The 6 x 1800W power shelf of Cherokee has been selected for the deployment of a major new cellular network in Europe. The systems shelves have been preferred for its ease of integration, simplicity of control locally or over IP and proven outstanding reliability.

In the 24/7 telecom environment, quality and reliability are mission critical. For Cherokee International, this end market includes cellular base stations, broadband switching equipment, radio frequency amplifiers and XDSL access networks. A common thread in all these applications is 100% up-time because service interruptions can cause loss of revenues to the carriers. That’s why telecom customers typically use distributed power architecture schemes, frequently employing N+1 redundancy to ensure system availability.

Most telecom equipment is driven from a 48V DC bus provided by an energy system located at the central office. A 48 DC voltage source feeds the end equipment where a secondary step-down conversion is required to power critical components like microprocessors, I/O and memory. Our latest DC/DC converters, a perfect complement for this type of application, offer high current density in industry standard packages that can be customized for a particular requirement.

As the telecom market continues to evolve, a new market has emerged – a convergence of voice, data and video from one service provider – telecom’s version of the “triple play.” There is a shift in moving telecom equipment away from the central office and closer to the end-user or access network, creating a need for a new architecture (remote power feeding) to power access networks in a cost effective and reliable manner.

Cherokee International has successfully introduced its solution in Europe for a remote power feeding application, representing one of the first installations providing data, voice and video from one carrier to the end-user.
