Scalable DC power system

The Eltek acalable DC power system offers an array of configurable components that come together to produce large-scale, high-power solutions—up to half a million watts!
Overview

Scalable DC power system

Eltek’s scalable line of power solutions is comprised of configurable components designed to meet the needs of Central Offices and other high-power DC applications.A variety of rectifier bays provides 48V DC output ranging from 3000A to 20,000A (if cabled).

Distribution options offer everything from bulk output to circuit breakers, fuses, and even overhead bus arrangements with shunts.
