NetSure 501 is the new more compact, and yet more flexible,
Cost and space effective system
configurations thanks to smart and
flexible Multi Function Unit, MFU.
(The MFU houses the controller,
DC and Battery breakers, shunts,
alarm boards and optionally disconnection of loads and/or batteries.
DC power system from Emerson. It is especially developed for
Wide AC input window with high
rectifier DC output.
possibility to very space effectively house both batteries and DC
AC current input limitation possible
on rectifiers. This function enables the
user to employ 10A AC breakers, or
smaller, if desired.
Based upon factory pretested units, subrack and complete
the needs of typical telecom applications in the range between
1.7-20.4 kW.
The packaging of the NetSure 501 system configurations gives the
power system in 400 mm deep configurations.
configurations, new customer configurations and adaptations can
quickly, easily and cost effectively be created with NetSure 501,
and you can trust that the telecom norms and standards specified
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 finding a suitable location for an
application 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.
