Although the QS is designed to tolerate typical voltage variations, in today’s world the
voltage coming from the AC line may contain spikes or transients that can possibly
stress your gear and, over time, cause a failure. There are three main ways to protect
against this, listed in ascending order of cost and complexity:
•
Line spike/surge protectors. Relatively inexpensive, these are designed to protect
against strong surges and spikes, acting somewhat like fuses in that they need to
be replaced if they’ve been hit by an extremely strong spike.
•
Line filters. These generally combine spike/surge protection with filters that
remove some line noise (dimmer hash, transients from other appliances, etc.).
•
Uninterruptible power supply (UPS). This is the most sophisticated option. A UPS
provides power even if the AC power line fails completely. Intended for computer
applications, a UPS allows you to complete an orderly shutdown of a computer
system in the event of a power outage, and the isolation it provides from the
power line minimizes all forms of interference—spikes, noise, etc.
