Metal Oxide Semiconductors
These devices absorb any unwanted energy and therefore protect your Computer. Most Surge Protectors utilize these type of components.
Surge Protection status light
A Green light “on” indicates that the Surge Protection Circuitry is working and functional and that no worse case surges or spikes have occurred. In the event of a worst case surge a thermal fusing will close down the Metal Oxide Semiconductors and the Green light will go out to inform the user that this event has taken place.
