What this product is
What this product is
The system features an integrated 9U chassis layout comprising high-capacity AC/DC distribution circuit breakers at the upper tier, an SMU02C controller with UIM interface cards in the mid-tier, and an 8-slot dual-row hot-swap rectifier bay at the bottom.
What problem it solves
Resolves severe vertical space constraints in modern telecom cabinets, eliminates single-point DC feed failures, prevents premature lead-acid/lithium battery depletion, and minimizes site energy loss via 96%+ conversion efficiency.
Who and where it is for
Engineered for 5G macro sites, core metro aggregation, and enterprise data centers, the Huawei ETP48400-C4A1 subrack accommodates up to eight R4850G2/R4850N1 50A rectifiers. It integrates multi-channel load distribution, dual-level low voltage disconnection (LLVD/BLVD), and SNMP-enabled remote supervision.
Core advantages
- Ultra-Dense 400A Output: Compact 9U chassis delivers up to 400A nominal capacity to satisfy multi-carrier wireless and transport nodes
- Exceptional Power Efficiency: Optimized for R4850G2 modules with peak energy efficiency exceeding 96%, slashing operating OPEX
- Comprehensive Battery Protection: Programmable LLVD and BLVD contactor schemes prioritize critical loads and prevent battery over-discharge
- Carrier-Grade Fleet Management: Driven by SMU02C controller supporting SNMPv3, WebUI, CAN bus, and multi-channel environmental telemetry
