1. Alternatively referred to as a brownout, dip, sag, voltage reduction, and voltage sag, a voltage drop is any decrease in voltage, typically under one second. Longer reduction in voltage is called undervoltage.
Power
line sags often occur during the summer and when too much equipment is
plugged into the same circuit. When this occurs your computer could
experience such symptoms as the computer locking up, lost data, system
crashes, and can also cause hardware in your computer such as the hard
drive to fail.
Tip: If your area experience brownouts, we
recommend purchasing a SPS or UPS for your computer and other essential
equipment to help prevent any damage and corruption.
