Vertiv(Emerson) R48-5800A / R48-5800E 5800W 48V Telecom Rectifier | For NetSure 801 Power System

Specifications

Product Overview

The Vertiv R48-5800A/R48-5800E is high-power three-phase digital hot-swap rectifier exclusively designed for Vertiv NetSure 80 series large-capacity embedded power system, widely deployed in central telecom equipment room and medium-sized data center DC power configuration. Rated max 5800W/120A@48VDC, it converts 260~530VAC three-phase industrial alternating current into adjustable 42~58VDC standard telecom voltage(default53.5VDC). Adopts full DSP digital control + soft-switch + full-range active PFC technology, peak conversion efficiency reaches 96.2%, full-load PF≥0.99 and ultra-low THD＜5%. Standard large-size drawer hot-swap structure supports live replacement without cabinet shutdown; built-in CAN bus communication realizes multi-module digital automatic current sharing and real-time data linkage with M830D/M810G monitoring unit of NetSure801 cabinet, ideal for new large-capacity power station construction and old NetSure801 cabinet capacity expansion renovation projects.

Key Features

Ultra-wide three-phase AC input:260~530VAC(45~65Hz, nominal380~480V three-phase industrial grid), stable against grid surge and diesel generator fluctuating voltage

Adjustable DC output:42~58VDC(default53.5V), max120A constant power, intelligent input voltage derating below304VAC to protect module safety

Full-range active PFC, full-load PF≥0.99, peak efficiency up to96.2%, drastically reduce long-term central machine room electricity consumption

Complete hot-swap plug-and-play design, front pull handle for rapid field maintenance without whole system power cut

Intelligent group-controlled variable speed forced air cooling, automatically adjust fan speed based ambient and inner temperature to lower idle noise and extend service life

Full multi-protection: three-phase input OVP/UVP, DC OVP/OCP/SCP/OTP plus AC lightning surge protection, built-in reverse connection prevention circuit

CAN bus digital communication, automatic multi-module current sharing without extra auxiliary circuit, support remote voltage/current setting & fault upload via cabinet monitor

Comply CE & NEBS Level3 certification, full-power output from -40℃~+45℃, power derating over45℃, max2000m full-load altitudeVertiv
