• Very High Speed data line protection for 10 pair Krone LSA-Plus
• High Bandwidth - 12 MHz (-0.3dB, 120Ω)
• Effective clamping with lower let-through voltage
• High reliability surface mount technology
The VHS-K10 is a multistage protection module designed for the protection of digital telephone and data circuits against transient over-voltages caused by lightning, induced impulses and other voltage surges. Traditional shunt-connected gas filled arresters by themselves can no longer provide adequate or required protection for sensitive line cards or newer generation digital switching systems.
The VHS-K10 contains ten line protection circuits on a single PCB. Each circuit consists of a primary three terminal gas filled arrester followed by a secondary transient clamping circuit.
The gas arrester provides common mode protection by bypassing transient currents to ground. The arrester chosen by LPI has a fast impulse response compatible with the requirements of advanced high speed data networks.Thesecondary transient clamping circuit comprises a series resistor in each leg plus shunt connected silicon transient protection devices.
The effect of this series impedance is to provide decoupling between the primary and secondary protection elements during fast rise time impulses associated with lightning type transient events. The effect is that fast rise time events, with high dV/dt, are diverted to the primary gas filled arrester rather than passed through to the equipment.
Following the series impedance, silicon transient protection devices provide transverse mode fine protection.
The VHS-K10 is earthed through two spring clips which connect to the KRONE LSA* frame. These robust tabs provide excellent electrical contact with the frame.
