Description
The AL-CAT5SHPW CAT5 three-stage Lightning Protector provides superior
lightning and surge protection for both indoor and outdoor 10/100 Base-T
networks. In addition, the unit is compatible with Power-over-Ethernet (PoE)
devices. Integral to the design is protection for the two Ethernet data pairs
and the PoE DC power feed.
In the data path, the first stage of protection is a differential gas discharge
tube. Stage two is a pair of current limiting series resistors and the final
stage is a high speed, low capacitance diode clamp array. In the power path,
the first stage is comprised of a differential gas discharge tube. Stage two is
a dual low pass filter and the final stage is a triple array of bi-directional
clamping diodes. The unit supports normal and reverse polarity PoE.
Failsafe Architecture
The Advantage of this three stage surge protector design is the added level of protection due to its large power
rating and safety due to its failsafe architecture. In the event of a catastrophic surge event, the series resistors
will fuse and the shunt diodes will short. This will safely disconnect the line from the datacom equipment.
The AL-CAT5SHPW CAT5 Lightning Protector is compatible with Wireless Access Points, Access Servers and
Outdoor Routers, with or without Power-over-Ethernet (PoE) functionality. A ground clamp provides a tie point for
earth ground. For maximum protection from lightning on long cable runs, two units can be used, one at each end
of the cable.
