UL 1876:2015 PDF Download

The UL 1876:2015 standard pertains to the requirements for isolating signal and feedback transformers used in electronic equipment. These transformers are specifically designed to transform audio, video, and other signal waveforms and provide isolation from circuits that are connected to a branch circuit supply or involve voltages that pose a risk of electric shock.

The standard aims to ensure the safety and reliability of these transformers by establishing specific requirements for their construction and performance. It includes criteria related to insulation, dielectric strength, temperature rise, and other electrical properties. Compliance with these requirements is necessary to ensure that the transformers effectively isolate circuits and prevent the occurrence of electric shock hazards.

It is important to note that the UL 1876:2015 standard does not apply to transformers and motor-transformers that are used to power secondary circuits by being connected to a supply circuit. These types of transformers are governed by different standards and requirements.
