Uninterruptible Power Supply

The uninterruptible power supply in the full name of UPS.

The ups are a device that provides uninterrupted power to us anytime and anywhere which is a common electrical device.

This is used when the main power source fails. It plays the role of an auxiliary in which batteries and supercapacitors are used.

The Main Role of UPS:

Ups work to provide short-term power supply when your mains power supply is disrupted.

Also, it can operate at different temperatures and is also effective in correcting small and large power problems such as power increase or decrease.

This is mainly divided into 2 types.

1.Online ups

2. Offline ups

1. Offline UPS:

This is also known as a standby unit that provides only basic needs. It is given filtered AC power in the primary phase. Whenever the power fails, the transfer switch selects its backup power.

This system acts as a backup when there is any interruption in the main power supply. In this system, the alternating current is already kept low. And is attached to a battery unit connected to a rectifier

When any kind of power is broken, the system comes into motion and the power in its battery is forwarded from DC to AC with the help of an inverter and the load connected to it is supplied.

This system has proven to be cheaper and less costly. It provides more features besides backup. The transfer time can be about 25 milliseconds.
