Computers have become a basic necessity for our survival, hence your work requires the best UPS for PC. We spend most of our time accomplishing work-related targets as professionals or completely our school assignments as students. Whatever be your designation, computer operations are super essential. But, our life comes to a steady halt when our residence suffers from a power-cut. Power-cuts are always unpredictable and inevitable. Hence, a backup plan for protecting your computer is the need of the hour. A UPS helps in achieving it. Irregular power generation should not affect the performance of your personal computer. 

What is A UPS?

A UPS stands for Uninterruptible Power Supply/Source. It is specially designed for PCs to allow them to function at their optimal level, despite a power-cut. It protects the computer system from any damage that can be caused due to a sudden power failure or unclean power. When there is a power failure in a home, all the electronic gadgets that survive through a constant power supply turn dead. When the electric current is generated again, the load on the power route is very high. Hence, the computer system may suffer from severe damage due to a heavy electric load. To avoid this, the UPS was invented. It eliminates the breakage between the computer and the power supply so that your PC can permit you to conduct your work. UPS is a chargeable device, so one can charge and keep the device ready as a precautionary measure. 

How Does A UPS Function?

The UPS bridges the gap between the computer system and the electricity supply that is formed during a power failure. It is an electronic device that permits the computer to continue functioning for a short duration when the primary source of electricity is lost. Not only do they supply electricity but also protect the computer system from power surges. It comes along with a sensor that can detect a sudden drop in the power supply. It comes along with an embedded battery that kick-starts the normal and proper functioning of the computer. The battery present within the UPS becomes a secondary source of power during a power failure. It is a backup battery that functions during the hours of crisis like a blackout, voltage sag, and voltage surge. When the sensor of the UPS detects a drop or a surge beyond the safety levels in the power supply, then it swaps to a DC battery power and converts it to AC power, so that the connected electronic device functions optimally. 

Why Is There a Need to Install a UPS?

Two main reasons are taken into consideration. First, it supplies electricity during a power failure, and second, it protects the electronic equipment from damage that can be caused due to a drop or surge in the power supply. UPS delivers the power for some time only. But, it is beneficial for the computer as the owner gets sufficient time to save his progress in the computer and successfully switch it off. Did you ever think, what is UPS for the computer? It is a provider of sufficient power. A sudden change in the graph of the power supply may cause loss of data and even severe damage to the computer. At times retrieval of data isn’t possible as the files may get deleted permanently. The computer begins to malfunction post-exposure to a voltage surge. Hence, it is advisable to invest in a good quality UPS to prevent such awful events in the future. 

Types of UPS

There are three main types of UPS available:

  • Double Conversion Online UPS: This type of UPS is successfully available to supply clean, constant, and near to perfection power, irrespective of the power source. A computer that operates on a double-conversion online UPS will function by converting the incoming AC power to DC and vice versa.
  • Voltage and Frequency-Dependent UPS: It supplies the most fundamental power. It is also called as offline UPS as it starts operating only when the inverter is turned off. 
  • Line-Interactive UPS: This type lies between the online and offline type of UPS. The load fed comes from the primary source during normal functioning. Apart from this, it consists of various levels to stabilize voltage and reduces spikes and transients.
