VHSK1072 Very High Speed Data Line Protector

 

· Product Description

The VHSK1072 is a multistage protection moduledesigned for the protection of digital telephone and datacircuits against transient over-voltages caused bylightning, induced impulses and other voltage surges.Traditional shunt-connected gas filled arresters bythemselves can no longer provide adequate or requiredprotection for sensitive line cards or newer generationdigital switching systems.

The VHSK1072 contains ten line protection circuits on asingle PCB. Each circuit consists of a primary threeterminal gas filled arrester followed by a secondarytransient clamping circuit.

The gas arrester provides common mode protection bybypassing transient currents to ground. The arresterchosen by LPI has a fast impulse response compatiblewith the requirements of advanced high speed datanetworks.

The secondary transient clamping circuit comprises aseries resistor in each leg plus shunt connected silicontransient protection devices.The effect of this series impedance is to providedecoupling between the primary and secondary protectionelements during fast rise time impulses associated withlightning type transient events.

The effect is that fast risetime events, with high dV/dt, are diverted to the primarygas filled arrester rather than passed through to theequipment.

Following the series impedance, silicon transientprotection devices provide transverse mode fineprotection.

The VHSK1072 is earthed through two spring clips whichconnect to the KRONE LSA* frame. These robust tabsprovide excellent electrical contact with the frame.
