731 Series

The NetSureTM 731 series by Vertiv is designed to meet the demands of shared BTS sites for multiple tenants. The system lets up to four users do their own calculations for power consumption and manage their own power supply and distribution. The embedded 19-inch system is configured with Vertiv’s new generation rectifier, which has an ultra-high power density of 50A. The maximum system capacity is 600 A, and the system efficiency is above 96%, which meets the construction needs of energy conservation and emission reduction for modern mobile communication. This high-efficiency sub-rack power system comprises three models: NetSureTM 731 A61-S1, NetSureTM 731 AA1-S1, and NetSureTM 731 AA1-S2.
