EnerSys has introduced the Cordex HP 48V-5.0kW rectifier, a new power component designed to increase capacity in broadband infrastructure. The system is currently in the validation phase following its public demonstration at SCTE TechExpo26.
Why it matters
Broadband operators face pressure to boost network throughput without expanding physical facility footprints. This rectifier addresses that constraint by increasing power density and reducing the heat output of continuous-load systems.
The Cordex HP 48V-5.0kW rectifier reaches 97.1% peak conversion efficiency and delivers 15 kilowatts per rack unit. The design, which has earned CSA/UL and IEC/EN 62368-1 Edition 3 certifications, also includes front-access maintenance features.
The players
EnerSys
A global manufacturer specializing in stored energy solutions, including power systems for telecommunications and industrial applications.
The details
The rectifier functions as part of EnerSys Cordex CXPS direct-current power systems, which convert AC input into stable DC electricity for telecommunications infrastructure. Its architecture utilizes a front-access maintenance design, allowing technicians to service units without rear access clearance. This consolidation of components is expected to enable higher power capacity within existing facility racks by increasing power density.
Timeline
September 29 - October 1, 2026: The rectifier was demonstrated at SCTE TechExpo26 in Atlanta.
The Tech Race
This launch signals a strategic shift in the broadband power market toward maximizing output from legacy footprints. It directly updates the EnerSys Cordex CXPS power system ecosystem to address cooling and space limitations common in dense network facilities.
Broadband operators will first see the technology integrated into new site installations using the CXPS-HX, CXPS-C, and CXPS-W power configurations. The design allows for potential floor space recovery in specific shelter environments, though wider commercial availability is subject to validation.
The takeaway
The race to shrink physical data facility footprints while managing increased heat loads is driving incremental gains in power conversion efficiency. Watch for the forthcoming phased commercial release to confirm if the 15 kilowatts per rack unit density holds up in real-world deployment.
