READING, PA — EnerSys (NYSE: ENS) is preparing to introduce a higher-efficiency power conversion system for broadband and communications networks, targeting electricity consumption and equipment-space constraints as operators expand capacity within existing facilities.
The Reading-based industrial energy company has developed the Cordex HP 48V-5.0kW rectifier for integration into its Cordex CXPS direct-current power systems, which supply electricity to broadband headends, network hubs and central offices.
The rectifier delivers up to 97.1% peak conversion efficiency, a maximum output of 5 kilowatts and power density of 15 kilowatts per rack unit, according to EnerSys.
Those specifications are intended to reduce electricity lost during conversion from alternating current to direct current while increasing the power capacity available within existing equipment racks.
The technology addresses a recurring infrastructure challenge for broadband operators: increasing network capacity without proportionate expansion of equipment rooms, shelters and electrical systems.
Because communications facilities operate continuously, improvements in power conversion efficiency can reduce both electricity consumption and the heat generated by electrical equipment.
EnerSys plans to integrate the rectifier into its Cordex CXPS-HX, CXPS-C and CXPS-W power system configurations.
The CXPS-HX and CXPS-W systems also feature front-access maintenance designs, eliminating the rear service clearance required by some conventional equipment arrangements.
In a representative 10-foot-by-8-foot telecommunications shelter containing one power system and two battery racks, EnerSys estimates that a front-access configuration could recover as much as 17.5% of total floor space.
The additional space could accommodate other equipment or provide greater flexibility when operators upgrade existing facilities.
The rectifier also supports universal alternating-current input, reducing the need for separate equipment variants designed for different electrical supply configurations.
That capability is intended to simplify equipment procurement, inventory management and replacement-parts requirements across network deployments.
“Broadband operators are being asked to add network capacity while working within existing energy, rack-space and facility constraints,” said John Hewitt, vice president of communications for the Americas at EnerSys.
“That is why we see efficiency increasingly as a system-level issue, not simply a rectifier specification,” Hewitt said.
The rectifier has received certification under CSA/UL 62368-1, Edition 3, for the United States and Canada, along with IEC/EN 62368-1, Edition 3, for markets in Europe, Asia Pacific, the Middle East and Africa.
EnerSys is continuing system-level validation ahead of a phased commercial introduction.
Initial availability is planned for approved new installations, followed by additional Cordex CXPS configurations and selected existing installations as validation, certification and commercial-readiness requirements are completed.
The company also scheduled a demonstration of the rectifier integrated into a front-access Cordex CXPS-HX power system at SCTE TechExpo26, held September 29 through October 1 at the Georgia World Congress Center in Atlanta.
The demonstration focused on conversion efficiency, power density and equipment maintenance access in communications network installations.
