FEATURES
TheLS50xxBseries has beendesigned to protect
telecommunication equipment against lightning
andtransientsinduced by ACpowerlines.
Its high surge current capability makes the
LS50xxB a reliable protection device for very exposed equipment, or when series resistors are
verylow.

TESTPROCEDURE :
1) Adjustthe currentlevel at the I

valueby shortcircuitingthe AKof the D.U.T.
2) Fire the D.U.Twith a surge Current: Ipp= 10A , 10/1000µs.
3) The D.U.T will comebackoff-statewithin50ms max.
