The Vertiv R48-3000e3 is an industrial high-efficiency switch-mode telecommunication rectifier module designed to convert standard AC input into regulated -48V DC power with up to 3000W output for telecom and enterprise mission-critical DC systems.
Need to confirm a model, specification, or project configuration? Our team can follow up by email or phone.
The R48-3000e3 utilizes modern digital signal processor (DSP) control and resonant conversion topology to transform single-phase AC input (85V to 300V) into highly stable -48V DC output. It incorporates active Power Factor Correction (PFC), integrated variable-speed cooling fans, CAN bus communications, and built-in protection against overvoltage, overtemperature, and load short-circuits.
It addresses energy wastage, thermal dissipation stress, and unexpected site outages in demanding grid environments by maximizing conversion efficiency up to 96.2% and providing full hot-swap redundancy for continuous 24/7 telecommunication operations.
Compatible with Vertiv NetSure 500, 700, and 800 series DC power systems, outdoor telecom enclosures, wireless base station power plants, and edge computing DC architectures.
