About Kay Industries
Kay Industries, Inc., is the worldwide industry leader in designing, manufacturing, and marketing the three phase converter known across the global as the Phasemaster®. A privately held corporation, Kay Industries sells single-phase to three-phase electrical power converters nationwide in the U.S. and exports to Central and South America and the Pacific Rim. Kay Industries, Inc., markets under the registered trademark Phasemaster®and is headquartered in Nappanee, Indiana, with offices in Plymouth, Indiana and Fremont, California.
Kay Industries, Inc., was the first phase converter company to offer:
Rotary converters (1960)
Automatic controls (1972)
Money-back performance guarantee (1975)
Independent agency approval (CSA/NRTL) (1979)
National toll-free lines (1980)
Extended warrantees (1986)
Phasemaster units are manufactured under U.S. Patent Nos. 3349316, 3387202, 3609430 and Canadian Patent No. 786933
Alternating current power is a form of electricity in which power flows constantly in changing directions is nothing new. Since the early 1900’s, AC has been the form of power used in homes and businesses. However, for most businesses and industries, three phase AC power provided by single phase to three phase converters is used because it accommodates higher power loads.
Three phase power consists of 3 power wires and each one of them is 120 degrees out of phase with each other. Wye and delta are the circuits used to maintain equal loads in a rotary phase converter.
In delta configuration, neutral wire is not used. On the other hand, wye configuration uses both ground and neutral wire. In a single phase to three phase converter system, all three phases usually enter the cycle at 120 degrees.
We guarantee the features, workmanship, finish, and overall appearance of the Phasemaster® will be superior to any other brand on the market or any you have ever seen.
We guarantee a Phasemaster converter will cost no more than any other converter of the same physical frame size.
We guarantee a Phasemaster converter will be quieter than any other make of rotary.
We guarantee a Phasemaster converter will do the job it was purchased to perform and will operate your load at its full rated capacity.
If the Phasemaster converter does not meet these claims, you may exchange it for a different model or return it for full credit.

However, when they complete the cycle of 360 degrees, each phase will have peaked twice voltage. The main difference between single phase and three phase is constancy of delivery. In single phase, power is not delivered at a constant rate. On the other hand, three phase power provided by single phase to three phase converters provides a steady stream of power that is delivered at a constant rate. This makes three phase power from rotary phase converters reliable and fully capable of accommodating heavier loads.
The owners of Kay Industries, Arco, and Ronk all made earlier contributions towards the advancement of the three phase converter from a rotary sense.
