What is the difference between online UPS and line-interactive UPS?
When not operating from the battery, line- interactive UPS systems typically regulate output within ±8-15% of the nominal voltage (e.g. 120, 208, 230, or 240 volts), whereas online UPS systems typically regulate voltage within ±2-3%.
What is UPS line-interactive?
A Line-interactive UPS is one type of uninterruptible power source that can regulate voltage automatically. The line-interactive technology responds to high and low voltage conditions. Units also support systems during outages without battery drainage.
What is a true online UPS?
Under normal operation, a true online UPS runs continually on the battery via the inverter, while the line power runs the battery charger. In some cases, this type of UPS is called a double conversion, or double conversion online. In the event of a power failure, the unit operates like a regular true online UPS.
What is the advantage of online UPS over off line UPS?
Advantages of Online UPS: It provides isolation between main supply and load. Since inverter is always ON, the quality of load voltage is free from distortion. All the disturbances of supply such as blackout, brownouts, spikes etc are absent in the output. Voltage regulation is better.
How do I choose a UPS for my computer?
The more power that is consumed, the less time the UPS will be able to power everything. When choosing a UPS, it is generally recommended you chose one with an output watt capacity 20-25% higher than the total wattage of the devices you want to connect. You can use the UPS watts calculator to determine your total load.
How do I use Line-Interactive UPS?
Line-interactive UPS—Intermediate Level Power Protection When the input AC power is normal, the inverter of the UPS is in reverse operation and provides battery charging. Once the input power fails, the transfer switch will open and the power will flow from the battery to the UPS output.
Which is the best UPS for computer?

How many types of UPS line-interactive?
The three major types of UPS system configurations are online double conversion, line-interactive and offline (also called standby and battery backup).
What are the advantages of online UPS?
Online UPS
- Better voltage regulation.
- Conversion time from DC to AC is negligible with no gaps in coverage.
- No fluctuations in the voltage, indicating stable voltage quality.
- The quality of the load voltage is free from distortion.
- Near ideal electrical output, highest protection against all power irregularities.
How does line interactive UPS work?
A line interactive UPS incorporates technology which allows it to correct minor power fluctuations (under-voltages and over voltages) without switching to battery. This type of UPS has an autotransformer that regulates low voltages (e.g., brownouts) and over voltages (e.g., swells) without having to switch to battery.
What is interactive UPS?
A line interactive UPS (uninterruptible power supply) can be loosely described as an offline unit with a much greater level of voltage stabilisation and power conditioning.
What is “double conversion on-line ups”?
Double Conversion On-Line UPS is the same as the Standby UPS except that the primary power path is the inverter instead of the AC mains. In the design of Double Conversion On-Line operation, failure of the input AC does not cause activation of the transfer switch, because the input AC is not the primary source, but is rather the backup source.
What is line interactive topology?
Line Interactive. Line-Interactive topology incorporates technology that allows the UPS to correct minor power fluctuations (under and over voltages) without switching to battery.
