DESCRIPTION:TRIBALANCED PROTECTION
Dedicated protection devices for ISDN LINE
CARDand high speeddata telecomlines.
Usedwiththerecommendedconfigurationusing
3 components,theywill provide=
-Dualbidirectionnalprotection,with fixed
breakdownvoltage in bothcommonand
differentialmodes.
-Low capacitancesfromlines to ground.
-Verygood capacitancebalance: ∆C= 30 pF.
