Vertiv(Emerson) R48-3000E3 eSure Rectifier | 48V 3000W 62.5A Telecom Power Module

Specifications

Product Overview

The Vertiv R48-3000E3 (Former Emerson eSure series) is high-density digital controlled AC-DC rectifier module designed for global NetSure embedded telecom power cabinets. Rated 3000W/62.5A@48VDC, it converts wide-range single-phase AC into adjustable 42~58VDC standard communication voltage, perfectly hot-plug compatible with all Vertiv NetSure series power shelves without cabinet reconstruction. Adopts DSP full digital control + active PFC circuit, peak conversion efficiency reaches 95.5%, ultra-high power factor ≥0.99, low harmonic THD≤5%. Supports intelligent parallel current sharing and load-adaptive energy-saving sleep mode, widely deployed in indoor/outdoor 4G/5G small cell, FTTx OLT pole cabinet and old telecom power capacity upgrade projects.

Key Features

Ultra-wide AC input:85~290VAC,45~65Hz, stable operation under unstable municipal power and diesel generator supply

Adjustable DC output:42~58VDC(default53.5VDC), max continuous 62.5A, constant power output characteristic

Active PFC design, full-load PF≥0.99, THD≤5%, peak efficiency up to 95.5%, reduce long-term power consumption

Standard drawer hot-swap structure, replace module under live cabinet without system power-off, maintenance within 1 minute

Intelligent variable speed cooling fan, auto adjust rotating speed based inner temperature to cut idle noise and extend lifespan

Built-in CAN bus communication interface, real-time data interaction with cabinet monitor for remote parameter setup & fault alarm

Multi-layer full protection:OVP/UVP/OCP/SCP/OTP + AC input lightning surge protection for harsh outdoor cabinet environment

Full power output below +45℃, gradual power derating above ambient 45℃, stable for high-temp sealed pole cabinet
