What you Need to know about UPS

Updated: Aug 3, 2020

In today's day, we are highly dependant on electricity from the most basic to the most complex tasks. It has become a major part of our daily lives whether we're at our homes or offices. Majority of our devices depend on electricity directly or indirectly for functioning. Without electricity almost all our activities come to a halt. UPS batteries come in during such power cuts. UPS (Uninterruptible Power Supply) provides emergency power to a load when the input power source or mains power fails. This system protects your electronic devices from different power-related problems.

About UPS Batteries

UPS is used as a backup power source when the main electricity is cut off. It is generally used to protect hardware like computers, data centres, or other equipment during an unexpected power disruption which could result in data loss, fatalities, etc. UPS batteries are also used to correct common problems like

  1.  Voltage spike 

  2. Momentary reduction in input voltage

  3. Voltage sag

  4. Noise (high-frequency oscillation introduced by nearby equipment)

  5. Instability in the mains frequency

  6. Maintenance on the lines


When the main power goes off, UPS provides power with the help of its stored battery backup. It allows systems and other equipment to work properly without downtime. Once the power is back to normal, the main power takes over again. The UPS battery gets back to recharge mode after which it is ready to be used again.


Standby UPS system

Also called offline or line-preferred UPS, it consists of an inverter, battery, static switch, low-pass filter and surge suppressor. These batteries remain on standby until there’s a power loss.

Line-interactive UPS system

These systems contain a battery and inverter that are always connected to the output, and in case of power loss, a switch changes the electrical flow. The continuous connection gives excellent filtering.

Double conversion UPS system

It has a backup battery that is always connected to the inverter so that no power transfer switches are necessary. When power loss occurs, the rectifier drops out of the circuit and the batteries keep the power steady.


  • Servers and other technologies continue functioning

  • Downtime of your work would not occur

  • Productivity remains high as work isn’t interrupted

  • Does not affect any critical equipment like computers to factory production lines

  • Eliminates glitches or surges in your devices, allowing them to shut down main systems if needed

  • Safeguards your electronics against all the electrical irregularities like surges, spikes, dips and failure
