BS EN IEC 62368 discusses audio/video, information, and communication technology equipment. BS EN IEC 62368-3 is the third part of the multi-series on audio/video, information, and communication technology equipment that provides safety aspects for DC power transfer through communication cables and ports.
BS EN IEC 62368-3 applies to equipment intended to supply and receive operating power through communication cables or ports. BS EN IEC 62368-3 covers particular requirements for circuits that are designed to transfer DC power from power sourcing equipment (PSE) to a powered device (PD).
Note 1: ES1 can generally be assumed to have similar limits as non-hazardous voltage definitions used in other standards (for example, SELV, PELV).
Note 2: ES2 can generally be assumed to have similar limits for single fault conditions as non-hazardous voltage definitions used in other standards.
Note 3: PS2 circuits are generally expected to provide less than 100 W to an undefined load under both normal operating conditions and single fault conditions.
BS EN IEC 62368-3 on audio/video, information, and communication technology equipment is useful for:
To ensure user- safety, BS EN IEC 62368-3 on communication technology equipment safety specifies what is an acceptable voltage and the type of protection needed.
BS EN IEC 62368-3 provides requirements for circuits that are designed to transfer DC power from power sourcing equipment (PSE) to a powered device (PD). The power transfer uses voltages at ES1 or ES2 or, in very specific cases, voltage levels at ES3. One of the responsibilities of a technical committee is to make use of basic safety publications and/or group safety publications in the preparation of its publications.
