A power conditioner is a device that protects electrical equipment from power fluctuation and delivers stable power supply to enhance performance. There are different synonyms for the term, depending on the specific functionality of the device. Voltage regulator and surge suppressor are the most common synonyms that ensure stable voltage output and protect devices from sudden power arc. Line conditioner is another synonym that performs the same function of voltage regulation with the additional feature of eliminating electrical noise. Power stabilizer operates like line conditioner but also corrects power factor, while power protector safeguards equipment from overvoltage, under voltage, and other electrical spike-related issues. Regardless of the name, power conditioners ensure the longevity of electrical equipment, prevent downtime and potential losses.
