THE COSINUS proposes to you to realize the transformer meeting the standard UL / CSA that you need.


Organization which since 1894, evaluates products for the safety of the general public:


- Extended in 70 countries with nearly 182 laboratories.

- Tests on more than 18,750 categories of electrical, mechanical and chemical products.

- Consumer confidence: products get a true indication of safety.

- Laboratories continue to test products after launch

- Unexpected visits by UL representatives (Quarterly audits), which check whether the safety standards are still maintained

- If the product no longer meets the UL requirements, certification is immediately withdrawn.


Our UL certification covers the electrical insulation system and allows us to apply the official "Underwriters Registered" logo on our products (,+Electrical+Insulation+-+Component&objid=1082869705&cfgid=1073741824&version=versionless&parent_id=1073767046&sequence=1).
