Phase-a-matic cnc pac-7 converter & voltage stabilizer


Got three-phase machines and only single-phase power? We've got the solution!
PHASE-A-MATIC CNC PAC-7 Phase Converter:
The CNC Package Phase Converters provides balanced voltage necessary for dependable operation of CNC and sensitive equipment. True 3-phase power is delivered with this package of a Rotary Phase Converter and Stabilizer known as a CNC PAC™. Scroll down for more information on the CNC PAC-7 Package.
Most CNC/PLC machines require a CNC PAC™ 1-1/2 to 2 times larger than the spindle motor 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 30,000+ RPM spindles, regenerative braking, etc. These may require a CNC PAC™ even larger. Phase-A-Matic has a large data bank from past applications experience to help you with these decisions so technical support is a breeze!

Reliability, quality and construction of the PHASE-A-MATIC™ Rotary Phase Converter:
Baldor Electric/PHASE-A-MATIC™ Design and Quiet Operation
Simplicity of design; uses all soldered connections
Keeping the design exceptionally simple reduces the risk of electrical connection failure to almost zero since these are some of the most common causes of failure. We use only soldered connections with no mechanical electrical connections like spade clips, terminals or screws which can vibrate loose or corrode over time. There are no start capacitors, relays or contactors with connections which can come loose or arc and weld the contacts causing failure of the contactor and the start capacitors, and perhaps even the rotary converter or your equipment. Because of this we do not have circuit board failures caused by spikes generated by the magnetic contactors as some of our competitors do.
The PHASE-A-MATIC™ failure rate is practically zero because the rotors are specifically designed and manufactured for rotary converter use. [see MTBF below] However, some of our competitors emphasize that rotors often fail. This is because they machine standard electric motors, modifying and thereby weakening standard electric motor rotors, which were not originally designed to be used as a phase converter.
MTBF (Mean Time Between Failure)
Failure rate (MTBF) is so low it's almost impossible to determine. We find that within the first 12 months approximately 1 in 150 might have a problem, and usually within a few weeks or months. After the first 12 months, it might be one or less in 5,000 over a 30 year period. We continue to hear of our Rotary Converters that have been in service for 25 or 30 years, and which are still working flawlessly. It could go on to do another 25 or 30 years. There is very little to go wrong with the Rotary Converter.
The most likely warranty repair would be bearings or windings, which are very rare. This type of failure is much less than 1%, and if it is going to happen at all, most likely would occur within the first 12 months. Failures after that are extremely rare. See MTBF above.
For use with Rotary Converter for 3-phase electronic equipment such as CNC/PLC machines, AC/DC drives, and all voltage-sensitive equipment. Provides +/- 5% voltage stabilization.
The normal operating voltage of the Rotary Phase Converter is 208-230VAC. The output voltage of the Rotary Phase Converter is normally higher than the input voltage under no load and light load conditions. In applications with high single-phase voltage (greater than 230V), the no load or light load output voltage may be excessive. Some CNC/PLC equipment will not work properly at the higher output voltage.
The Phase-A-Matic™ Voltage Stabilizer is designed to reduce this higher voltage to nearer the input voltage. It will also keep the output voltage stable during peak loads, thus helping CNC/PLC equipment and other voltage sensitive equipment to operate properly.
Running very small motors alone on a Rotary Converter that is 3 times or more larger may not reduce the output voltage sufficiently, in which case the smaller motor may run hot. For these cases, to reduce cost it may be possible to use a dedicated Voltage Stabilizer sized to the requirements of the problem motor only. Consult factory.
Supplied in a NEMA type 1 enclosure with various sizes of knockouts.
Intended for indoor use only in dry locations, but can be placed in a rain tight enclosure for use in wet or damp locations.
