AL-D3W-05 - Weatherproof 3-Stage Lightning Surge Protector for RS-485 Lines
The AL-D3W-05 is designed to convert into a failsafe mode in the rare case of a catastrophic surge or lightning event. For this mode, the resistors in the second stage will fuse and portions of the diode array will short. This effectively disconnects the line from sensitive equipment thus limiting damage. The units are factory repairable.
This protector features a weatherproof ABS enclosure with gasketed cover and concealed mounting holes. Removable screw 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.
For mounting to masts up to 2 inches in diameter, the HGX-PMT25 mast mounting kit is available (sold separately).
See data sheet below for complete specifications.
- Protection for up to three pair of lines plus provisions for shielded cables
- High power 3-stage surge protection, superior to diode or TVS only based designs
- NEMA rated enclosure with gasketed cover and concealed mounting holes
- Removable screw terminals
- Ground clamp provided on outside of enclosure
