Use on lines running within buildings Use to protect twisted pair applications using Cat 3, 4 or 5 cabling with RJ45 connectors. Suitable for systems signalling on up to 8 wires of unshielded twisted pair cable. Use to protect 1, 4, 8 or 16 lines. Suitable for RS 422/423, 10 Base-T, 100 Base-T, Token Ring, and Fast Ethernet Systems. Available for individual connections or for multiport applications. Free standing or 19" rack mounted versions available for multiport applications.
For coaxial Ethernet cables running external to the building use the ESP Thin/ThickNet models. For Cat 3, 4 or 5 cabling with RJ45 connections running external to the buildin use the ESP Net-100. Local protection for PCs and computer communications with D type connectors running within a building use the ESP L/LB series.
Application
Use on network cables running within a building to protect systems locally from transients induced onto data cables from the magnetic field caused by a lightning strike.
Features and benefits
Let-through voltage below equipment susceptibility levels.
Protects twisted pair lines operating at speeds up to 100Mbps.
Protects all 8 pins in each line.
Protect the network connection to individual pieces of equipment with the ESP LN.
Protect multiport applications such as hubs, switches and patch panels with the ESP LN-4*, ESP LN-8*, ESP LN-8/16 or ESP LN-16/16.
Available as 4 or 8 port free standing versions (ESP LN-4* and ESP LN-8*) and 8 or 16 port 19" rack mounted panels (ESP LN-8/16 and ESP LN-16/16).
PROVISIONAL - (Contact Keison Products for the latest information)
Negligible in-line resistance.
Sturdy housing.
Simple plug-in installation.
Simple earthing via single braided metal strap.
* Note: ESP LN-4 and ESP LN-8 are not shown.
Installation
Plug in connection between incoming data cables and equipment to be be protected. Make suitable attachment to earth.
Technical Note
ESP LN... range of protectors are designed only for use on cables running within a building, and therefore will not be able to handle the higher level transients that occur when lines between buildings are protected. They should not be used in such an application. If they are used in lines between buildings, there is a high risk of the protector being overloaded and destroyed during transient activity. Connected equipment will, in most cases, still be protected, but there is a small risk that equipment will suffer damage in such circumstances.
