Designed especially for 3-phase CNC/PLC machines operating from single-phase power source and provides the balanced voltages necessary for reliable operation. 4-Year Warranty.  

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 3-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.

Most CNC/PLC machines require a CNC PAC 1½ to 2 times larger than the spindle motor in order to accommodate the extra amps for starting, instant reversing, and for the servos, hydraulics, etc.

Later model CNC/PLC machines are more technologically sophisticated, with up to 10,000 RPM and higher spindle speeds, regenerative braking, etc. These may require the CNC PAC sized even larger. We have a large data bank from past applications experience to help you with these decisions.

Note: 220V CNC PAC is 220V single-phase in and 220V three-phase out. 460V CNC PAC is 460V single-phase in and 460V three-phase out.
