Eltek ASA today announced the launch of its new Chameleon family of DC power systems, designed to support the new generation of small cell wireless telecom base stations. Telecom carriers will install millions of small cells during the coming years to meet the exponential growth in demand for mobile data capacity in high-density and rural areas. In addition, these low-cost base stations can help to extend wireless service in remote areas. Eltek’s Chameleon rectifiers, developed specifically for the small cell revolution, are low cost, provide quick, easy plug-and-play installation, have a small footprint and a discreet exterior that permits mounting on existing poles or buildings, and blends well in a city environment.
The first product to be launched is the Chameleon 48/650, which is a 48V, 650W stand-alone rectifier with an ac-dc conversion efficiency of 95.5 percent. The highly reliable rectifier is targeted for lamppost applications thanks to its compact 321 mm x 106 mm x 96 mm IP65-rated housing. The small size of the Chameleon 48/650 contrasts with current small cell dc power systems that fit in standard telecom racks, meaning that carriers have to find a place to install a cabinet near the small cell.
“We have developed a high-efficiency power solution dedicated to small cell applications with performance that stands out, and a look that blends in,” said Morten Schøyen, chief marketing officer at Eltek. “Eltek is making a serious effort to address challenges from purchasing, logistics, installation and operations to minimize the total cost of ownership for operators rolling out 4G/LTE networks.”
The Chameleon 48/650 is offered with optional 20 ms or 200 ms hold-up time, to balance output availability and cost against electricity grid stability. These hold-up times are sufficient for the majority of the blackouts in modern electricity grids. The Chameleon 48/650 is convection cooled and the heat sink is an integral part of the protective IP65 housing.
The Chameleon 48/650 is now available for trials and will be generally available in June 2014 via Eltek’s direct sales force. A higher-power model with battery backup is planned for launch in the fourth quarter of 2014.
