Ether EtherGuardian Guardian
Surge & Lightning Protection
Weather Resistant Case
Non PoE Version Item # 50590
Shireen’s EtherGuardian products 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.
Key Features:
Designed for Non-PoE devices.
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.
RoHS compliant.
1000/100/10 BASE-T Shielded RJ45 Ethernet connector.
PC Terminal Block - Spring-cage connector type for easy connect.
