ATLAN 24 POE - Surge protection for POE computer networks. 1 GBit/s. RJ45 input/output connectors. C2 Test (2kA/4KV). Up = 200V. Includes 24 cables with RJ45 connectors, 0,5 m long and 19'' rack.
ATLAN protectors are especially designed to prevent failures in data transfer between equipment within the same network. They protect the electronic circuit inputs of the network cards against damage due to transient currents.
ATLAN 24 is an SPD for 24 lines protection with four pairs protected per line. This is done using a printed circuit board with RJ45 input/output connectors, able to withstand current up to 2 kA for each line and with a transfer speed of Gbits/s.
It is especially designed to be inserted into a rack and protect computer network distribution cabinets. Due to its high transfer speed, it is suitable for networks transferring a large amount of data (servers, workstations, graphic stations etc). Includes 50 cm output cables with RJ45 connector.
Tested in official and independent laboratories, obtaining their characteristics according to relevant standards (shown in the table).

INSTALLATION

Protection should be installed as close as possible to the equipment. In this particular case, we are talking about switches and hubs.

If there are two pieces of equipment located in separate buildings but linked together, the protection must be installed on both sides of the line.
The recommended procedure for installation is the following:

  • Screw the protectors onto the 19 inch rack for computer network distribution.
  • Run the network distribution lines from the hub or switch to the protector.

SAFETY AND MAINTENANCE

Connection to earth is a must. Earthing in the whole installation must be bonded either directly or by a spark gap and resistance should be lower than 10 Ω.

If the indications on this datasheet are not fulfilled during use or installation of the protectors, the protection provided by this device could be compromised.
