IEC 62368-3 applies to equipment intended to supply and receive operating power through communication cables or ports. It covers particular requirements for circuits that are designed to transfer DC power from a 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. EXAMPLES - For power transfer using voltages at ES1: USB, PoE, ISDN S0, etc. - For power transfer using voltages at ES2: analogue telephone during ringing, ISDN U, etc. - For power transfer using voltages at ES3: power feeding used by communications service providers and utilities communication circuits (for example, RFT circuits, such as line powered HDSLx, SHDSLx, VDSLx and G.fast). This group safety publication is primarily intended to be used as a product safety standard for the products mentioned in the scope, but shall also be used by technical committees in the preparation of standards for products similar to those mentioned in the scope of this standard, in accordance with the principles laid down in IEC Guide 104 and lSO/lEC Guide 51. One of the responsibilities of a technical committee is, wherever applicable, to make use of basic safety publications and/or group safety publications in the preparation of its publications.
