Description
The NetSure™ 211 DC Power Solution is a flexible system capable of providing DC power through the use of 500W or 1000W rectifiers and a variety of output distribution options. The system is available in an integrated distribution configuration. The NetSure™ 211 is available in both 19" and 23" 1RU & 2RU rack-mount configurations, suited for up to 6kW power requirements in the most harsh environments. The system is supported by a single SCU+ or ACU+ controller (ACU+ for 2RU systems only) that provides all control and operational conditions, as well as historical site data and external signal conditioning and monitoring. Each rectifier shelf includes a slot for the controller and space for the rectifiers. Distribution is provided by breakers or fuses located in the power shelf.
Distribution options include load low-voltage disconnect (LLVD), battery low-voltage disconnect (BLVD), or no low-voltage disconnect. Plug-in rectifiers, AC connectivity and DC load outputs enhance the overall flexibility of the system by minimizing installation and start-up time. This dynamic system also offers alternative AC input configurations, relay rack configurations, battery tray options, battery box options and pre-configured output load kits.
The NetSure™ 211 is designed for up to 4kW loads (19") or 6kW loads (23"). This cost-effective solution is NEBS Level 3 compliant and UL Listed. Rated for continuous operation from -40°C to +75°C, this system is designed for the harsh outside plant environment, as well as customer premise FTTx, wireless back-haul, microwave, and DLC applications.
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
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. In a system with rectifiers operating at 65°C, the output is still 60% of full power.
Extremely wide AC voltage range window
The AC voltage input range vs. rectifier output is another extraordinary feature of this small system. The 1000W rectifier will deliver full power from 176 VAC to 300 VAC. From 85 VAC to 176 VAC the power level is derated (see diagram 2). The 500W rectifier will deliver full power from 104 VAC to 300 VAC.
Configurability for Space and Energy Efficiency
NetSure™ 211 comes in many different shapes
This highly flexible DC power system, featuring efficiency levels greater than 92%, is available in 1RU or 2RU integrated distribution shelves. These alternatives are optimal for rack-mounting in any building, shelter or cabinet installation.
NetSure™ 211 is easily integrated into any Emerson outdoor enclosure when a pre-manufactured space-efficient outdoor solution is needed. The system can also be shipped loose or mounted in a relay rack with battery trays.
Application
The NetSure™ 211 System is designed for deployment in central office, POP sites, co-location sites, customer premises, outdoor cabinets, CEVs, vaults or portable shelters. Specific applications include: DLC, xDSL, DSLAM, FTTx electronics, broadband communications, multiplexers, LTE, WiMAX, microwave and PBX.
