What is a voltage regulator? A voltage regulator is an electronic device designed to maintain a constant voltage level.
What can I protect? The main use is to protect from high voltage electrical equipment such as a computer cabinet, LCD screens, plasma screens, printers, multifunction etc.
What consumption has the team that I want to protect? See the features of your equipment to know consumption, this is identified in Volt or Watt. (With the initials VA or W).
Since consumption, what voltage regulator is for me? You must choose the right equipment to keep your voltage regulator is not working properly, once know consumption of your computer to protect or be protected multiply by two if it is in watt or use it directly if it is in VA consumption of connected equipment should be less than the capacity of the voltage regulator.
