneously or in sequence.
Phase converters are typically sized using a 2:1 guideline, meaning the converter capacity should be about twice the horsepower of the largest motor you need to start.
For example, a 200 HP phase converter may be used to start a motor around 100 HP, depending on the starting load and equipment type.
Other factors that influence sizing include:
At higher horsepower levels, rotary phase converters are designed as parallel systems to ensure performance and reliability.
A 200 HP system typically uses four units operating together, which allows:
The electrical requirements for a 200 HP phase converter depend on the input voltage and installation setup.
Systems of this size require substantial single-phase electrical service and properly engineered infrastructure. It is recommended to work with a qualified electrician or phase converter engineer to evaluate your installation.
