Environmental Engineering (EE); Power supply interface at the input to telecommunications and datacom (ICT) equipment; Part 3: Operated by rectified current source, alternating current source or direct current source up to 400 V; Sub-part 1: Direct current source up to 400 V

Scope

The present document contains requirements for: • the output performance of the power equipment at the interface A3; • the input of the telecommunications and datacom (ICT) equipment connected to interface A3. The voltage at interface A3 defined in the present document is DC voltage between 260 V and 400 V. The DC power can be supplied by the battery backup of a DC power system. The present document aims at providing compatibility between the power supply equipment and both the telecommunications and datacom (ICT) equipment, and the different load units connected to the same interface A3 (e.g. control/monitoring, cooling system, etc.).
