People have been working from home for the last two years, and the number (of people with WFH) remains the same. Meanwhile, the demand for UPSs (Uninterruptible Power Supply) has increased. No one likes power cuts, and to work from home, you need electricity and wifi 24×7. A UPS power supply is enough to maintain the continuous power supply when there is a power disruption in your area. In addition, you can continue your online meetings and other work with a proper UPS.
Now, to buy a UPS, you need to understand the reason why it is preferred by people, its features, and its types. You must be here because you were also looking for a UPS or trying to understand the use of a UPS and how efficient they are.
This article will list all the answers to your questions. So keep reading for all those answers.
Now, let’s get to the basics.
What is a UPS?
The Uninterruptible Power Supply system has three fundamental roles to play: As a backup battery, surge protector, and power inverter. When there’s a power cut in your place, the backup battery and power inverter can supply electricity to the connected appliances/gadgets. UPS also guards against voltage spikes, variations/frequency noise, surges, harmonic distortion, and many more. Finally, it depends on the type of UPS you buy.
What are the usual power problems?
People face multiple issues with the supply of electricity. Some of them are:
- Line noise
- Harmonic distortion
- Frequency variation
- Voltage sag
- Power surge/spike
What are the types of UPS you can buy?
You can find three different types of UPS systems:
- Standby UPS
- Line-Interactive UPS
- Online UPS
The standby UPS is also known by the names Offline UPS and Voltage and Frequency-Dependent (VFD) UPS. This one is the type you can find in most places and offers essential power protection and backup battery capabilities. It works during blackouts as well as at the time of voltage surges and spikes. However, they cannot regulate power dips and transient voltage.
Line-interactive UPS is what you need to regulate power dips and transient voltage. This (UPS power supply) is the next level in power protection. If you have this type of UPS, the inverter is on 24×7 and attached to the UPS output. These UPSs have automatic voltage regulation and a transformer to keep the voltage within safe limits.
Online UPS is a double-conversion UPS, offering the maximum protection level for IT devices in healthcare centres and other institutions. It got the name double-conversion as it converts the incoming AC power to DC and vice versa.
This one prevents power delivery irregularities, stops potential power issues and delivers constant power and protection during outages, dips, surges and other common problems. Online UPS is great for cleaning up the power from generators and smoothens the irregularities in the sine wave. That’s why this (UPS) is used in data centres.
These are the types of UPS you can buy from the market. Whenever you are shopping for the UPS power supply, always look for the type which is enough to assist the electrical equipment/appliances of your institution/home/office during the electrical irregularities.
Each infrastructure/home requires a different type of UPS, and after reading the points above, you must be able to select the right one for yourself.
