What Makes Your UPS System Tick

Have you ever experienced rushing a job in the office for a couple of hours when suddenly, a power failure happened! Many types of electronic equipment have been damaged internally because of the sudden surges of power before. That was until 1934 when they first completed the Uninterruptible Power Supply (UPS) in the USA.


What is a UPS?

A UPS is an electrical device that provides backup power when the main power source fails. Unlike a backup generator, a UPS is different because of the protection it offers. It provides immediate protection from power disruptions through electronic circuitry (for minimal power users), and flywheels (for high power users).  Batteries are the heart of UPS Systems. It usually lasts for 5-15 minutes, enough time to bring an auxiliary source or backup generator online. If there are no backups, 5-15 minutes are enough to shut down the equipment properly.


What can a UPS protect?

It is usually used primarily to protect from an unexpected power disruption that could cause harm, casualties, critical business disruptions, or data losses to:

  • Computers
  • Telecommunication Equipment
  • Data Centers
  • Other Electrical Equipment


Specific Levels of Power Protection 


  • Standby

It is the most basic UPS feature. It goes to battery backup power when common power problems. When the power drops or surges above safe voltage levels, the UPS switches to DC battery power and then inverts it to AC power to run devices. It is for consumer electronics, entry-level computers, Point Of Sale (POS) systems, safety systems, and other basic electronics.


  • Line Interactive 

It integrates C & D Technologies that allow the correction of minor power instabilities without switching to battery. It is for PC-gaming systems, network devices, home theater electronics, and entry-to-mid-range servers.


  • Double-conversion (Online) 

It provides reliable, orderly, and almost perfect power regardless of the situation of incoming power. It converts incoming AC power to DC, and then back to AC. It works on isolated DC power 100% of the time and has zero transfer time. It never needed to switch to DC power. It protects from damages caused by a power blackout, voltage sag & surge, harmonic distortion, frequency noise, frequency variation, or voltage spikes. It is for IT equipment and data centers used for critical operations, high-end servers, advanced network equipment, and mega telecom installations.
