ITU-T L.1200
Direct current power feeding interface up to 400 V at the input to telecommunication and ICT equipment - Study Group 5
Year: 2012
Abstract: This Recommendation is aimed at providing compatibility between the power feeding system and ICT equipment installed at telecommunication centres, data centres and customer premises. This Recommendation deals with the requirements for an up to 400 VDC interface between power feeding system and ICT equipment.
This Recommendation covers the following main items:
• The identification of a power feeding system with the same characteristics for all ICT equipment defined in any location where an up to 400 VDC interface is used, e.g., telecommunication centres, radio base stations, data centres and customer premises.
• The 'up to 400 VDC' voltage range in normal and abnormal service conditions at the interface defined in this Recommendation.
• Behaviour during voltage variation, dips, short interruptions, transients, inrush current, grounding, etc.
The general requirements for safety and earthing and bonding are out of the scope of this Recommendation unless specific requirements are not defined in current standards.
