UPS uninterruptible power supplies - key information

What is a UPS and how does it work?

A UPS (Uninterruptible Power Supply) is a device that provides an uninterrupted supply of electricity in the event of a mains power failure. It acts as a backup power source, automatically switching to battery power when the power goes out. This allows a computer, server, or other connected devices to safely continue working or be properly shut down without risk of damage or data loss.

How does a UPS back up power?

A UPS sustains power by switching to power from an internal battery when a mains power failure is detected. The battery in the UPS is charged during normal operation, allowing it to respond immediately in the event of a power outage. The UPS's backup time depends on its power and the load of the connected devices.

Why choose a UPS for your computer and server?

Selecting the right UPS for your computer and server is crucial to prevent data loss and equipment damage due to unexpected power failures. A UPS provides power back-up and protection against power disturbances, which is especially important for IT equipment. This allows us to avoid interruptions and increase data security.

How to choose the right UPS for your home or business?

Buying a UPS is an investment in security and peace of mind. How to choose a model that will provide a stable source of power both at home and in a small office? A UPS with too little power or with a battery of insufficient capacity will not provide power to IT devices and home electronics in the event of a sudden power outage from the grid. What kind of UPS to choose?

What to pay attention to when choosing a UPS?

When choosing a UPS, it is worth paying attention to several key parameters:

- Rated power of the UPS: It should match the total power consumption of the connected devices expressed in Watts.

- The power backup time: Determines how long the UPS can sustain power in the event of a power outage.

- Number and type of sockets: Should suit our needs and the type of devices to be plugged in. Note that the Unischuko plug will fit both French (type E) and Schuko (type F) outlets.

- Topology of the power supply: Line-interactive UPS or online UPS, depending on the application.

Which UPS is suitable for the home?

For the home, it is advisable to choose a UPS that will provide sufficient power backup time for basic devices such as a computer, router or TV. A 500-1000 VA model should be sufficient for most home applications. It is also important that the power supply has a surge protection function to protect equipment from sudden power surges.

How to choose a UPS for the office? Power backup devices for professional electrical equipment.

In an office, where power backup and protection of IT equipment are crucial, it is worth investing in more advanced UPS models with higher power, such as 1500-3000 VA. It is important that the power supply has a sufficient number of outlets and the ability to be managed via the network or software. This allows you to monitor the status of the power supply and batteries from your computer, making management and maintenance easier.

Installation and maintenance of UPSs

How to connect a UPS?

Connecting a UPS is relatively simple. All you need to do is plug it into a power outlet, and then plug the devices you want to protect into the power supply. It is important not to overload the UPS and not to connect devices with higher power consumption than the maximum rated power of the power supply expressed in Watts.

How to check the operating time of the UPS?

You can check the operating time of a UPS by testing it under controlled conditions. Disconnect the mains power supply and observe how long the UPS maintains power to connected devices. It's also a good idea to check the battery's condition regularly to make sure it's fully charged and ready to operate in case of an emergency.

How to take care of the battery in a UPS?

In order for the battery in your UPS to work properly, there are a few rules to follow:

- NOTE: Discharge and recharge the battery(s) every 3 months to ensure their full life. Failure to do so will shorten the life of the battery!

- Test the UPS regularly to make sure the battery is in good condition.

- Avoid completely discharging the battery, which may shorten its life.

- Keep the UPS in proper temperature conditions to prevent the battery from overheating.

Differences between different types of UPS.

What is the difference between a line-interactive UPS and an online UPS?

Line-interactive UPSs work by automatically switching to battery operation when there is a power outage on the grid. They have a built-in voltage stabilizer (AVR) that protects against mains disturbances. Online UPS, on the other hand, provide continuous battery power, which guarantees the highest quality and stability of current, eliminating any interference with the electrical grid.

What are the characteristics of rack-type UPSs?

Rack UPSs are designed for installation in server racks and data centers. They are characterized by compact design and high efficiency. Thanks to their rack mounting capability, they take up less space and allow easy management of IT infrastructure.

What is the importance of full sine wave in UPS?

Full sine wave in UPSs involves generating a pure sine wave while running on a battery. This makes the injected current more stable and the UPS operation safe for connected devices, which is especially important for sensitive electronic equipment such as computers and servers. A good server UPS will protect against the failure of a website, server or online service, allowing you to switch to alternative backup power.

Which UPS should you choose to protect your computer and other devices from failure?
