The Ups: a thought or two.
A Ups short for interuptable power supply is to condition electricity for the equipment connected to the unit. Usually not all lines are used for that. Some of the power receptacles (where you plug in things) can be used for surge protection only. Usually the conditioned power receptacles will say they are for using battery backup and surge protection. Since I mentioned the unit is for line conditioning, the ups will smooth out or clean the power coming in the the devices the ups protects. It also should protect against extreme situations such power surges and brownouts. Most people know about power surges, such a protection against such dangers as lightning strikes. Generally that is true if the lightning strike is not a direct hit to your power lines. Some electricity companies will install special surge protection on a home or building making it not usually necessary to have to use surge protectors in the building. What a lot of people do not know about is brownouts...
