4 FAQs about Comparison of 380V Maintenance Costs for Network Cabinets

Are 380 VDC systems reliable?

Failed components can be easily replaced on site. Reliability studies and records conducted to date indicate that 380 Vdc systems (much like 48 Vdc systems) exhibit several order higher availability and resiliency than equivalent systems employing ac-UPSs. Reliability and Efficiency improvements have a direct impact on Total Cost of Ownership.

Can 380 VDC power distribution improve site availability?

An attractive alternative to meet the objective of improving efficiency and improving (or maintaining) site availability is the application of 380 Vdc distribution rather than ac voltages in data center power distribution or 48 Vdc in telecom facilities.

When can 380 VDC be used in a data center?

The connection can be accomplished during initial installation, during expansion, or anytime renewable resources are added without impact on ac distribution infrastructure. The application of 380 Vdc to the modern data center has significant implications that will be developed more fully in additional papers as summarized below:

What is a 380 VDC-PDS infrastructure?

Specifically, the Standard defines a nominal 380 Vdc-PDS infrastructure that interconnects sources of power to devices in the data/telecom center that draw the power. Provide for the use of safe power levels, as defined by the 2011 NFPA® National Electric Code® (see Related Documents Section 2.).

To move from 48V to 380V powering

Papers have been written in recent years that discuss the benefits obtained from the utilization of 380V powering in various case studies.
