Delta-wye-phase-shift Single-phase-to-three-phase-transformer 40VA Three-phase-to-one-phase-transformer
A delta‑wye transformer introduces a 30° (or 150°) phase displacement between primary and secondary windings. This shift balances line currents, reduces neutral loading, and minimizes harmonic propagation in three‑phase systems—critical for motor drives, medical equipment, and grid‑connected renewable inverters.
Yes. Our R&D team offers full OEM/ODM services: you can specify primary/secondary voltages, current ratings, IP‑rating (IP20‑IP65), and even colour‑coded terminal blocks. Samples are provided within 7 days of design approval.
Standard production runs ship in 14 days after order confirmation. For urgent projects we offer express 7‑day production on the same line, with air‑freight at no extra handling charge.
Every unit is accompanied by a Factory Acceptance Test (FAT) report, CE Declaration of Conformity, UL file, and a full ISO 9001 quality audit record. PDFs are uploaded to our secure client portal.
We accept T/T 30 % advance, 70 % against documents, or L/C at sight. For verified long‑term partners we can extend to 60 days net.
Limited‑time Offer: Free engineering sample (up to 2 kVA) + 30‑day money‑back guarantee.

Mark T., Procurement Lead, Texas Energy Solutions
“The delta‑wye units arrived on schedule, passed all UL tests on first try, and reduced our harmonic distortion from 4.8 % to 1.1 %. The ROI was realized in under 4 months.”
Emily R., Senior Engineer, BioMed Instruments
“Xinchangda’s custom enclosure (IP65) met our clean‑room standards. Their technical support helped us pass FDA 510(k) with zero comments.”
David L., Plant Manager, GreenTech Solar
“Phase‑shifted transformers are the backbone of our inverter farms. Xinchangda’s price‑performance ratio beats European OEMs by 28 % while keeping 99.9 % reliability.”
