This HVAC-grade rotary phase converter is designed specifically for compressor motors in air conditioners, heat pumps, freezers, and refrigeration systems. Compressors have high locked-rotor amps (LRA) on startup — this converter is sized to handle that inrush without tripping breakers or damaging your compressor. Includes a built-in Digital Phase Shifter (DPS) for balanced voltage output.

Why HVAC-Grade Matters
Compressors draw 5–6× their running amps on startup (LRA). This converter is oversized to handle that inrush — won't trip breakers or brownout.
Built-in DPS provides tighter voltage balance across all three legs. Compressors run cooler, more efficiently, and last longer with balanced power.
Overload and short-circuit protection prevents compressor damage. The DPS keeps voltage within the compressor manufacturer's tolerance.
IP65 weatherproof panel installs right next to your condenser unit outdoors. TEFC motor handles heat, rain, and dust without issue.
🏗️ Equipment This Converter Powers
How to find your LRA: Check the compressor nameplate for "LRA" (Locked Rotor Amps). If you only see HP or RLA, call us — we'll calculate the right converter size.
Tell us your compressor model — we'll size the right HVAC-grade phase converter
This HVAC-grade rotary phase converter is engineered for three-phase compressor motors found in air conditioners, heat pumps, walk-in coolers, freezers, and refrigeration systems. Compressors have extremely high locked-rotor amps (LRA) on startup — this converter is oversized to handle that inrush without tripping breakers or damaging the compressor winding.
Every HVAC-grade converter includes a Digital Phase Shifter (DPS) for tighter voltage balance — critical for compressor longevity and efficiency. Manufactured by Phoenix Phase Converters in Phoenix, Arizona, with a lifetime warranty on motor and panel. Select your compressor's LRA or HP from the dropdown above, or call (800) 417-6568 for sizing assistance.
