What this product is
What this product is
The Huawei ETP48200-C5B7002 is engineered for telecom radio access networks, transmission nodes, enterprise communication networks, and small-to-medium central offices. Integrated within a standard 19-inch 5U subrack, it houses AC input terminals, rectifier slots, DC distribution breakers, the SMU02C monitoring controller, and dual low-voltage disconnection contactors (LLVD and BLVD) to secure uninterrupted -48VDC power supply.
What problem it solves
Resolves erratic grid instabilities in remote stations through ultra-wide input voltage tolerance, minimizes rack footprint via high power density, and prevents irreversible battery destruction during prolonged outages using precision dual-tier disconnection.
Who and where it is for
4G/5G macro cell stations, transmission repeater nodes, FTTx central offices, industrial communication racks, and enterprise core IT/networking rooms.
Core advantages
- Ultra-wide 85VAC to 300VAC operational input range, sustaining up to 415VAC phase voltage without damage
- High-efficiency rectifier architecture achieving ≥96.0% peak conversion, minimizing site thermal emission
- Fully hot-swappable rectifiers and central monitoring controller for zero-downtime maintenance and scaling
- Intelligent multi-stage battery management: thermal compensation, auto boost/float switching, and programmable LLVD/BLVD
- Extensive south/northbound interfaces (Fast Ethernet, RS485, CAN) natively supporting SNMP v2/v3 and Huawei NetEco
