Phase-A-Matic
In 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 requirements.
He 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 himself full time to the manufacturing 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.
In 1982 the company was incorporated as Phase-A-Matic, Inc. At that time a line of Rotary Phase Converters was added to our line of products. Through innovative manufacturing techniques we have been able to continue to provide a high quality product at an economical price.
