The Central Energy System is a solution to feed remote locations from a power source located in a central location (hub) over existing or new copper networks installed with the regulatory constraints applicable to telecom networks. The design based on the IEC (EN/UL) 60950/21 features the installation of 32 insulated and independent DC/DC  converters. The system can be connected to 48V or 60V redundant sources to provide superior availability of the services at remote locations.
The standard supports two modes for power transmission: RFT-C and RFT-V. The CP053/xxL350 is designed around the RFT-C mode to offer full safety in any conditions of operation and distance from the central office equipment. Furthermore, the RFT-C mode is easy to dimension and implement. The current limitation avoids potential overheating of cables.
The remote feeding solution from Alpha Innovations results from years of experience and work with leading network operators. Beyond the requirements of the standard, each line is protected to bring the maximum current capability well below the safety limits in case of short circuits line to line or line to ground. Feeding power at 350V in normal operation, the voltage of each line will go independently below 50V if the line is opened.
Remote feeding solution offers numerous advantages versus traditional AC/DC conversion for remote locations. If the most obvious advantage is to support high availability of signals while avoiding the multiplication of batteries in the field, it also eases and supports faster network deployment. In many applications it finally brings significant measurable cost savings compared to traditional solutions.
The system is designed primarily to be installed in central office equipment, but can also be installed as one component of a delocalized power hub serving multiple small remote nodes. Designed and manufactured with state-of-the-art technologies and processes, electronic cards are hot pluggable and very easy to install and replace without any specific tools or special care.
