Why Phoenix vs. Competitiors?
Not all phase converters are created equal
| Phoenix | Others | |
|---|---|---|
| Warranty | ✓ Lifetime | 1-2 years |
| Motor Type | ✓ TEFC Premium | Open drip-proof |
| Enclosure | ✓ NEMA 4 Steel | Thin sheet metal |
| Tech Support | ✓ US-based experts | Email only |
| Voltage Balance | ✓ ±3% guaranteed | ±10% typical |
| Ships From | ✓ 12 US warehouses | 2-4 weeks lead time |
Pro tip: Cheap converters often damage CNC machines and voids equipment warranties. The $200 you save now could cost $5,000+ in repairs.
