4 FAQs about 380V System Integration of Communication Power Supply Cabinets for Island Use

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.).

Why should you use 380 VDC?

Using 380 Vdc reduces the normal operating current by a factor of 7 compared to 48 Vdc – so reducing copper use per kW of load – and greatly increases the flexibility of site designs, with batteries no longer required to be close to the power converters, and the load able to be located 100s of meters away from the power system.

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.

Why should you choose Eltek 380 VDC systems?

Eltek's 380 Vdc systems provide operators with the ability to solve the combined challenges of ever greater power density, varying load types, and increased site flexibility without compromising on performance, cost, or serviceability.
