IEC 62368-3 Audio, Video, Information and Communications Technology Equipment - Part 3: Safety Aspects for DC Power Transmission via Communication Cables and Ports

The IEC 62368-3 standard applies to equipment intended to supply and receive operating power through communication cables or ports. It covers specific requirements for circuits designed to transfer DC power from a power supply equipment (PSE) to a powered device (PD).

IEC 62368-3 Audio, Video, Information and Communications Technology Equipment - Part 3: Safety Aspects for DC Power Transmission via Communication Cables and Ports

The power transmission uses voltages at ES1 or ES2, or in very special cases voltage levels at ES3.

Any cable supplied with a connector defined by an industry standard that allows DC power transfer between equipment is considered a communication cable even if communication does not occur. For example, a USB cable can be used to charge the battery of a portable device.

This International Standard will be used in conjunction with IEC 62368-1:2014.
It has group safety broadcast status according to IEC Guide 104. Subclauses of IEC 62368-1 apply to the extent reasonable. Where safety considerations are similar to those of IEC 62368-1, the relevant article or subclause of IEC 62368-1 is referenced in a note in that subclause.

Where a requirement in IEC 62368-3 refers to a requirement or criterion of IEC 62368-1, specific reference is made to IEC 62368-1.

This group safety publication is primarily intended for use as a product safety standard for products specified in the scope, but will also be used by technical committees in the preparation of standards for products similar to those specified under this standard.

Our organization, among numerous test, measurement, analysis and evaluation studies, with its trained and expert staff and advanced technological equipment, within the framework of national and international standards, IEC 62368-3 Audio, Video, Information and Communication Technology Equipment - Part 3: Provides Safety Aspects testing services for DC Power Transmission Via Communication Cables and Ports.
