Howdy Folks

So we all know that a Professional Surge protector Strip used in top of line Stereo equipment is needed to protect or Modern Pachinko and Skill Stop Slot but it has come to my attention that the Power coming from our grounded home sockets might not be "Clean Power" it could be not 60 herz (USA) or 50herz (Europe) or lower or higher than 120vac or 220vac .

Some of the best ups have Automatic Voltage Regulation so the voltage surge and voltage under surge (brownouts) don't get to our stuff.

When the U.P.S. Goes on batteries cause of a power outage the 60 or 50 Herz might not be getting to our devices and that could cause damage.
