Environmental Engineering (EE); Power supply interface at the input of Information and Communication Technology (ICT) equipment;
Part 3: Up to 400 V Direct Current (DC)
The present document contains requirements and measurements methods for the physical interface "A3" that is situated between the power supply system(s) and the power consuming ICT equipment:
• the nominal voltage at power interface "A3" of ICT equipment defined in the present document is DC voltage up to 400 V;
• the output performance of the power equipment including the cable network at the interface "A3";
• the input of the ICT equipment connected to interface "A3".
The DC power can be supplied by a DC output power system e.g. via on-grid AC rectifiers, from DC/DC converters in solar systems, fuel cells, standby generators including a battery backup.
