Your Dream Shop Shouldn't Be Limited By Available Power
More and more machine shops are being started in rural and other non-industrial areas where three-phase power is not available or is prohibitively expensive. Whether you're setting up in a pole barn, garage, or remote commercial space, the power infrastructure shouldn't limit your machining capabilities or force you to compromise on equipment quality.
THE CHALLENGE: LIMITATIONS OF CONVENTIONAL CONVERSION METHODS
While rotary and static converters offer alternatives to utility three-phase power, they come with significant drawbacks due to poor voltage balance:
Premature Motor Failure:
Other phase conversion methods cannot maintain good voltage balance, causing motors to run hotter—significantly reducing motor life even when temperatures appear acceptable.
Expensive Drive Damage:
Unbalanced power forces rectifier diodes in VFD, spindle, and servo drives to carry excessive current, leading to premature failures and costly complete drive replacements.
Inconsistent Machining Results:
Spindle and drive motor speeds could become unstable during heavy cuts, which can create chatter, poor surface finish and the loss of motor torque can cause unexpected stalling during machining operations.
Frustrating Downtime:
Drives can trip or fault with "DC bus" or "phase loss" errors due to phase imbalance, interrupting production and workflow.
Compromised Precision:
High-precision operations become increasingly difficult due to thermal distortion from unbalanced heating in spindle assemblies—directly affecting part accuracy.
Modern CNC equipment and even conventional machines with electronic controls require significantly better voltage balance than rotary or static converters can provide. Without it, you're compromising not just your equipment longevity, but your shop's productivity and part quality.
THE SOLUTION: PHASE PERFECT®
The Phase Perfect® was specifically designed to address the unique power needs of machine shops. Just feed single-phase into the unit and get utility-quality three-phase back out.
Unlike other types of phase converters, Phase Perfect offers:
Low standby power consumption
- Reducing ongoing operational costs
Utility-grade, true three-phase output
- Ensuring perfect balance for sensitive electronics
Support for multiple simultaneous loads
- Run your entire shop, not just one machine
No moving parts
- Silent, maintenance-free operation
WHY MACHINE SHOPS CHOOSE THE PHASE PERFECT®
True Three-Phase Power:
Provides clean, balanced, and stable three-phase power that meets the tight voltage balance tolerances required by CNCs and sensitive electronics—unlike rotary or static converters.
Power For Hard-Starting Loads:
Ensures dependable operation of high-inertia machines like lathes, mills, and air compressors.
TECHNICAL DETAILS: DESIGNED FOR VERSATILITY
Transformer Friendly:
In many cases, machine shop equipment requires 208V delta configured three-phase power. A Phase Perfect® is easily paired with relatively inexpensive buck/boost transformers to lower voltage to 208V from 240V if required or can be used with a Delta to Wye transformer for applications requiring a neutral.
Reliable:
With over 20 years of refinement, our solid-state converters are built to last: No moving parts = less maintenance, fewer failures. Phase Perfect ensures uninterrupted operation, lower energy costs, and longer equipment life.
Perfect For:
Rural or off-grid locations
Pole buildings, barns, and shops
Equipment change-outs where 3-phase isn't available
Multiple simultaneous loads
THE VALUE: SAVINGS THAT ADD UP
Most importantly, we save you money. No costly utility upgrades, just efficient, reliable power for your shop.

Phase Conversion & Voltage Doubling
Cost Savings for Long Lead Applications
Phase conversion allows three-phase output from a single-phase input, giving you access to three-phase power anywhere. Voltage doubling eliminates the need for a transformer while minimizing motor lead wire size on 460 V systems running on a 230 V source, saving you hundreds on wire costs.
