The HyperLink ALS-D25P15DW is designed to provide superior lightning and surge protection for RS-422/485 control and 15VDC 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-D25P15DW is designed to work with either 1 full duplex or 2 half duplex RS-422/485 lines. 15VDC Power Lines The 15VDC 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 c 特征
