Guys, UPS, also known as battery backup, provides backup power when your regular power source fails or the voltage drops to an unacceptable level. A UPS allows for safe, serialized shutdown of computers and connected devices. The size and design of the UPS determines how long it will supply power. But there are not only enough to know about it.
Definition of UPS
A UPS is a hardware device that provides a backup power source in case of a power outage (blackout), brownout, or an increase in power supply.
Full Form UPS
The Full Form of UPS is –
Uninterruptible Power Supply
UPS means – Uninterruptible Power Supply. UPS also stands for Uninterruptible Power Source also known as Battery Backup.
That was all basic we need to know about UPS – Uninterruptible Power Supply. Let us dive deep into the knowledge about UPS and get to know more about it.
What is UPS
Usually UPS power keeps a personal computer (PC) on for a few minutes after a main power failure, allowing you to save your data and shut down the computer correctly. Many uninterruptible power suppliers now offer a software component that can enable automatic backup and shutdown processes when a power failure occurs while you are away from the computer.
In many cases, UPSs are included in the main computer or monitor itself, but depending on the size of the UPS, other devices may also be plugged into the UPS for backup power.
In addition to acting as a backup when the main power is gone, most battery backup devices also act as “conditioners” that ensure that your computer and accessories are free of power drops or surges. Ho.
If the computer is not receiving a continuous power supply, damage can often occur. UPS is commonly used in computers, data setters, communication equipment or other electrical devices where unexpected power disruptions can cause damage or data loss.
While a UPS system is not an essential part of your computer system, it is always advisable to use it.
Battery backup is between the main power (power from the wall outlet) and the computer. In other words, computers and other accessories are plugged into the battery backup and plugged into the battery backup wall plug.
UPS devices come in many sizes and shapes, but are usually of rectangular and freestanding style, intended to be placed on the floor near the computer. All battery backups are very heavy due to the battery inside.
One or more batteries inside the UPS provide power to the devices connected to them when power from the main outlet is not available. These batteries are rechargeable and often replaceable, providing a long-term solution for your computer system.
The UPS usually has a power switch to turn the device on and off. Larger UPS have one or more additional buttons or even touch panels, which display various functions. Some high end UPS also often have LCD screens which display information about how much battery is charged, how much power is used, etc.
The back of the UPS will feature one or more outlets that provide battery backup. In addition, many battery backup devices also include the surge protection feature in additional outlets and sometimes have network connections as well as protection for phones and cable lines.
UPS are manufactured with varying degrees of backup capability. To determine how much power UPS you need, first, use the Extreme Power Supply calculator to check the watt required for your computer. Also check the Watt of other devices and take their total number and contact the UPS manufacturer to know how long you need backup.
Typically a 600V UPS is sufficient for 10-20 minutes of power backup to a home desktop computer.
Why UPS is needed?
The development of electronics and computer base devices, as well as the use of passive electronic devices such as personal computers, super computers, data processors, digital controllers, etc., increased. Such devices require interrupt free power supply, as these devices handle data with Memory and Processor.
As we know that these devices are very sensitive to the corrupt power supply. For example, if you shut down your personal computer directly by removing the power plug instead of shutting down, you will lose your data and sometimes the operating system of your computer may corrupt. Therefore, it is necessary to provide an interception free power supply to these devices to protect big data in large scale industries. UPS is used to fulfill this requirement.
Parts of Uninterruptible Power Supply
Like every other electronic device, even UPS is also made up of numerous parts which are required for its functioning. Out of all of these, the main parts of UPS are :
- Rectifier (Battery Charger )
- Static Switch or Contactor
Function of a Rectifier in a UPS
As we all know that the main function of rectifier is to convert AC into DC. It is used to charge the battery and it hangs in the inverter circuit. Its output depends on the load requirement.
Function of Battery in a UPS
The battery stores energy, which is used for future use if the main power fails. This battery can be lead acid or any other type as per requirement.
Function of an Inverter in a UPS
This reverses the rectifier process. It converts incoming DC supplies to AC for load use. The output of the inverter is sinewave. This D.C. Converts to A.C of constant frequency and amplitude
Function of a Static Switch or Transfer Switch:
A static switch or transfer switch is required to transfer the source of power. The time of this operation is very fast. Typically, switches that operates within 10 milliseconds are used.
Types of UPS
There are different types and categories of UPS made up for different purposes. Different types of UPS includes:
- The Standby UPS
Standby UPS are the most common type and are used for personal computers. It only starts when the power fails, hence its name “standby”.
- The Line Interactive UPS
Line Interactive UPS is the most common design for small business, web and departmental servers. In this design, the battery to AC power converter (inverter) is always connected to the output of the UPS. The operating inverter provides battery charging in reverse when the input AC power is normal. When the input power fails, the transfer switch opens and the power flows from the battery to the UPS output.
With the inverter always connected on and output, this design provides additional filtering and yields and has fewer switching transients than the standby UPS topology.
- Standby On-Line Hybrid
Standby on-line hybrid is a topology used for multiple UPSs below 10kVA labeled “on-line”. As with standby UPS, when AC power fails, the battery switches the standby DC to DC converter.
The major work of UPS is to provided a temporary power supply in case there is a power supply failure.
Yes. The all purpose Personal Computer UPS can be used to provide a backup to the laptop too. But it should be noted that it can’ t provide a longer duration of Power Backup.
