IEC 63316:2026 pdf download,Audio/video, information and communication technology equipment – Safety – Power transfer between communication equipment ports using communication wires and cables cabling at non-mains voltage above 60 V DC and ES2/ES3 AC voltage.
IEC 63316:2026 is a safety standard published by the International Electrotechnical Commission, focusing on non‑mains power transfer over communication cables in audio/video, information and communication technology equipment. It addresses circuits operating at >60 V DC or ES2/ES3 AC (as defined in IEC 62368‑1:2023), which pose elevated electric shock and fire risks.
The standard applies to power sourcing equipment (PSE) and powered devices (PD) interconnected via communication wires, including repeaters, amplifiers, optical network units, remote DSLAMs and telecom cabinets. It specifies mandatory safety safeguards, test protocols and compliance criteria to mitigate hazards from such high‑voltage power delivery.
Key requirements cover insulation coordination, overcurrent protection, grounding, isolation and creepage distances, ensuring robust protection under normal and fault conditions. It also defines ES2 (low risk) and ES3 (higher risk) classification rules, with stricter measures for ES3 deployments.
As a complement to IEC 62368‑1, it provides product designers, manufacturers and test labs with a unified framework for safe implementation of remote power‑over‑communication‑cable systems. It is widely used in telecommunications, data networks and industrial communication infrastructure to ensure global consistency in safety evaluation and risk reduction.
