A suitably best UPS comes out to be a crucial purchase for any business that relies on networks, servers or PCs and other gadgets being on power round the clock.

For many businesses (small or large), if there’s a power cut – even a brief one – loss of power can be disastrous. Power loss can cause the files as well as the servers to become unreachable – or even worse, distorted – by an abrupt shutdown.

For such catastrophic conditions that can occur, a UPS can be installed to avert the calamity commanding when the power is cut, by seamlessly switching to battery power to keep powering your electrical until either the main power is restored, or you’re able to securely shut down your gadget.

Downtime induced by power outages, even if it’s very brief, can be annoying for anyone, but at the same time can be back-breaking for a business or organization financially.

“Every year, business organizations lead to lose fortune just because of the interim downtime caused by power distortions.”

And because of limited ability to generate revenue during downtime, small to medium-sized businesses are likely to be at higher financial risk.

However, these power disruptions can easily be prevented by a UPS, especially using a UPS with auto shutdown. A UPS with auto shutdown feature allows you to sophisticatedly shut down your electrical during power outage. It’s a hands-down device protection strategy that not just saves your

  • IT infrastructures
  • desktop PC
  • office/home network
  • media server

By providing emergency power through battery, that further enables you in safely saving your data/files and power down your device appropriately.

Does an UPS is same as an Inverter?

  • No, do not confuse UPS with inverter. Both of them are completely different and have so much in variation.
  • UPS is an electrical power solution device that supplies power to the required load, when the main power supply fails, whereas an inverter is the one which converts the direct current (DC) into alternating current (AC).
  • The main function of an UPS is to work as the flywheel storage systems and in terms of an inverter to convert AC power to DC power.
  • The UPS consists of an inverter and controller circuit for the storage and flow of power during power outages and the inverter contains only the battery for the power backup.
  • UPS can also protect against the voltage fluctuations, but an inverter cannot. Hence the voltage to the load from the inverter can be varied.
  • The battery backup period of an UPS is about 10 – 20 minutes and the instant switching action takes place during the power outages, whereas the backup period of an inverter is about 3 – 6 hours and it takes time for the switching action.
  • UPS is more affordable than an inverter.

Which is better UPS or Inverter?

Bottom Line: In comparison, the UPS monitor system is more efficient than an inverter and provides the electric backup needed to the appliances without delay and variation. While on contrary, an inverter is a channel between the battery and the primary power supply. The battery assists in preserving the energy storage and converts the store AC into DC during the power outages while rendering power to the electrical inverter.

What are the common problems in the Electrical power lines?

What are the common problems in the electrical power lines
Image Source : signs

Uninterrupted Power Supply (UPS) plays an ultimate role whenever the power shut downs takes place. If you want to know the whole concept of an UPS, there you should get to know the important factors, on which the problems tend to occur and the reason why they are occurring. Since we are facing a number of different power problems that tend to occur in the power lines safety, let us explain you the most common and important terms in detail here.

When the voltage sag occurs?

Decrease in the voltage – Whenever the problem of short circuit, overload or heavy load start-ups occur, there is a small period of reduction in the root mean square (rms) voltage. Hence voltage sag is occurred when the rms voltage reduces between 10 and 90 percent of nominal voltage range for one-half cycle to one cycle minute. Generally, the normal sag duration is from 0.5 cycle to a few seconds. Voltage sag is just an opposite condition of a voltage swell (voltage swell – increase in voltage).

Why surges are problem in electrical lines?

Surges are just an opposite to sag which is an increase in voltage above the normal voltage level. It may damage the electrical circuits of the device. Generally, it is being caused by lightning.

What voltage spikes?

Spikes are just a fast moving energy that occurs only a fraction of seconds in the electrical space in terms of electrical transients in voltage is called as voltage spikes. Voltage spikes can be referred to be known as the sustained over voltage.

How the blackout arises?

The scenario where the power shut down takes place for a momentary period of time to days, and then it is called power blackouts. Blackouts takes place during the condition of natural disasters like bad weather conditions, cyclones, electrical accidents, power failures in the station itself.

What are brownouts?

A sudden drop in voltage level for a certain period of time, whether it is planned or not, is meant to be brownout in terms of electrical power line problems. In case of an emergency need, it may be done by the electrical power stations to minimize the cause of a total sudden blackout.

What is electrical Transients and how it is minimized?

When there is a sudden change in the state of the normal flow of electrical signal, then it is said to be known as a transients otherwise known as oscillations which occurs only a short duration of time. Change in the electrical signal will create an unstable condition in the level of voltages. It results in the oscillation of the electrical power lines. Reasons for Electrical Transients – lightning strikes, power shut-down, tripping of circuit breakers, short circuits, heavy load powers, power problems in the main supply, etc.,

Importance of Harmonic distortions

Normally, harmonics is referred to as the frequency of the signal of a wave that is an integer multiple of the fundamental frequency. When there is an alteration (deviations in the wave form) in the harmonics, there occurs a harmonic distortion. It is measured in terms of Total Harmonic Distortion (THD).

“THD is the ratio of Sum of the Powers of all the Harmonic Components to the Power of the Fundamental Frequency”

(THD = Sum of the Powers of all the Harmonic Components / Power of the Frequent Frequency)

Why electrical noise should be avoided?

When there is an occurrence of an unusual disturbance in the electrical signal, then an unwanted sound is being produced by the electrical devices. It is said to be known as the electrical noise. It is considered to be known as the error or undesired disturbances in the communication systems.

When the frequency variation occurs?

The frequency of the main power supply has to be maintained in an appropriate level. It occurs while the load is supplied power with generator.

What are the alternate power supply solutions?

Sure, there are various alternative power supply solutions that keep your life going on brightly, shiningly.

Below are the alternate power supplies:-

  • Uninterruptible Power Supply (UPS)
  • Inverter (DC Current Charge)
  • DG ( Generator Sets)
  • Voltage Stabilizer
  • Solar Power (Sunlight Charge)

Out of these solutions, the one that’s picking up the frenzy due to its affordable cost and compactness is the UPS (Uninterruptible Power Supply).

What is an UPS (Uninterruptible Power Supply)?

UPS— the abbreviated form of (Uninterruptible Power Supply) refers to an electronic device. As the name suggests, the UPS unit renders unceasing battery backup when the electrical power fails to an impermissible voltage volume.

A UPS monitors offers:-

  • Guaranteed power protection for connected devices
  • Immediate provision of clean battery back-up when power is interrupted,
  • Surge protection for plugged-in, sensitive devices in cases of frequent fluctuations
  • And most importantly your self-satisfaction

It depicts that not all UPS systems are produced equal or are created in a manner to provide adequate backup to different gadgets.

“Before having to buy a particular UPS unit, it’s crucial acquainting yourself with the various types of UPS products available and how they work.”

UPS differs in size from products created to protect a standalone computer system without a video monitor (about 200 VA rating) to bigger units powering whole of the data centres (>1MVA), premises (>300kVA), or production processes.

The size and configuration of a UPS identifies how long the system will supply power.

This means

  • Small UPS systems possess the power to provide power only for a few minutes; as much as necessary to power down a computer system in a systematic way
  • Larger UPS systems have as much as necessary battery to provide power for several hours
  • in goal-centric datacentres, UPS units are used to provide power for only a few minutes until electrical generators gain control

A UPS system is different from an emergency or supplementary power system or standby generator in that it will provide immediate or pretty quick protection from input power disturbances with the aid of one or more linked batteries and integrated electronic connections for low power users, and or by source of generators and flywheels for high power users.

The on-battery runtime of most UPS is comparatively short duration of 5–15 minutes being standard for smaller systems – but enough to sanction time to bring a supplementary power source online, or to appropriately shut down the safeguarded device.

Wherever the UPS system is used/applicable for?

Above we have listed the best UPS in general. Following are the purposes of UPS for specific applications and their best brands and models of UPS listed following the links. Uninterruptible Power Supply becomes an essential for both the commercial and industrial purposes as well. To avoid the unwanted and an unexpected power shutdowns of the electrical devices we are in need to of an UPS to be utilized.

How does an UPS system work?

The UPS device works by an electromagnetic mechanism of setting up to warn file servers to shut down in a systematic way when an outage happens, and the batteries are running out.Many of us who are engaged with emergency back-up power are usually been told to manage a number of complex systems that need particular attentiveness to parts, productivity and power Outage point

All said and told, there is been a lot to deal with, and it always helps to have some guidance for understanding the basics of these systems. While not just restricted to safeguard any specific kind of electrical device, a UPS is commonly incorporated to protect

  • Data centres
  • Wireless Networks (routers, modems)
  • Servers
  • Computers & Peripherals
  • Gaming Consoles
  • Mobile Devices
  • home appliances
  • business or telecommunication equipment
  • electrical equipment

where an unforeseen power disruption could cause seriously devastating injuries to business operations and/or data loss and of course make you unnecessarily sad for having to get the business mislay.

Different types of ups designs that work differently

Types of UPS design

In general, there are 3 classifications of modern UPS systems that are as follows:-

  • Standby/Off-Line
  • On-Line
  • Line Interactive

Now which type of UPS system is well-suited for your device will depend upon UPS Sizing calculation.

Thereby lets first get an idea how the different types of UPS vary from each other and how can they help your device to keep the working mode on in absence of electricity.

Standby/Offline UPS designLine interactive UPSOn-Line / Double Conversion UPS:

Standby/Offline UPS design

Ideal Application: Small home appliances

Also known as a break/fix type of UPS, with the standby/offline UPS, the load is straightaway powered by the input power while the backup power circuitry is only solicited when there is a failure in the utility power. Generally UPS under the electrical power of 1 kVA are of the standby/offline or the line-interactive variety which are generally less expensive.

It provides only the basic features of:

  • Battery Back-up
  • Surge Protection
  • isolation and disturbance depletion
  • converts AC to DC power that’s compatible with battery’s voltage and attributes

The Standby/Offline UPS (SPS) system turns on its internal DC-AC inverter circuitry when the incoming utility voltage drops down below an accepted level.

Powered from an internal storage battery, the SPS then mechanically switches the linked device on to its DC-AC inverter output with the maximum switch over time of 25 milliseconds. The switch over time directly depends on the time taken by the SPS to recognize the lost utility voltage.


  • Good Efficiency with the battery that’s not frequently used & provide short-term source of electrical power
  • maintained battery voltage with a rectifier/charger
  • Automatic switch to transfer load between utility and the inverter with least disturbance


  • Limited protection against spike and sag
  • Not always a reliable output
  • Takes a transfer time when main falls

Largely if you ask, the UPS is designed dependent on size of UPS connected load, sensitivity of the connected device to voltage fluctuations or specification to cover certain ranges of device, without any apparent drench or debilitation to that device.

Line interactive UPS

Ideal Application: Best for premises where you are not to safeguard mission critical devices and the utility power is passably clean. These can even be used for a smaller office.

Use: This type of UPS critically maintains the inverter in line and curves back the battery’s DC current track from the usual normal charging mode to supplying current when there is power loss.


  • Line-interactive UPS design has the capacity to tolerate continual over voltage surges and under voltage brownouts without even stuffing down the limited reserve battery power.
  • Changeable auto transformer tap
  • Usually Rated between 0.5 KVA and 5 KVA provide the main AC line to be clear from any transients and Trans pierces.
  • Have the superiority of low cost, compactness, and better output since it takes advantage of components already included
  • Efficiency of as much greater than as 97%,


  • Does not offer any voltage regulation during normal mode of operation.
  • Changing the auto transformer tap can induce a short, indeed very short output power disruption, so the UPS may make a canary critter for a moment, since shortly switches to the battery earlier than changing the selected power tap.

On-Line / Double Conversion UPS

Incorporating a “double conversion” strategy of undertaking AC input, amending to DC for transiting across the rechargeable battery, then inverting back to 120V/240V AC for powering the protected instruments.

Ideal Application:

  • arenas where electrical separation is required for appliances that are very sensitive to power fluctuations
  • common consumer equipment, supplying 500 watts or less
  • for massive installations of 10 kW or above

The basic technology of the online UPS monitor is similar to standby or Line-Interactive UPS, though it’s called Double-Conversion because of the rectifier directly driving the inverter to run continuously, even when charged from normal AC current.


  • During power loss, the rectifier just withdraws from the circuit and the batteries keep the power stable, thus preventing boiling off the electrolyte and overheating of the batteries
  • Highly reliable for protection against spike and sags, especially for sensitive electronic equipment.
  • provides long run times in a small space with the emergence of modern fuel cell UPS
  • Provides power with zero transfer time to the connected device, thereby most suitable for installations with mission critical devices, or in establishments with poor power conditions.
  • internal static bypass, that allows keeping critical loads online even if UPS has a major failure


  • Usually more expensive but may be inescapable during piercing power environment such as in factory settings, for devices with larger loads like data centres, or when functions from supplemented-run backup generator is required
  • costs much more than standby or Line-Interactive UPS
  • Overall declined efficiency since inverter always remains ON
  • More heat on UPS

Q. What are the common electrical power problems occur?

A. Whenever the sag, surges, blackouts, brownouts, short circuits, wrong wirings, manual fault occurs, spike voltages or currents are some of the common electrical power problems that occurs in the power lines.

Q. How much backup time will I get for using the loads of 1 TV & set top box together?

A. While using the loads with apc be 700 y – 420 Watts, the inverter ups will provide the backup time of about approximately 25 – 35 minutes.
