PHASE-A-MATIC™ has been successfully providing phase converters since 1965, and for CNC machines from the time they were first introduced into service in the U.S.A.

A Rotary Phase Converter, Voltage Stabilizer.combination, when properly sized, provides the necessary voltage balance of close to +/- 5% or less between legs compared to standard three phase line voltage of +/- 10%. It also helps to keep the output voltage stable during peak loads, thus helping most CNC/PLC and other voltage sensitive equipment to operate properly.
