Q: What are the extreme environmental ratings and surge/lightning protection tolerances?

The ETP4830-A1 functions continuously across a wide operating temperature span of -40°C to +65°C (with thermal derating applied above +45°C), and supports 5% to 95% relative humidity (non-condensing). It is operational up to 4,000 meters altitude (derating applies above 2,000m). For electrical protection, the AC input is equipped with surge suppression rated at 2kV differential mode and 4kV common mode conforming to IEC 61000-4-5 standards. The unit adheres to Class B electromagnetic compatibility (EMC) standards, allowing safe coexistence in dense outdoor and industrial enclosures.

Question 1

What are the core electrical performance and energy efficiency specifications of the Huawei ETP4830-A1?

Accepted Answer

The Huawei ETP4830-A1 provides a maximum continuous DC output capacity of 30A at nominal -53.5V DC (adjustable between -42V DC and -58V DC) utilizing two 15A rectifier modules. It accepts a wide AC phase input voltage ranging from 85V AC to 300V AC (rated 220V/240V AC). Full 30A output is delivered at 176V~300V AC, with linear derating occurring between 85V and 175V AC. When outfitted with R4815G1 rectifiers, peak conversion efficiency exceeds 96%, with a power factor (PF) ≥ 0.99 and total harmonic distortion (THD) ≤ 5%, ensuring clean, ripple-free power to mission-critical telecommunications equipment.

Question 2

Which rectifier modules are supported, and what internal communication bus is used?

Accepted Answer

The ETP4830-A1 is natively engineered to support Huawei's R4815 series rectifiers, specifically the R4815N1 (standard efficiency ≥ 94%) and R4815G1 (ultra-high efficiency ≥ 96%). While physically interchangeable, deploying matching models is recommended for optimal active load-sharing (current sharing imbalance < ±5%). Rectifiers communicate with the integrated monitoring unit (SMU01C/SMU01B) across an internal high-speed CAN bus, facilitating automated module registration, parameter assignment, and dynamic voltage regulation without manual DIP configuration.
