Before you hop to any decision about the best UPS for computer in India, you should be aware of the types of UPS systems. UPS stands for uninterrupted power supply. It is like a power bank to support your computer in a blackout situation. Also, it will save your laptop from frequency variation, overvoltage, and power surge/spike.
Types Of UPS Systems
UPS systems can be categorized into three broad categories according to their power supply. They are Standby UPS, Line Interactive UPS, and Online UPS.
Standby UPS
It is also called an offline UPS or VFD (voltage and frequency-dependent) system. It can protect your computer from blackouts and voltage surges and spikes. But it can't help in situations like power dips and transient voltages. With a standby UPS, you'll only get a power supply for 5-20 minutes so you can shut down your computer system in a blackout situation. You can buy UPS online in India for small, non-critical electronic devices.
How Does A Standby UPS Work?
Upon sensing a blackout or increase in voltage, the UPS transfers the load to the inverter output. And it takes just 5-8 milliseconds to switch the power solution. But it creates a pseudo/square sine wave output waveform that could result in overheating, malfunctioning, or equipment failure in electronic devices.
Line-Interactive UPS
It is a better option than offline UPS as it incorporates Automatic Voltage Regulation (AVR) technology. In the event of a frequency drop, a standby UPS switches to battery power, but a line-interactive UPS will maintain the connection. It is for this reason that it is considered one of the best power backup solutions available on the market.
How Does A Line-Interactive UPS Work?
The system is part of the output and is therefore always connected. When the input AC power is normal, the inverter is reversed to charge the battery. In a blackout situation, power is automatically transferred to the inverter. And it takes only 4-8 milliseconds to switch on the inverter power. But a Line-Interactive UPS delivers pure sine wave output that makes it suitable for most devices. And it can power up to 4,000 watts of connected systems. If you want more power, you can switch to Online UPS.
Online UPS
It is also called an online double-conversion UPS as it converts the incoming AC power to DC and then converts the DC power to AC to support the connected systems. And this technology makes it the best online UPS in India. Its advantage is that it protects against all electrical problems, including power outages, surges, and falls. It can also clear power from the generator by removing any irregularities in the sine wave.
How Does An Online UPS Work?
It provides a consistent AC power supply to connected systems. And it has no downtime in the event of a power outage. But the same cannot be said about standby and line-interactive UPS systems. Also, the output regulation of online UPS is much more accurate than others. It keeps the normal voltage plus or minus 2-3% so that the connected gadgets are not damaged by power instabilities.
Final Thoughts
Depending on your needs and budget, you can buy the best UPS for computer in India. If you are looking for UPS for your home PC, you can buy standby UPS, but if you need better performance then go for Line-Interactive UPS. Also, go through How Much Should You Invest in Power Backup Solutions?
