Hong Telecom have several partners for telecom power/energy suppling, the biggest one is our friend enterprise: Emerson (Vertiv).
In following text, Hong Telecom will show you one model Embedded High Frequency Switching Power System Netsure 501/701 power cabinet.
Emerson NetSure501 A41 and NetSure701 A41 embedded power systems are highly reliable, fully digital communication power systems that offer high power density and high performance. Developed by Emerson Network Power based on many years of development and network operating experience, these solutions meet the network requirements of 3G, FTTx, data communication equipment,
transmission equipment and access equipment.This system is compatible with multiple types of high frequency switching mode rectifier modules developed by Emerson. Each includes a rectifier redundancy energy saving function that combines HE (high efficiency) and SE (standard efficiency) rectifiers in one system. It has perfect surge protection features on the AC and DC sides and on signal interfaces, making it particularly suitable for supplying power to outdoor BTS cabinets and outdoor equipment rooms.
There are 3 type of slots setting for Netsure 51 or 701:
