When and why you would need a UPS device

Read this article to see how you can protect your home appliances, especially if you live in an area where you face certain problems related to the supply of electricity, such as fluctuations or interruptions.

The investment in a UPS will be amortized quite quickly, especially if you live in areas where power outages are frequent and there are large fluctuations in the network, which can damage the appliances you own.

What is a UPS?

A UPS is an uninterruptible power supply, and the acronym comes from its English name Uninterrupted Power Supply. It offers backup power and solves the problems you may have with the mains supply. Thus, the devices connected to the UPS will be protected from current fluctuations and give you time to perform various operations.

You can power various appliances

If it is a power failure, the UPS will provide you with a period of their operation, which may be different depending on the type of device. This is not a generator, so the charging time is limited depending on the battery capacity.

In case the interruption is short-lived, it can support the devices in working order, and if it lasts a little longer, it gives you the necessary interval to save the data on the computer and to turn off the device.

Provides better food quality

In case the voltage fluctuations are frequent in the electricity supply network, the electrical circuits from the household appliances being very sensitive can easily fail.

A UPS works similarly to a voltage stabilizer and will protect the connected equipment, filtering the electric current and releasing a flow in normal operating parameters. It can be of real use for the protection of the thermal power plant which is an important investment and is sensitive to fluctuations, to wood thermal power plants to not stop the heat supply in case of short outages, for the protection of air conditioners, refrigerators, refrigerators etc., which are large consumers.

Provides protection in case of overvoltage

The mains power supply is aging in many areas and there are shocks that can severely affect home appliances. The vast majority of UPSs have overvoltage protection, but may differ from one model to another, having a maximum absorption capacity. Usually this is specified in the technical book of the product and is measured in Joules.

If the mains voltage is higher than the UPS's suction power, it may let the shock through, which may damage the equipment or enter a protective mode, interrupting power. If you often face such a problem, be sure to purchase a model with as much surge protection as possible.

Automatically turns off connected appliances

If the power supply to the mains is interrupted, the UPS automatically shuts off all devices connected to it, so that they can be protected from shocks that may occur when they run out.

Because it can only provide a limited amount of time to power, as much as the battery capacity, when the power returns, the appliances, if not turned off, can be subjected to shocks that can burn them.

How can you determine the quality of the electricity supplied to the network?

Even if you do not have power outages in the area, you need to see what the quality of the current supplied is. In Europe the alternating current must ideally have a voltage of 230 V and a frequency of 50 Hz, in the USA it is 110V and 60 Hz, but it is considered normal from the supplier's point of view, a variation of + – 10%.

The fluctuations in the network can be seen with the naked eye, if they are large causing the bulb to flash, or it can be measured with a multimeter for smaller variations. It is very expensive to buy UPS for each outlet, as it would be an ideal way, but you can protect your expensive equipment that is more sensitive such as TV, computer, but also central heating, large appliances, etc.

How do you choose a UPS compatible with your needs?

In order to choose the best UPS for the boiler ( a comparative list here) or other appliances in the house you need to know what types are on the market.

From the point of view of the technologies used, there are several types of UPS:

Off-line: the simplest variants, being also the most convenient at the price. These have the role of interposing between the equipment and the power source, and in case of detecting a supply failure, it comes into operation and passes on the battery. They have no effect on its quality. It is recommended for areas where there are no problems with network fluctuations and you just want protection in case the power goes out.

Line-interactive: there are models dedicated especially for household appliances, with a decent purchase price, overvoltage protection, good current filtering to bring it into normal operating parameters. It only takes a few milliseconds to switch on the battery in the event of a power failure.

On-line: they are addressed especially to the industrial field, where you need a superior quality of current. The input current is converted twice to the output, being cleaned of all fluctuations, and offering an alternating output current in ideal parameters, for the proper functioning of the sensitive equipment. The switching time is 0, which also helps a lot in the IT field.

Hybrid: which behaves like an offline UPS when it is in standby and switches to online mode when a problem is detected at the power source.

You definitely need a UPS that protects your expensive home appliances, and that allows you to enjoy more of the investments you make. There is a wide range of such devices on the market, and you can do your shopping online, from online specialty stores, where you will find other product information to help you choose.
