Eltek Valere Debuts New DC Power System For Central Offices With Pyramid Bus Structure
Eltek Valere announced the release of its Powerpack Scalable, a new fully integrated dc power system for central offices, mobile telephone switching offices (MTSOs), data centers and other high-capacity computing / networking centers. The new system can scale up to 10,000A and is said to be optimized for facilities where high power needs and easy expandability are important.
The Powerpack Scalable is a brand new system based on Eltek Valere’s three-phase, 48V Powerpack rectifiers. The rectifiers are rated at 200A and offer 93.5% efficient (max.) power conversion with available 208 or 480Vac input options. Using three-phase power, the Powerpack rectifiers are said to provide more reliable and evenly distributed power.
The Powerpack Scalable rectifier bay is a compact and easily upgradeable system that can accommodate up to 15 Powerpack rectifiers and provide up to 3,000A in a single bay. The design of the rectifier bays was also optimized with easy rear access and flexible load distribution to make expanding the number of rectifiers in the bay easy.
For larger power implementations, the Powerpack Scalable plant has a unique pyramid busbar structure that enables multiple rectifier bays to be joined to offer up to 10,000 amps of power for growing telecom or enterprise power applications. The pyramid busbar was developed by Eltek Valere in response to challenges its customers were having with interleaved busbars that required special equipment to expand, making them not easily field upgradeable. With the Eltek Valere XC2100 controller the system can be monitored and configured remotely over an IP network. Each rectifier also has an LCD screen for local configuration and monitoring.
"In order to stay in step with the technological advances in IPTV and other wireless applications, central offices are facing increased pressure to quickly and efficiently add more power," said Allen Pitts, Eltek Valere President for the Americas. "The Powerpack Scalable plant provides central offices a simple solution, as more rectifier bays can be added at any time using this pyramid structure."
