Product Overview
The Huawei ETP4830-A1 is a compact 1U embedded power system for access networks, transmission equipment and enterprise communication rooms. With two 1U 15 A high-efficiency rectifier modules it provides a 30 A rated output (2 kW maximum) in the smallest possible footprint, embedding directly into 19-inch or 21-inch racks and cabinets.
The wide 85-300 VAC input range tolerates unstable grids common in remote sites, while the output is adjustable from 42 to 58 VDC with a 53.5 VDC default for -48 V equipment. Both rectifiers and the SMU01A/B/C monitoring unit are hot-swappable, supporting tool-free maintenance without interrupting the load bus.
Natural cooling keeps the system silent and maintenance-free, and front inlet/outlet cabling with front maintenance simplifies installation in shallow cabinets. Intelligent battery management, rectifier dormancy and environmental monitoring via dry contact, serial or Ethernet interfaces complete a feature set aimed at unattended sites where every watt and every RU counts.
