Scenario 1 – Premium Aftermarket Audio Kits
OEM X incorporated our toroidal transformer into a 5‑channel kit, achieving a 32 % weight reduction and a 25 % boost in SPL without redesigning the chassis. Launch time shortened from 8 weeks to 4 weeks.
Scenario 2 – OEM Vehicle Integration
Major US automaker selected Xinchangda for a fleet of 120k electric‑vehicle models. Our 150 W units met the automaker’s stringent VDE‑approved EMI standards, resulting in zero warranty claims for the first 12 months.
“Switching to Xinchangda’s toroidal transformer cut our amplifier weight by 28 % and saved $0.45 per unit. Delivery was on‑time, and the CE certificate cleared customs instantly.”
All products are certified: CE, FCC, RoHS, CB, ISO 9001. Our factory complies with ISO 14001 environmental standards and holds a VDE safety audit report (2025).
Act within 7 days and receive a 5 % discount on the first purchase, plus a 30‑day money‑back guarantee if the transformer does not meet your spec.
Laura M., Technical Director, AutoAudio USA – “The Xinchangda toroidal transformer reduced our chassis size by 22 % and passed FCC testing on the first try. Delivery was 3 days faster than promised.”
Tom R., Procurement Lead, SoundForce Inc. – “We saved $0.38 per unit and the unit‑to‑unit consistency is flawless. Their engineering support cut our design cycle by 40 %.”
Emily S., Operations Manager, CarAmp Pro – “Free sample arrived within 4 days, and the performance matched the datasheet. We placed a 10 k‑unit order the same week.”
