Q: How are the rectifier slot topology, module interoperability, and current-sharing mechanisms architected in the ETP48600-C5A8?

The ETP48600-C5A8 features a high-density dual-tier 12-slot architecture that supports hot-swapping and N+1/N+X redundancy configuration using Huawei R4850G, R4850G2, and R4850N 50A rectifier modules. It integrates autonomous digital active current sharing across all rectifiers, achieving an imbalance deviation of less than ±3%. Managed by the flagship SMU02C monitoring controller via an internal CAN bus, the subrack supports mixed deployments of varying module revisions with automated load balancing. It natively exports telemetry and controls to carrier-grade OSS/NetEco systems via SNMPv3, Modbus, and HTTPS.

Q: What are the environmental resilience ratings, surge suppression, and LVD battery protection schemes of the ETP48600-C5A8?

Rated at IP20, the ETP48600-C5A8 operates reliably across an ambient range of -40°C to +65°C, with rectifiers utilizing intelligent variable-speed forced-air cooling. The power distribution segment incorporates high-conductivity solid copper busbars, integrated Class C/D AC surge arresters (20kA/40kA, 8/20μs), and comprehensive DC surge suppression. Battery protection employs a dual Low Voltage Disconnect system (BLVD for battery disconnect and LLVD for non-critical load shedding) via high-current magnetic latching contactors controlled by the SMU02C, safeguarding external VRLA or LiFePO4 batteries against deep discharge.

Question 1

What are the core electrical output specs and efficiency benchmarks of the Huawei ETP48600-C5A8 subrack?

Accepted Answer

The Huawei ETP48600-C5A8 (SKU: HW-SYS-ETP48600-C5A8) is a standard 19-inch rack-mount telecom DC power subrack with a nominal output of -48VDC (adjustable range: -42VDC to -58VDC). When fully loaded with 12x Huawei R4850G high-efficiency rectifier modules, it delivers a total maximum output of 600A (up to 28.8kW). The system supports a 3-phase 5-wire (380V/220VAC) grid input with an ultra-wide operating range of 85VAC to 300VAC (full power delivered at 176~290VAC). Leveraging R4850G rectifiers, peak conversion efficiency exceeds 96.2%, maintaining a power factor (PF) ≥ 0.99 and THD < 5%, significantly driving down PUE and thermal losses in data centers and telecom core switching sites.
