Phase Perfect vs. Everything Else.
Stop wasting money on lost power and burned-out motors. Enter your load size and the hours per day you are working with your equipment to see what you’re spending with a rotary converter and how much you’ll save with a Phase Perfect today.
Calculations assume $0.20/kWh. Phase Perfect idles at 80W; a comparable rotary idles at ~11% of rated HP. Check your regional rate →
| Feature | Phase Perfect® Digital Converter | Rotary Converter | Static Converter |
|---|---|---|---|
| Running Efficiency | 98.7% | ~87% — 13% wasted as heat | ~50% — only powers 2 of 3 windings |
| Voltage Imbalance | <2% — utility standard | 3–8% — stresses motors | High — only 2 phases are powered |
| Standby Power Draw | 80W — barely anything | 2,000–4,000W+ | Low |
| Noise Level | Near silent — no moving parts | Loud — always spinning | Silent |
| Motor Power Output | 100% — all three phases powered | ~85% — voltage imbalance reduces output | ~50–65% — motors run hot & weak |
| Motor Life Impact | Full life — clean balanced power | Reduced — imbalance causes heating | Significantly reduced — runs hot |
| Multiple Machines | Run several simultaneously | Yes, if sized correctly | One machine at a time |
| Maintenance Required | None — fully solid state | Capacitors every 1–3 years | Occasional capacitor check |
| Built-in Protection | Digital fault monitoring | None | None |
| Yearly Operating Cost (10 HP) | ~$24/yr | ~$1,700/yr | ~$12/yr idle, but motors wear faster |
| Starting and Load capacity | 20 HP | 40 HP Required (2× Oversized) | — |
| Physical Presence | Compact, Lightweight, Quiet | Large, Heavy & Loud | — |
| Monitoring & Controls | Built-In Display, Keypad & Modbus | None | — |
| Regenerative Technology | Returns Energy During Shutdown | Wasted Energy / No Regeneration | — |
| Installation | 2 Wires In, 3 Out | Complex Wiring Required | — |
| Enclosure | Low Cost NEMA 3R Available | $$$ Expensive 3R | — |
Run 460 V three-phase equipment off standard 230 V single-phase service — no transformer required. Available in 20 HP and 30 HP configurations.
