Description

High voltage transients caused by lightning strikes have the ability to easily destroy semiconductor

junctions, and thus, cause equipment failure and loss. A lightning strike close to data lines can also cause

induced currents in lines that can also do serious damage. The AL-D4W-DT high performance lightning

protector provides superior protection of DSL and Telephone lines from these transients or surges.

The low capacitance diode array minimizes degradation of the DSL signal. This is in comparison to

protectors based on high capacitance TVS diodes or Varistors. The high speed diode array responds to transients that are too

fast for Gas Tube based protectors to catch. In addition, the design utilizes Thyristor diode technology which has superior power

handling capability compared to TVS or Zener diode based designs. The unit will protect up to 4 signal pairs. For more complete

protection, two units should be used, one on each end of the line.

The compact weather resistant housing features a lockable hinged cover and break-away holes are provided on the rear of the

enclosure for mounting. The cable grommet may be adjusted to cable size and are removable.
