Product Overview
The Huawei R4850G2 (R4850G series) is digital high-frequency hot-swap rectifier specially engineered for Huawei ETP48200 embedded telecom power cabinet. Rated max 56.1A/3000W@53.5VDC, it converts wide-range single-phase 85~300VAC mains into adjustable 42~58VDC standard telecom voltage. Equipped mature active PFC and soft-switch technology, peak conversion efficiency ≥96%, full-load power factor ≥0.99 and low THD≤5%. Standard drawer hot-plug design allows online replacement without shutting down the whole power system; built-in CAN bus connects with cabinet monitoring unit for remote parameter setup and real fault reporting, widely used for FTTx OLT, DSLAM and indoor/outdoor 4G/5G micro base station power configuration and old cabinet renovation projects.
