Benets Cost and space effective system
congurations thanks to smart andexible Multi Function Unit,
MFU.(The MFU houses the controller,DC and Battery breakers,
shunts,alarm boards and optionally discon-nection of loads and/or
batteries.
Wide AC input window with highrectier DC output.
AC current input limitation possibleon rectiers. This function
enables theuser to employ 10A AC breakers, orsmaller, if
desired.
NETSURETM501DC Power System, -48 V DC, 1.7 20.4 kW, 35 420 A
NetSure 501 is the new more compact, and yet more exible,
DC power system from Emerson. It is especially developed for
the needs of typical telecom applications in the range
between
1.7-20.4 kW.
The packaging of the NetSure 501 system congurations gives
the
possibility to very space effectively house both batteries and
DC
power system in 400 mm deep congurations.
Based upon factory pretested units, subrack and complete
congurations, new customer congurations and adaptations can
quickly, easily and cost effectively be created with NetSure
501,
and you can trust that the telecom norms and standards
specied
for the product are always adhered to.
As the business grows, NetSure 501 is easily extended with
additional capacity and can be upgraded with supplementary
features and functions during live operation.
With NetSure 501 the process of nding a suitable location for
anapplication and its power supply is facilitated, thanks to the
wide
tolerance window of NetSure 501 when it e.g. comes to
operating
temperature, AC input window of AC input breaker size.
