Description
Superior Performance
The AL-DSLJW is HyperLink’s outdoor version of its HGLN-DSL protector. This Phone/DSL 3-stage Lightning Protector provides
superior lightning and surge protection for Telephone and DSL lines. The unit is fully compatible with dedicated and shared DSL
and phone lines. Shared phone lines carry the ring voltage for standard telephones. The unit protects against both differential
and common mode transients.
The first stage is comprised of a differential gas discharge tube. Stage
two is a pair of current limiting series resistors and the final stage is a
low capacitance diode array. The use of three terminal differential gas
discharge tubes provides superior protection against surges. The second
stage series resistance limits the power dissipation of the faster diode
clamp array in the third stage. This allows time for the slower but higher
power gas tubes to turn on. The diode array clamps the leading edge of
fast transients to safe levels until the high power gas tubes turn on. This
eliminates the damaging leading edge spike that single stage gas tube
protectors let leak through. The 3-stage design can handle higher-level
transients than a protector that uses only diodes.

Outdoor Use
The compact weather resistant housing features a lockable hinged cover and mounting holes are provided on the rear of the
enclosure for mounting. The two cable grommets may be adjusted to cable size and are removable.
