Need a transformer paired with a phase converter? We’ll design the complete system.

This three-phase transformer converts 240V Delta to 208Y/120V, providing a Wye secondary with a true neutral connection. This is the solution for facilities with 240V Delta three-phase service that need 120V single-phase for lighting, receptacles, and controls. The Wye secondary also provides 208V three-phase for equipment rated at that voltage.

Commonly paired with Phoenix Phase Converters rotary phase converters to create a complete single-phase to three-phase 208Y/120V power system. Available in 15, 30, 45, 75, 112.5, 150, 225, 300, and 500 KVA sizes. Call (800) 417-6568 for sizing help or complete system design.
