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 device works 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 the overvoltage 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..
