What a UPS Does?

  • If your Raspberry Pi project needs to be powered all the time relying solely on the mains power system may leave you in strife. Dropouts and surges can be regular occurrences depending on your location and these often last a couple of hours.
  • Any power fluctuation can be harmful to your Raspberry Pi and a power outage will shut down your Raspberry Pi instantly. This means it will not shut down safely which results in any information being written to the SD becoming lost and increasing the potential for corrupting all of the information on your SD Card.
  • A UPS ensures that if a power interruption occurs with the main supply (interruption = blackout), a battery or another power source will jump in, take over the role of the mains supply and continue normal operation of the device without the system ever losing power. Often UPS is seen as the emergency power method. When the mains are repaired the UPS is then recharged ready for the next calamity.
