The NetSure™ 211 is especially designed for all types of access applications in both fixed and wireless access networks, offering unmatched site installation flexibility. Environmental Endurance Configurability for Space and Energy Efficiency Application Great output power at high temperatures NetSure™ 211 rectifiers deliver high output power in relation to ambient temperature conditions (see diagram 1), making them especially suitable for high-temperature environments.
The NetSure™ 211’s extensive battery management capabilities, easy configuration and maintenance are all backed by the resources and quality reputation of a worldwide service organization. Basic Configurations Two core configurations define the combination of rectifier and distribution shelves and determine the ultimate capacity of the system. Internal Distribution up to 3kW Our most compact system measures 1RU high with distribution capability and rectifiers in the same shelf.
Rectifier Shelves The rectifier shelves integrated into the NetSure™ 211 system are either 1.75" (1RU) or 3.5" (2RU) high and available in 19" and 23" widths. These shelves provide front to back ventilation and can be mounted directly above or below other electronic equipment, maximizing revenue-generating space. Each unit will operate from 120/208/240VAC and is equipped to accommodate plug-in AC connections or open wire line cords.
Distribution Output distribution for the NetSure™ 211 is available in four different forms. Internal distribution is attained through GMT fuses or circuit breakers. Internal distribution options include: (10) GMT fuses (1RU); or 13 GMT fuses composed of a combination of 15A positions and 10Amp positions; or (4) load circuit breakers (0 to 100A) and (5) 10A GMT fuses; or (2) load circuit breakers (0 to 100A) and (2) battery disconnect circuit breakers (0-125A) and (5) 10A GMT positions.
