3-stage Indoor Lightning Surge Protector for RS-232 Sensors and Control Lines
Model: HGLN-D2-12
- Industrial grade
- 3-Stage surge protection
- Cast aluminum construction, integral mounting feet
- Protection of digital or analog signal or control lines & provision for shielded cables
- Superior to diode or TVS only based designs
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 use of three terminal differential gas discharge tubes provides superior common and differential mode protection against conducted transients versus the use of lower cost two terminal tubes. The second stage series resistance limits the power dissipation of the fast diode clamp array in the third stage. This allows time for the slower but higher power gas tubes to flash over. The diode array clamps the leading edge of fast transients to safe levels until the high power gas tubes turn on. This eliminates the damaging leading edge spike that single stage gas tube protectors let leak through. The diode array's low capacitance assures that the suppressor will not degrade the high-speed signals. The 3-stage design can handle higher-level transients than a protector that uses only diodes.
For more complete surge protection of data lines, the use of two units is recommended, one at each end of the line.
For outdoor applications, this protector is also available in a weather resistant enclosure. See AL-D2W-12.
