300A Embedded DC Power System
,96.2% Rectifier Peak Efficiency Telecom DC Power System
,Modular Hot Swap Embedded DC Power System
The NetSure 731 A61-S3 is a mature subrack-type embedded DC power system developed by Vertiv (E merso n), widely used for various telecom equipment. It adopts a 200–250V AC input and provides a stable −48V single DC output with a maximum current of 300A. Equipped with six R48-3000A3 / R48-3000e3 rectifier modules and an M530S controller, the rectifier achieves a peak efficiency of 96.2%. This system applies a modular hot-swap design, intelligent fan speed regulation, and full-range lightning protection. Featuring a standard subrack structure, reliable performance, and easy maintenance, it is an ideal power solution for indoor telecom machine rooms, communication base stations, and FTTX network projects.
