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.
