Product Overview
The Huawei TP48300B is an indoor cabinet-type DC power system that supplies -48 VDC telecommunication equipment in medium-sized equipment rooms and base station shelters. Built from 50 A rectifier modules, the system reaches a maximum output of 300 A, providing a step between embedded systems and the larger 600 A TP48600B plant.
The cabinet integrates power distribution, a PMU monitoring unit, rectifier slots and dedicated battery space, allowing operators to combine rectification, distribution and backup energy in one enclosure. As part of Huawei’s TP48400 series cabinet family, it shares platform components and monitoring architecture with other TP48x00B systems.
For operators and enterprises expanding indoor sites, the TP48300B offers a scalable path: rectifiers can be added as load grows, while the PMU provides remote monitoring of the power system and connected objects. The product page is published on Huawei’s official support portal, and detailed parameters are defined per sub-model configuration.
