Description
ST-SN301 is a 1-ch network signal surge protecting device designed according to the standard of B/T18802.21-2004/IEC61643-21:2000; The deviceworks with 5V rated operational voltage, can run on maximum continuous operating voltage 6V, with the limiting voltage under 20V.
It features multi-level protection, large maximum discharge current, low limiting voltage, quick reacting time, low inserting loss etc.. It’s adapted to theovervoltage accurate protection of the network signal like the network switch, concentrator, network card, computer etc. , protecting the damage from overvoltage, switching overvoltage, ESD etc.. It’s widely used in meeting, security, office system etc..
