NetSure™ 7100 Standard Series is designed for wireless and fixed network access applications.
This 48 VDC power solution, features the advanced NetSure Control Unit (NCU), up to (9) 3500 W high-efficiency eSure™ rectifiers and a multi-function battery and distribution connection unit.
The 17.5 kW subrack comes in a 5U high integrated power shelf and the 31.5 kW subrack in a 6U high integrated power shelf, both supporting 19" rack mounting. The distribution section supports up to (29) load circuit breakers and up to (6) battery circuit breakers. The distribution circuit breakers can be divided into two priority load disconnect levels via dedicated LVD contactors. Prioritized load disconnect can resultin significant savings on the backup battery investment. Standard remote monitoring and software upgrades are available through web
browsers, TCP/IP and SNMP. Remote access via RS485 (Modbus) as well as GPRS/3G/4G modems are available as options.
NetSure DC Power systems offer extremely low failure rates, as well as low total cost of ownership. The 3500 W eSure rectifier delivers peak system efficiency above 96%. Maximum value is achieved by an advanced energy optimization function known as ECO mode, enabling significant energy savings even at low loads.
Application
The NetSure 7100 Standard Series DC power system is designed for deployment
in telecom access network applications requiring a reliable and high power density
supply up to 31.5 kW at 48 VDC. The system is available as a subrack for integration
in an outdoor enclosure or existing cabinet, mounted on top of a battery rack or
integrated in a cabinet.
KEY FEATURES
High Efficiency - 96.3% efficient eSure rectifiers ensure optimized total cost of ownership
