Vertiv/Emerson -48V Integrated DC Power System High Efficiency 96%
Netsure 531A41 For Telecom Power Supply
The Netsure™ 531 series from Vertiv is a fully-integrated DC power
system consisting of a rectififier and controller that provides
maximum eơiciency for mobile communication applications such as LTE
and FTTx deployments or macro stations. It is designed to meet the
high-eơiciency demands of mobile applications, with high
reliability, high power density, and fully digital features. The
built-in high eơiciency R48-2000e3 rectififier also provides an
ultra high eơiciency of up to 96%, signifificantly improving the
* The installation space and cost can be saved due to its small
size and embedded installation.
* Wide input voltage range(85- 300Vac), strong ability in adapting
* Rectifier working temperature o range: -40 ~+80 C.
* Supports ECO sleep technology, that optimizes system efficiency.
* Efficiency of the rectifier is above 96%, efficiency of the
system is above 95%. Intelligent battery management System, which
prolongs the working life of the battery.
* Provide multiple communication ports such as RS232, Ethernet
port, dry contacts, etc, for flexible networking to achieve remote
