4 FAQs about 380V Network Cabinets for Microgrids in Five Central Asian Countries

Do 380 VDC distribution topologies meet BICSI standards?

The BICSI Standard goes on in §9.3.13.2 to state: “Direct current power systems that serve critical loads have the same availability requirements as ac power systems with additional consideration given for personal safety.” 380 Vdc distribution topologies fully meet the objective of this standard.

Can 380 VDC power be used in a data center?

While there are others, two noteable complementary standards guide the application of 380 Vdc power to the data center. One is available in ANSI/BICSI 002-2011. A second was developed by, and available through, the EMerge Alliance Data/Telecom Center Standard Version 1.0. Summaries of these standards are included as appendices to this paper.

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-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.).
