4 FAQs about 380V Communication Cabinets for Chilean Data Centers

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:

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.

What is a 380 VDC UPS system?

Typical 380 Vdc UPS system configurations are based directly on existing telecom 48 Vdc concepts, which have been applied for decades in highly reliable applications. The following diagrams illustrate how these Topology Classes can be realized with 380 Vdc based power distribution.

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.).
