Why the GP20NLT Transformer Package
Phase converter and step-up transformer are factory-matched and sized together. No guesswork — just connect to your 230V service and run 460V equipment.
Clean, balanced 460V three-phase power from your single-phase supply. Properly sized transformer ensures full voltage under load.
One package powers your entire shop — up to 20 HP of simultaneous three-phase load across all your 460V equipment.
Thermal and magnetic protection safeguards your equipment. AutoLink soft-start system prevents inrush damage on startup.
Continuous duty rated. TEFC motor handles 24/7 operation in demanding environments — dust, heat, and vibration.
A fraction of the cost of running new three-phase service to your facility. Install in hours, not weeks.
IP65 Weatherproof Control Panel
Every panel is rated IP65 — fully sealed against dust and water jets. Install indoors or outdoors with confidence, even in harsh shop environments.
Heavy-Duty TEFC Idler Motor
Totally Enclosed Fan Cooled motor with cast iron frame, precision-balanced rotor, and sealed bearings. Built for decades of continuous industrial service.
🏗️ Common Applications for 20 HP Transformer Packages
The GP20NLT package is commonly used to power 460V three-phase equipment in shops, farms, and industrial facilities with only 230V single-phase utility service.

Talk to an engineer — we'll size the right transformer package for your exact setup
The GP20NLT is a 20 HP phase converter and transformer package designed and manufactured by Phoenix Phase Converters in Phoenix, Arizona. This complete solution converts single-phase 230V power to three-phase 460V using a factory-matched rotary phase converter and step-up transformer. Ideal for facilities that need 460V three-phase power but only have 230V single-phase service available.
Unlike buying a converter and transformer separately, the GP20NLT package ensures proper sizing and compatibility between components. The transformer is rated to handle the full output of the phase converter under load, preventing voltage drop and ensuring reliable operation of your 460V equipment.
