Description

The AL-D8 DC series of high power 3-stage lightning surge protectors provides superior protection of DC control

lines from transients and surges. These units will protect 8 individual single ended DC control lines. The first stage

is comprised of a spark gap. The second stage is a failsafe fuse and the final stage is a uni-polar Transient Voltage

Suppression (TVS) Diode. The unit limits the positive voltage swing on the line to the TVS Diode voltage rating.

For negative voltage swings the voltage is clamped to approximately 0.7 volts. Call for different Fuse and TVS

diode ratings. Use the AL-D8 AC series if bipolar voltage swing is required. For more complete surge protection of

control lines, the use of two units is recommended, one at each end of the line.

These units feature a weatherproof ABS enclosure with gasketed cover and concealed mounting holes. Removable

Terminal Strips are provided on the input and output for convenience. To ease installation, the terminal strips can

be removed. A ground clamp provides a tie point for earth ground.
