Huawei’s Embedded Power system provides stable -48V DC power for wireless and fixed access networks, transmission networks and enterprise network equipment. It consists of a power distribution unit, rectifiers, and a controller, etc., and can be deployed independently or embedded into other power cabinets.
The capacity of Huawei’s high-efficiency embedded power ranges from 30A to 400A. Every functional unit is designed to a standard size. The systems, whose height ranges from 1U to 9U with standard 19-inch rack or cabinet installation, have a modular design to facilitate installation and expansion. The system encompasses a wide range of AC input voltage, with accurate battery management and remote management functions.
ETP4890-A2 is an AC/DC embedded power system with excellent performance such as high power efficiency, intelligent battery management, remote management, wide range of AC input voltage, etc.
The system can configure 1U 15A/30A high rectifier modules, and provides 90A rated current output.
ETP4890-A2 can be embedded in 19-inch rack or cabinet.
