This document
a) addresses the support of safety extra low voltage (SELV) and limited power source (LPS) applications that provide remote power over balanced cabling in accordance with the reference implementations of ISO/IEC 11801 series standards using currents per conductor of up to 500 mA and targets the support of applications that provide remote power over balanced cabling to terminal equipment,
b) covers the transmission and electrical parameters needed to support remote power over balanced cabling,
c) covers various installation scenarios and how these may impact the capability of balanced cabling to support remote powering,
d) specifies design and configuration of cabling as specified in ISO/IEC 11801-1.
NOTE SELV requirements specify a maximum voltage of 60 V DC and LPS is understood in the applications referenced to be up to 100 W supplied within 4-pair cabling.
This document includes a mathematical model to predict the behaviour of different bundle sizes, various cabling constructions, and installation conditions for different current capacities.
Safety (e.g. electrical safety and protection and fire) and electromagnetic compatibility (EMC) requirements are outside the scope of this document, and are covered by other standards and regulations. However, information given by this document can be of assistance.
Originated as AS/NZS ISO/IEC 29125:2012.
Revised and redesignated as SA TS 29125:2019.
Reissued incorporating Amendment No 1 (July 2021).
