Environmental Engineering (EE); Power supply interface at the input of Information and Communication Technology (ICT) equipment; Part 2: -48 V Direct Current (DC)
The present document contains requirements and measurements methods for the physical interface "A" that is situated
between the power supply system(s) and the power consuming ICT equipment.
The nominal voltage at power interface "A" of ICT equipment defined in the present document is DC voltage -48 V.
The DC power can be supplied by a DC output power system (e.g. based on AC rectifiers on grid or DC/DC converters on
solar system, fuel cell, DC engine or fuel cell generator) and also directly supplied by a battery backup in this DC power
system. The purpose of the present document is to be able to use a power supply system with the same characteristics
for all ICT equipment defined in the area of application:
