Single-phase HVAC equipment is generally limited to around 5 tons (60,000 BTU) in capacity. For larger homes, custom builds, and light commercial applications, the industry standard is three-phase power. Most high-efficiency rooftop units, VRF systems, and large-capacity air handlers are only manufactured in three-phase configurations.

But what happens when your site doesn't have access to three-phase utility service? That's where Phase Perfect® steps in. The Phase Perfect® digital phase converter is the gold standard for HVAC applications, converting single phase to three phase while providing multiple load support and maintaining near-perfect voltage balance under all conditions.

Unlike other types of phase converters, Phase Perfect offers:

1. Access Commercial Equipment Anywhere

Power rooftop units, scroll compressors, VRF systems, and multi-stage blowers even in rural areas.

2. Clean, Balanced Power

Maintain near-perfect voltage balance across all phases, even with variable loads.

3. Easy Installation

Install inside or outside. No programming required.

4. Silent, Reliable, Efficient

No noisy rotary motors or regular maintenance.

5. Scalable for Any System

Supports systems rated to 200 MCA or higher, able to power even the largest packaged RTUs.

The Phase Perfect® powers virtually any three-phase load, wherever you are:

Traditional utility extension can cost tens, sometimes hundreds, of thousands of dollars. With Phase Perfect, you get utility-grade power at a fraction of the cost—with zero infrastructure delays.

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.
