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 PhaseAMatic™ phase converters as a side line to his other endeavors.
