RackShield

19 inch rack mountable user configurable surge protection

The Rackshield surge protection
solution provides vital protection for up
to 12 ports in a 19” rack format. Modules

slide into RackSheild providing customer
configurable communication protection
for telephone lines, networks, cable/digital
Satellite and DDS applications.

Slide in modules allow the RackShield
to be configured to the requirements
of your business and can be removed,
reorganised or replaced by the end user at
any time. Each RackShield unit can house 12
RackShield modules and any combination
of these modules can be installed in any
given device. This unique user configurable
system allows the RackShield to provide
flexible upgradeable surge protection that
can easily be adapted to suit your changing
requirements.

Advanced solid state surge protection
technology is employed in the modules and

each one is able to safely dissipate surge
currents up to 1kA and will automatically reset
in readiness for the next surge or transient
overvoltage. With 4 modules to choose
from, RackShield can protect against surges
conducted through a wide range of data and
communications lines. Each module slides
in and locks securely into the RackShield
enclosure earthing itself automatically and
can be installed or removed without the use
of tools.

The 19” rack mountable enclosure of
the RackShield allows it to be conveniently
mounted alongside the equipment it is
protecting, fitting neatly into any standard
19” rack or cabinet. Occupying only 1U of
rack space, each RackShield provides surge
protection for up to 12 communications or
data ports making it ideal for surge protection
in IT and telecommunications distribution
environments.

Reversible brackets allow the RackShield
to be wall mounted for locations where a
19” rack or cabinet is not available such as
a small office or home office environment or
near a home entertainment system.

A 10 Year ‘No Fuss’ warranty comes as
standard with the RackShield as with all
MTL Surge Technologies products so in the
unlikely event your RackShield fails we will
replace it.
