Outdoor High Power Telephone / DSL Lightning Surge Protector - RJ11 Jacks

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.

Hyperlink's AL-DSLJW Lightning Protector features two RJ11 jacks for ease of installation. If terminal strips are needed, use the AL-DSLSW surge protector. A pair of ground lugs and terminals is provided inside the lightning protector housing, providing superior grounding.

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 the size of the cable used and are removable.

This protector is also available as a indoor model. See HGLN-DSL.
