Power protection and voltage regulation differences.

Q: “Generally speaking, what’s the difference between power protection and voltage regulation?”

A: Devices that offer power protection (or power conditioning) protect from potential damage caused by voltage spikes and -in some cases -extreme voltage from faulty wiring. They generally also offer filtering of phenomenon such as EMI and RFI in the electrical signal. Power protection devices do NOT stabilize line voltage. Low voltage or over-voltage conditions must be corrected by a voltage regulator, which uses voltage-sensing circuits and other circuitry to keep voltage stable at 120V or 240V within a specified narrow range.
