Product Overview
The Huawei R4850G2 & R4850G6 are original digital high-frequency hot-swap rectifier modules specially engineered for Huawei ETP48100-B1 19-inch embedded telecom power system, supporting single/dual module configuration(max 100A full system output). Rated 3000W/56.1A@default53.5VDC, the modules convert wide-range 85~300VAC single-phase mains into adjustable 42~58VDC standard telecom voltage. Adopts mature soft-switch + full digital PFC control technology, full-load PF≥0.99 and peak conversion efficiency above 96%. Standard drawer hot-plug design enables live module replacement without shutting down the whole ETP48100-B1 cabinet; built-in CAN bus realizes real-time data interaction with cabinet monitoring unit for remote parameter setup and fault alert, widely used in FTTx OLT cabinet, indoor 4G/5G micro base station and old ETP48100-B1 power cabinet renovation & spare replacement projects。
Key Features
Ultra-wide AC input:85~300VAC(45~65Hz, dual 110/220V nominal specification), fit unstable civil grid and diesel generator power supply
Adjustable DC output:42~58VDC(default53.5VDC), max56.1A constant power, automatic power derating below 176VAC input
Active full-range PFC design, full-load PF≥0.99, input THD≤5%, effectively reduce grid harmonic loss and long-term operating cost
Complete front pull-out hot-swap construction, plug & play without system power-off for rapid field maintenance
Intelligent thermostatic variable speed fan, auto adjust rotating speed by internal temperature to cut running noise and extend service life
Full multi-layer safety protection:OVP/UVP/OCP/SCP/OTP + AC input lightning surge protection for sealed indoor/outdoor cabinet
CAN bus communication interface, seamless linkage with ETP48100-B1 monitor for remote voltage/current setting & fault upload
Pass CE, TUV, UL, FCC, RoHS certifications, stable -40℃~+75℃ operation, full-power output up to 4000m altitude
