1966 Mr. Colin Johnstone, owner of Johnstone Mfg., needed to run
some three phase machines but only had single phase power
available. At that time he was designing and manufacturing
lighting and scorekeeping equipment for NBC Studios for various
game shows, specializing in finding simple solutions to complex
applied this same expertise to the problem of not having the right
power to run his machines. As a result, he developed a phase
converter to run his three phase equipment on his existing single
phase power. He soon noticed that others had need of phase
converters, and by 1968 was producing Phase-A-Matic™ phase
converters as a side line to his other endeavors.
Sales of phase converters increased so rapidly that by the early 1970's he was devoting his full time to the manufacture of phase converters. Expanding his staff and facilities, he could barely keep up with the phenomenal growth in sales. All the while, he continued to make refinements in reliability and
ease of installation of the phase converters.

time a line of Rotary Phase Converters was added to our line of
