What is UPS (Uninterruptible Power Supply)?


UPS is an abbreviation for Uninterruptible Power Supply, and its name comes from the fact that it provides a continuous supply of power without interruption. It draws current from the mains in normal operation and from its backup source during a power outage.


As a backup source, a UPS system uses DC power stored in a battery. A Rectifier and charge controller circuit in the UPS charges the battery from the AC mains. At the same time, it powers the output AC load. In the event of a power outage, the UPS uses the charged DC power in the battery to convert it to AC via an inverter and supply it to the AC load.

The switch between sources (AC mains and battery in case of power outage) is now instantaneous. It does, however, take time. Some sensitive electronic equipment may be affected by this time delay during switching, while other devices may tolerate it within a certain range. This is where Online UPS and Offline UPS enter the picture.


What is Online UPS?


The Online UPS is a type of UPS that normally supplies power to the AC load via the Rectifier and Inverter Combo and uses an inverter to supply power during a power outage. As a result, the output power supply is always on and no switching is required. As a result, there is no time lag when switching between its sources. Even if the power goes out for a nanosecond, there is no interruption.


During normal operation, a rectifier converts the AC supply from the mains into DC and a charge controller circuit charges the battery. At the same time, the DC power from the charged battery is being converted into AC and supplied to the output AC load via an inverter.

In the event of a power outage, the UPS will stop drawing current from the alternating current mains and will stop charging the battery. However, the AC load will continue to draw current from the battery via the Inverter.


As a result, when switching its power source, Online UPS has no time delay. It is also known as an Online UPS because it remains operational even when not in use.


When Should You Use Online UPS?


  • When to use continuous power supply without switching operations for sensitive and important devices and equipment.
  • When the main power supply fluctuates frequently or when the daily scheduled load shading and power outage occurs.
  • When there are no concerns about the cost of operation, installation, and maintenance because the online UPS system is more expensive than the offline UPS system due to the additional parts in online uninterruptible power supply.
  • When you require the simultaneous operation of multiple connected devices for an extended period of time.


What is the difference between online and offline UPS?


The two most important types of UPS are online UPS and offline UPS. Both provide power to the device in the event of a power outage. The similarities, however, end here. The primary distinction between Online UPS and Offline UPS is that the Online UPS provides power via a rectifier and inverter combination. It supplies power to both the load and the battery at the same time, allowing the battery to be charged and ready to go in the event of a power outage.


An Offline UPS, on the other hand, supplies AC power directly to the load by turning on the transfer switch. In the event of a power outage, the offline UPS draws power from the battery backup. Another significant distinction between Online UPS and Offline UPS is the requirement for a large heat sink.


The rectifier in the Online UPS supplies power directly to the inverter as well as the battery. As a result, heat dissipation will be significant. As a result, an Online UPS requires a larger heat sink than an Offline UPS.

Frequently Asked Questions


Q. What is online UPS and inverter?

Online UPS is a UPS type that supplies power to the AC load in normal operation and uses an inverter to provide AC power during a power failure. In Online UPS, the output power supply always stays ON i.e. the UPS keeps charging the battery and draws current from the battery to supply the load.

Q. Can online UPS be connected to inverter?

Yes. for this purpose, Do not connect input voltage (230V AC). Only Connect Battery input.

Q. Which is the best UPS inverter for home?

Lento Online Static UPS Inverter is by far the best inverter for home.

Q. What is Online UPS?

The Online UPS is a type of UPS that supplies power to the AC load through the Rectifier and Inverter Combo in normal operation and uses an inverter to supply AC power during a power failure. Therefore, the output power supply always stays ON and there is no need for switching.

Q. Which is better between online and offline UPS?

The inverter is ON in power outage as well as during power availability. The inverter is ON only when the power failure occurs. The online ups is less reliable because it is in ON state always. The offline UPS is more reliable because it is in ON state only during power outage and thus its efficiency is high.

Q. What is the benefit of online UPS?

The Online UPS is a type of UPS in which delivers power through the battery to the load as the batteries in it are directly connected to the inverter. This eliminates the need for a power switch in case of an online UPS.

Q. What is difference between online and offline inverter?

Lower Cost offline UPS generally, when on inverter/battery backup, provide a square/pseudo sine wave output waveform. Online UPS takes the incoming AC mains supply and converts it to DC which feeds the battery and the load via the inverter.
