This document applies to any equipment intended to supply or receive charging or operating power from external Information and Communication Technology (ICT) interfaces using ICT wiring or cables. It covers requirements for circuits that are designed to transfer DC power through an ICT interface from a power sourcing equipment to a powered device for equipment that uses interfaces at voltage not exceeding 60 V DC and:
– PDs at power exceeding 15 W;
– PSEs outputs at power exceeding 100 W under any of the following conditions: normal operating conditions, abnormal operating conditions or single fault conditions.
NOTE 1 A PSE or PD which utilize an industry standard connector with a non-industry standard ICT power delivery specification (e.g. protocol) is considered still in scope of this document as determined above.
PSEs are out of scope of this document when the output power is limited to 100 W under all of the following conditions: normal operating conditions, abnormal operating conditions and single fault conditions.
Examples of equipment interfaces that are considered to be within the scope of this document:
– PoE;
– USB Type-C®[1] with USB Power Delivery (USB PD)
NOTE 2 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 with a battery.
Non-static power source and static power source 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 or remote ICT interface;
– power sources with custom connectors that are not interchangeable with common ICT interface connectors;
– non-static power source which can deliver power to multiple PDs through a single port or cable simultaneously;
– power sources with only wireless power transfer;
– power sources which utilize a wireless communication protocol 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[2].
NOTE 3 A custom connector is a connector that is not defined and referenced for use in an industry communication standard.
NOTE 4 Bluetooth®[2] is an example of a wireless communication protocol to control the power transfer through a physical cable connection.
Refer to Annex A for examples of common interfaces which are in or out of scope of this document.
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.
