We Deliver Reliable Products For Our Customers

“Engineered for durability. Designed for performance. Built to support reliable power systems for long-term commercial and industrial applications.”

Alicia Regnier

“After switching to Winshine’s magnetic transformers, our field failure rate dropped noticeably. Stable temperature rise and low noise made a real difference in outdoor projects.”

Mark Reynolds, Product Manager,

BrightPath Lighting (USA)

“So far good on testing.

Will share info and progress on outreach.”

“I guess I should say why did it take me so long to find you guys? I am working with two major appliance companies that we can both hopefully land. There are 5-6 catalog numbers that we will need to build but right now I need those and a 230 volt model. The 230 volt model is most critical. Thank you”
