Why the GP40PLTA Phase Converter
The Autolink transformer converts 230V three-phase to 460V three-phase internally — no external transformer box needed. Cleaner installation, smaller footprint.
Clean, balanced 460V three-phase power from your single-phase supply. Won't damage sensitive equipment or trip breakers under load.
One phase converter powers your entire shop — up to 40 HP of simultaneous three-phase load across all your 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.
Integrated Autolink design eliminates the cost and complexity of a separate step-up transformer. One unit does it all.
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 40 HP Phase Converters
The GP40PLTA is commonly used to power 460V three-phase equipment in shops, farms, and industrial facilities running on single-phase 230V utility service.

The GP40PLTA is a 40 HP rotary phase converter with built-in Autolink transformer, designed and manufactured by Phoenix Phase Converters in Phoenix, Arizona. This single phase to three phase converter provides reliable 460V three-phase power from a standard 230V single-phase service, with integrated step-up voltage conversion. No external transformer is needed — the Autolink system handles the voltage conversion internally, simplifying installation and reducing costs.
The PLTA series is ideal for facilities that need 460V three-phase power but only have access to 230V single-phase service. Common applications include CNC machines, air compressors, pumps, HVAC systems, and other industrial equipment rated for 460V operation.
