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.

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, multiplex-
ers, LTE, WiMAX, microwave and PBX.
