Eltek Greens Up WiMax
RICHARDSON, Texas -- Eltek Valere today announced a family of high-efficiency (HE) AC-to-DC power systems for cellular and WiMAX telecom networks that can reduce power consumption, greenhouse gas emissions and electricity-related operating expenses.
Available in 150-, 300-, 600- and 1200-amp versions, the new Flatpack2 Power Systems are available for all size wireless network locations from base stations to central wireless switching offices. The products will debut at CTIA Wireless 2008 (April 1-3 in Las Vegas) in the Eltek Valere booth (#5927). Also at its booth, the company will leverage a unique count up timer to demonstrate how much energy the wireless industry can save during the show through the use of HE power systems.
The US wireless industry consumes more than 5 billion kWh annually, resulting in the release of nearly 4 million tons of CO2 greenhouse gasses into the atmosphere. Up to 70% of a carrier’s power bill goes to power network equipment, and an often-overlooked contributor to waste energy is the AC-to-DC power system.
Typical DC power systems waste between 8% and 15% of the total energy in the network due to low conversion efficiency, contributing to more than 750 million kWh and 600 thousand tons of unnecessary waste each year.
Flatpack2 Power Systems are based on Eltek Valere's new Flatpack2 HE rectifier, a 2,000-watt, -48 volt rectifier that offers 96% power conversion efficiency.
At that level, the rectifier has the potential to reduce power loss from 1,500 kWh per year to 750 kWh. Given that a typical base station requires 5,000 kWh to operate and that there are roughly 200,000 base stations in the U.S., the power savings are substantial.
“The Flatpack2 is a great piece of power engineering – giving wireless carriers everything they need in a system from economical operation to fast and flexible load connections,” said Greg Fasullo, Eltek Valere Chief Marketing Officer. “At 96% efficiency, this system sets a new industry standard - one that I hope competitors follow so that the true environmental benefits will be widespread.”
