The HyperLink ALS-D25P12DW is designed to provide superior lightning and surge protection for RS-422/485 control and 12VDC power lines. These protectors incorporate individual protection circuits for the RS-422/485 control lines and DC power lines. All housed in one NEMA rated weatherproof enclosure.

RS-422/485 Control Lines

A high power 3-stage design is used to provide protection for the RS-422/485 control line. The 3-stage design can handle higher-level transients than a protector that uses only diodes. 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 RS-422/485 control line is connected to the protector via its screw terminal blocks. The terminal blocks are removable to ease wiring. The ALS-D25P12DW is designed to work with either 1 full duplex or 2 half duplex RS-422/485 lines.

12VDC Power Lines

The 12VDC power lines are also protected using a 3-stage design. This provides superior protection from transients and surges. The first stage is comprised of a differential gas discharge tube. Stage two is a pair of suppression coils and the final stage is a 5000 Watt uni-polar Transient Voltage Suppression (TVS) Diode. Power lines are connected to the protector via high current rated screw terminals.

Weatherproof Design

These units feature a weatherproof ABS enclosure with gasketed cover and concealed mounting holes. Water tight cable glands provide entry and exit points for cables. A ground clamp on the enclosure's exterior provides a tie point for earth ground.

For mounting to masts up to 2 inches in diameter, the HGX-PMT24 mast mounting kit is available (sold separately).

This protector is also available in the following power configurations:

    15VDC: ALS-D25P15DW
    24VDC: ALS-D25P24DW
    12-28VAC: ALS-D25P1228AW
