Reliable Power Solutions

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.”

Joe

“Your transformers are very good and we like them.Thank you.”

John

“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”

Steve

“The consistency of Winshine’s M Series is what impressed us most. Batch-to-batch stability is critical for our landscape lighting systems.”

Alex , Operations Manager,

El,

“Winshine is not just a supplier — their engineering team helped us match transformers to real outdoor conditions, reducing returns and customer complaints.”
