EMP-Protectors USN Series

USN-Series to protect data signals

The USN-series is designed to provide protection against surge and interference voltages as feed-through type mechanical unit for data and control line systems. Depending on the specific application different types are availble. The highly effective multi-stage transient protection design combined with filtering components provides excellent protection against the effects of atmospheric discharges (lightning, electrostatic discharge) or a High Altitude Electro-Magnetic Pulse (HEMP), sometimes also referred to as Nuclear Electro-Magnetic Pulse (NEMP) or simply EMP. Special features of this series of protection circuits include high surge current capability, compact feed-through design and simple installation directly to Faraday cage.

 

The USN-Series will be threat-level tested against EMP according to MIL-STD-188-125, short pulse and intermediate pulse.

 

USN-22001 2 * VDSL / ADSL / ISDN / POTS

Meteolabor® USN-22001 protects two telephone wire pairs
of analog or digital telephone subscriber lines (POTS, ISDN,
DSL, ADSL, VDSL) against the effects of lightning and EMP.
USN-22001 has pluggable WAGO MCS Micro terminal
blocks with locking levers and CAGE CLAMP® contacts. The
wires are easy to install by using the supplied operating tool
or a matching screw driver.
For best protection results a feed-through installation from
an unprotected volume into a shielded and protected room
is recommended.
USN-22001 protector/filter is designed to be used in fixed
installations (buildings, underground shelters etc.) as well as
in portable and mobile systems like containers or shelters
and vehicles, which need to be EMP-tested according to
RS105 of MIL-STD-461F.

USN-40001 10/100 Mbps Ethernet

Meteolabor® USN-40001 combines the protection of two
pieces Meteolabor® USS-2-AQ in one case to provide
excellent protection for two twisted pairs of a 10/100 Mbit/s
Ethernet connection of sensitive electronics such as
computers, telecommunication equipment etc. against the
effects of lightning and EMP.
USN-40001 has shielded RJ45 jacks and can be easily
installed by using of-the-shelf patch cables. For best results
shielded cables are recommended.
Input and output of USN-40001 are isolated by a magnetic
circuit which provides best protection and filtering effect in a
feed-through installation from an unprotected volume into a
shielded and protected room. However, PoE (Power over
Ethernet) is not possible with USN-40001.
USN-40001 protector/filter is designed to be used in fixed
installations (buildings, underground shelters etc.) as well as
in portable and mobile systems like containers or shelters
and vehicles, which need to be EMP-tested according to
RS105 of MIL-STD-461F.

USN-40002 Surge Protector / Filter RS422 / RS485 / PROFIBUS

Meteolabor® USN-40002 protects two wire pairs of RS422 /
RS485 / PROFIBUS interfaces against the effects of lightning
and EMP. It replaces the Meteolabor® USS-4-RS422/485/FD
in a much smaller case and has even better performance.
USN-40002 has pluggable WAGO MCS Micro terminal
blocks with locking levers and CAGE CLAMP® contacts. The
wires are easy to install by using the supplied operating tool
or a matching screw driver.
For best protection results a feed-through installation from
an unprotected volume into a shielded and protected room
is recommended.
USN-40002 protector/filter is designed to be used in fixed
installations (buildings, underground shelters etc.) as well as
in portable and mobile systems like containers or shelters
and vehicles, which need to be EMP-tested according to
RS105 of MIL-STD-461F.

USN-80001 EMP Surge Protector / Filter 10/100/1000 Mb/s Ethernet

Meteolabor® USN-80001 protects all four twisted pairs of a
10/100/1000 Mbit/s Ethernet connection of sensitive
electronics such as computers, telecommunication
equipment etc. against the effects of lightning and EMP.
USN-80001 has shielded RJ45 jacks and can be easily
installed by using of-the-shelf patch cables. For best result
shielded cables and a feed-through installation from an
unprotected volume into a shielded and protected room are
recommended.
USN-80001 also transmits up to 50V DC and can be used for
PoE applications according to IEEE 802.3af.
USN-80001 protector/filter is designed to be used in fixed
installations (buildings, underground shelters etc.) as well as
in portable and mobile systems like containers or shelters
and vehicles, which need to be EMP-tested according to
RS105 of MIL-STD-461F.
