Shireen Inc. EtherGuardian offer multilevel protection to Gigabit Ethernet devices. Offered in an outdoor weather resistant box, the unit can also be used indoors for protection of your sensitive network equipment for electronic static discharges (ESD), cable discharge events (CDE), electrical fast transients (EFT) and lightning. These units comes with rainproof case for outdoor applications.

Key Features:
  • Solid-state silicon-avalanche diodes with internal TVS.
  • Operates at low voltage, clamping voltage and capacitance.
  • High speed data line ESD protection: IEC 61000-4-2,-4-4,-4-5.
  • Broadband optimized Thyristors protection.
  • Trigard Miniature 3-Pole gas discharge tubes.
  • Overcurrent protection switch (PoE versions only).
  • RoHS compliant.
  • 1000/100/10 BASE-T Shielded RJ45 Ethernet connector.
  • Available designs for PoE (802.3af Standard Mode B) and Non-PoE devices.
  • PC Terminal Block – Spring-cage connector type for easy connect (PoE Mode A or B flexibility).
