scope:

The present document introduces a series of standards sub-parts specifying Power Supply Interface A3 at the input to telecommunications and datacom (ICT) equipment:

Part 3-1: "Operated by rectified current source, alternating current source or direct current source up to 400 V; Sub-part 1: Direct Current source up to 400V";

Part 3-2: "Operated by rectified current source, alternating current source or direct current source up to 400 V; Sub-part 2: Alternating up to 400 V solution".

Part 3-3: "Operated by rectified current source, alternating current source or direct current source up to 400 V; Sub-part 3: Rectified current up to 400 V solution".

The power can be supplied at the interface by a single source or a multi-source system that may include batteries or back-up generators or renewable energy sources.

The sub-part document aims at providing compatibility between the power supply equipment and both the telecom/datacom (ICT) equipment. The same interface A3 can be used for other load units connected (e.g. control/monitoring, cooling system, etc.).

The requirements at interface A3 defined in the sub-parts 1 to 3 apply to:

• the output of the power supply equipment or power supply installation for powering telecommunications and datacom (ICT) equipment;

• the power supply input of telecommunications and datacom (ICT) equipment;

• other equipment power supply input compatible with this interface.

The purpose of the present document is:

• to identify a power supply system with the same characteristics for all telecommunications and datacom (ICT) equipment defined in the area of application. The area of application may be telecom center or datacenter or customer premises (e.g. business buildings);

• to facilitate the standardization of power supply systems for telecommunications and datacom (ICT) equipment;

• to facilitate the installation, operation and maintenance in the same network of equipment and telecommunications and datacom (ICT) equipment or system from different origins;

• to facilitate interworking of different types of loads.

General requirements for safety and EMC are out of the scope of the present document series unless specific requirements are not defined in existing safety or EMC standards.
