Line Interactive UPS System, Provides an Effective Way to Continue the Workflow

In today’s upgrowing and busy world when everything is going digital with modern technologies, power fluctuation may lead to a disaster especially for the server rooms, hospitals, industries like power plants, etc, and it can harm the whole system. In this situation, people should be prepared for power surges. An uninterruptible power supply device (UPS system) can keep the situation under control by providing a smooth and uninterruptible power source and protecting the load against loss of coverage when the power is unavailable. 

There are three types of UPS systems are available-
                                            1. Online UPS system
                                            2. Standby or Offline UPS system
                                            3. Line Interactive UPS system

What is a UPS System?

UPS system is also known as battery backup. An uninterruptible power supply is a device that provides smooth backup power to the equipment in the event of a power outage or power fluctuations. UPS allows for safe shutdown of the connected load and save valuable data as well as the load from power problems including, fluctuations, power outage, brownouts, spikes, using a battery, known as a secondary power source. UPS systems act as a buffer between the main power source and computers.
Usually, there are three essential functions of a UPS system-

Sometimes spike in voltages and overcurrent can damage the hardware. UPS devices avoid damages by continuously regulating the input power. 
Avoids downtime and takes the guarantee of the availability of networks. 
UPS system ensures the safety of data by avoiding data loss and damage. 

Working Method of a Line Interactive UPS

A line-interactive UPS redirects the DC current direction of the battery from the normal charging mode in order to supply uninterruptible power to the load and also maintains the inverter in line. Voltage Independent is an allies name of line interactive uninterruptible power supply system. It can respond to high and low voltage conditions with its automatic voltage regulation technology and provides power conditioning. Line-interactive UPS systems are usually available with a capacity between 750 VA and 5 KVA and are the most common one used for small businesses among all UPS systems. 

Line interactive UPS contains an EMI (electromagnetic interference) filter, also known as a surge suppressor that usually controls the surge of the input AC current. The automatic voltage regulator (AVR), placed after EMI, percepts the input volt and supply it to the inverter that plays a dual role. It converts and steps down the AC current to DC through a transformer and charges the battery when the main AC is available. In the event of a power outage or voltage fluctuation, the battery immediately starts to discharge and again provides the DC current to the inverter. The inverter converts the DC to AC and passed it through a filter in order to remove the variation and supply it to the equipment, to avoid any type of disturbance to the work process. 

Benefits a Line Interactive UPS Provides

Line interactive UPS performs better as the main AC is available, as compared to the Offline UPS system. High reliability, high efficiency, and safety make a line interactive UPS best for small businesses. It utilizes lower electricity and a reasonable power conditioning to the load. Being simple in design line interactive UPS has a lower component count. It is budget-friendly, works with fewer batteries, and provides protection against power failure, power sag, under and over voltage, power surge, etc. The AVR corrects the voltage when it crosses a pre-specified low or high value without switching to the battery.
Why Line Interactive UPS is Better and Where It Can Be Used?

An offline UPS generally provides a customary level of power protection to the load, at the same time line interactive UPS dispenses a better and intermediate level of power protection. A line interactive UPS ensures the safety of power-sensitive equipment by taking 2 to 4 milliseconds to transfer the power while an offline UPS takes at least 2 to 10 milliseconds, and the power range of LI UPS is 0.5 to 5 KVA.

During a short-term power outage or voltage fluctuations, A line interactive UPS maintains the performance and allows the load to shut down safely without any damage to the system or data.  
Usually, An offline UPS can be used in EPABX, scanners, emergency power supply, personal computers, households, but a line interactive UPS usually is used in small businesses, offices, departmental servers, medium enterprises, and areas with unstable voltage.
