Small LED Light As Indicator In A Surge Protector
However, the most beneficial advancement of late is that small LED
bulbs are now utilized as indicator lights in the device that protects
equipment from power surges, the surge protector. Surges, otherwise
called voltage spikes or transient surges, are abrupt increases in
household voltage what happen when high-energy appliances or computers
are powered on. Such surges can take place in excess of 2,000 times
per year in homes, slowly destroying the components of a home

===== Is this sentence true. Many times a year? And more
importantly, *slowly* destroying. Not ruined or "no damage"?

computer, a cell phone, and other fragile electronic equipment. Other
home appliances, furnaces, air conditioners, washers, dryers, and the
like, are also know to create surges which travel back through the
main breaker panel and out again through the home wiring.


Anything with a modern switching power supply is immune from anything the
power company "surges", usually caused by loose neutral connections
causing an unbalanced phase voltage, can cause. Switchers are rated from
around 80VAC to 270VAC (not cast in stone) and will simply absorb any
voltage changes as the input of these supplies is just a big rectifier
with big storage capacitors to feed DC to the switching regulators.
Surges are turned into output power, nicely leveled by the fast
switcher's reaction time. Your computer power supply is one of them.

What's FAR more important than a "surge protector" it doesn't need is a
UPS to hold up the AC line voltage on brownouts and interruptions that
just love to occur during those all-important disk write
operations....leaving the disk trashed with half a FAT updated and half a
FAT not. That's better than a good hacker can ever achieve trying to
trash a system!
