Huawei R4830G1 48V 30A 1600W High Efficiency Telecom Rectifier Module

Specifications

Product Overview

The Huawei R4830G1 is compact high-efficiency digital hot-swap rectifier, specially designed to match Huawei ETP series embedded telecom power cabinets including ETP4890-A2 and related models. Rated 1600W/30A@53.5VDC (up to 1740W under full nominal AC input), it converts wide-range 85~300VAC single-phase mains into adjustable 42~58VDC standard telecom voltage. Adopts advanced full digital control and active PFC topology, peak conversion efficiency reaches 96%, full-load PF≥0.99 and ultra-low THD≤3.5%. Standard 1U slim drawer hot-plug design allows online replacement without cabinet power-off; built-in CAN bus communication links with cabinet monitoring unit for remote parameter adjustment and fault alert, widely applied in indoor FTTx OLT, DSLAM and small-capacity 4G/5G micro base station power configuration and old equipment spare replacement projects.
