UL Recognised

Underwriters Laboratories : Recognised Components

UL recognised transformers Nuvotem Talema offer UL recognised components to several UL Standards.
Our factories are audited regularly to ensure compliance.
Our UL "Follow Up Services" or "FUS" is our detailed agreement with Underwriters Laboratories which ensures our products meet the relevant standards.
