Standards Development

Scope

This document applies to any equipment intended to supply or receive charging or operating power from Information and Communication Technology (ICT) interfaces using ICT wiring or cables. It covers particular requirements for circuits that are designed to transfer DC power through an ICT interface from a power sourcing equipment (PSE) to a powered device (PD) for equipment that uses rated interfaces at voltage not exceeding 60 V DC and power exceeding PS1.

Examples of equipment interfaces that are considered to be within the scope of this document:

– PoE;

– USB;

– HDMI;

 – etc.

NOTE 1 Any wiring or cable that permits DC power transfer between ICT equipment is considered a communication cable or ICT cable even if communication does not take place on the conductors. For example, a USB cable can be used just to recharge a portable device battery.

PSE and PD using other power delivery specifications that differ from the industry standard power delivery specification defined for use with the industry standard connector are in the scope of this document.

Non-static power sources (3.12) and static power sources (3.13) are covered in this document.

Unless otherwise stated, this document does not cover:

– power sources with output connectors not associated with a local ICT interface (3.9) or remote ICT interface (3.11);

 – power sources with custom connectors that are not interchangeable with common ICT interface connectors;

– non-static power sources (3.12) which can deliver power to multiple PDs (3.3) through a single port or cable simultaneously;

 – power sources with only wireless power transfer;

 – power sources which utilize a wireless communication protocol (3.10) to control the power transfer through a physical cable connection;

– remote feeding telecommunication (RFT) circuits and other specific communication technologies within the scope of IEC 63316.

NOTE 2 A custom connector is a connector that is not used with an industry communication standard.

NOTE 3 Bluetooth® is an example of a wireless communication protocol (3.10) to control the power transfer through a physical cable connection.

Refer to Annex E for examples of common interfaces which are in or out of scope of this document.

Purpose

This standard is intended to be a group safety publication in conjunction with IEC 62368-1 and other safety standards covering equipment that has ICT interfaces which provide or receive power at 60VDC or less. It is intended to replace IEC 62368-3 Section 5 with new protocol safeguards to address newer non-static power delivery methods.
