TII hybrid Powerline Surge Protectors use the synergistic action of Metal Oxide Varistors (MOVS) and the TII Maximum Duty gas tube arrester to guard against dangerous and destructive poweline surges caused by switching, lightning and other transient sources.

A major producer of overvoltage and surge protection products for the telecommunications Industry for more than 25 years, TII has designed a combination of components that provides superior protection characteristics on ac powerlines.

These components are a hybrid of very fast acting solid state devices and very high power dissipation gas tube devices. Together these components act in a way that is superior In performance to that which any arrangement of either component used alone can provide.

systems. Metal Oxide Varistors (MOVs) respond to fast rise time, lower energy content pulses and limit the peak voltages seen by the protected equipment. On higher energy surges, the major portion of the surge current will be diverted from the MOV to the gas tube which can handle many times the peak current of an MOV or an avalanche diode. This sharing of surge current again limits the peak voltage seen by the protected equipment

As both Industrial and consumer electronic equipment becomes more sophisiticated, it has become more obvious that additional protection techniques beyond those used in the past will be required. In some instances products that only limit peak voltages will not be sufficient and additional circuitry will be necessary.
