What this product is
What this product is
The Huawei ETP4830-A1 is an all-in-one 1U rack-mount subrack power unit that incorporates AC input terminals, two hot-swappable rectifier bays, battery and load DC distribution, and an embedded SMU01C monitoring unit inside a depth of only 255mm.
What problem it solves
Eliminates power infrastructure bottlenecks in space-critical installations (such as street outdoor cabinets and mini-shelters) while counteracting unstable grid conditions and providing remote out-of-band monitoring with automated battery preservation.
Who and where it is for
Ideal for 4G/5G micro base stations, optical access nodes (FTTx OLT/ONU racks), edge transmission networking sites, smart grid SCADA substations, and enterprise ICT branch cabinets.
Core advantages
- Ultra-compact 1U profile for standard 19-inch and 21-inch rack mounting, optimizing interior equipment space
- Wide AC input range of 85V AC to 300V AC with integrated surge protection to mitigate electrical grid fluctuations
- High power efficiency (≥ 96% with R4815G1 rectifiers), substantially reducing heat emission and overall site PUE
- Fully hot-swappable modular design with intelligent battery health management and remote RS485/CAN telemetry
