The NetSure 531A31-S1 is a highly reliable 3U compact embedded DC power system by Vertiv, supporting 150A to 200A system capacity and fully compatible with high-efficiency R48-2000e3 rectifier modules, engineered for rigorous telecom rooms and edge data centers.
Need to confirm a model, specification, or project configuration? Our team can follow up by email or phone.
Utilizing a standard 19-inch rack 3U height structure, the system integrates AC distribution, DC distribution, rectifier module slots, and an advanced intelligent controller. By housing high-density R48-2000e3 modules, it delivers high-quality -48V stable DC power to meet high power density and space-saving demands.
Effectively resolves space constraints in legacy telecom rooms, low energy efficiency of older power plants, and high maintenance overheads. High-frequency soft-switching tech and intelligent sleep algorithms significantly cut utility bills and thermal losses.
Widely applicable to Fixed Wireless Access (FWA) networks, cellular base stations, Distributed Antenna Systems (DAS), enterprise core switch rooms, and small-to-medium edge data centers.
