Q: Which rectifier modules and monitoring units are compatible with ETP48200-C5B6, and how is autonomous current sharing managed?

The subrack natively supports 50A hot-swappable rectifiers including R4850G2 (96% high-efficiency) and R4850N6 (94% standard), accommodating N+1 redundancy. Managed by SMU02C or SMU02B controllers, the system utilizes high-speed CAN bus digital communication to enforce autonomous active load balancing with current unbalance under ±5%. It provides SNMPv3/HTTPS telemetry for remote OSS integration and permits live slot expansion without service interruption.

Q: What are the temperature tolerances, surge suppression levels, and dual-LVD battery protection designs of ETP48200-C5B6 for harsh telecom sites?

Designed for demanding deployment, the system operates from -40°C to +65°C utilizing intelligent variable-speed fan cooling. AC inputs integrate Class C 20kA/40kA (8/20μs) surge protection devices (SPD), paired with 10kA/20kA DC surge suppression. Battery protection features dual low-voltage disconnects: LLVD sheds non-critical cellular loads to extend critical core uptime, while BLVD isolates batteries (e.g., at 43.2V) to stop permanent cell damage, supporting both VRLA and SmartLi batteries.

Question 1

What are the core electrical specifications, input modes, and conversion efficiencies of the Huawei ETP48200-C5B6 subrack system?

Accepted Answer

The ETP48200-C5B6 is a 5U 19-inch rack-mounted DC power subrack with a total rated capacity of 200A, housing 4 × 50A rectifier slots for up to 12kW output. Nominal DC output is -48V DC, dynamically adjustable from -42V to -58V DC. It supports an ultra-wide AC input range of 85V to 300V AC, compatible with both 220V single-phase and 380V three-phase (3P4W/3P5W) grids. Paired with R4850G2 rectifiers, it delivers peak conversion efficiency >96%, THD <5%, and power factor PF ≥ 0.99, optimizing telecom site PUE.
