In Pakistan, thy have a lot of load shedding. So people adapted something called a UPS; which had been used in the military, government offices, industry and hospitals for many years.. Basically it helps people of Pakistan still have enough electricity through that time.

What it does is that it has a battery that it charges when there is electricity so when there isn't any, they have a little bit that they can use on fans, singular light bulbs and some more items. A more sophisticated UPS and inverter will supply AC at domestic voltage.

When purchasing a ups you have to macth the power needs of your system according to what unit of measure?

When purchasing a UPS (Uninterruptible Power Supply), you need to match the power needs of your system according to the unit of measure called volt-amperes or VA. This ensures that the UPS can support the power requirements of your equipment and provide sufficient backup power during outages.


What-voltage hz not use in Pakistan?

Not used in Pakistan: frequencies other than 50 Hz. For domestic and small businesses: voltages other than 220 v.


Why 220V are used in Pakistan as standard home voltage?

Because that allows a wide range of manufactured electrical goods from all over the world to be used in Pakistan. Voltages are standardised to 120 v or 230/240 v throughout the world.


How do UPS systems work?

UPS is abbreviated as Uninterrupted Power Supply. As the definition itself states, it is a power supply which prevents interruption due to some factors such as power cuts or power failure. UPS plays a very important role in industrial sector especially IT where loss of critical is saved due to UPS. Whenever we get a power cut the UPS comes in play and switches itself with the power supply to avoid interruption or loss and supplies power stored in it. Moreover it also doubles up as a voltage regulator thereby protecting the system from voltage drop and high voltages
