UPS are essential to protect the computer and other electronic devices from burning out when a power outage happens suddenly. If you run out of electricity. You will be able to use your computer for a limited period because of the equipment’s electrical energy storage capacity.

In electricity surges, the UPS prevents computers from suffering any damage, as it also works as a power stabilizer. Each model has a specific power ranging from 500 VA to 3200 VA.

How to choose the best UPS and what models there are

UPSs are electronic devices that are capable of protecting your equipment in the event of a power outage. They are equipped with internal batteries. And allow the devices connected to them to continue working for a certain period of time. In addition, there are models capable of stabilizing the voltage, monitoring the energy consumption of the equipment, among other functions.

What UPS models are there?

Basically, no breaks can be divided into two large groups: Offline and Online, within these groups there are subdivisions such as interactive line and double conversion. In addition, they can still be separated by the type of wave they emit: sine, sine (approximate sine), square.

The difference between online and offline UPS is in the way UPS behaves during a power outage. The offline UPS starts powering the equipment from the moment there is a power outage. The time for this activation to occur lasts milliseconds, normally supplied by the computer’s source. However, even this tiny amount of time can be detrimental to more sensitive equipment.

Online no breaks are always powering the equipment from batteries, so when there is a power outage, there is no activation time for the batteries. That is, the energy passes to the break and the break feeds the equipment directly from the battery. That way, the battery is always charging and distributing power. It is the ideal model for more sensitive equipment that cannot suffer from changes in energy. 

Stand-By (Off-Line):

Offline models are the simplest on the market, offering efficiency and low cost. Because they are more affordable, they are the most seen in homes and offices. They have a very short battery activation time that is not enough to make computers restart or shut down, which makes them excellent for computers, televisions, monitors, routers, among others. For more sensitive equipment such as servers and hospital equipment, they are not indicated. In addition, offline UPSs do not function as a voltage stabilizer.

Interactive (Off-Line):

Interactive models are intermediate between offline and online models. The biggest difference between them is the ability to do voltage stabilization. That is, if there is an overload in the outlet, the UPS decreases the voltage, and increases the voltage if there is Undervoltage. As it is a type of offline UPS, it also has an interval between power failure and battery activation and is also not suitable for sensitive equipment. Some interactive no breaks also come with a USB input that allows you to control energy consumption, voltage and even program the equipment connected to it to turn off in case of a power outage and turn it back on when the power comes back on. 

Double Conversion (Online):

Online UPS are the most expensive and offer the most advanced technology. All the energy that passes to the equipment passes through the UPS first. This makes the energy always constant and without variations. As the UPS is always supplying power, there is no delay between battery activation and power outages. For this reason, they are excellent for more sensitive equipment such as servers, devices used in hospitals, banks, among others.

They also come with a USB port to monitor power consumption, the voltage at outlets, as well as program computers to automatically turn off and on during and after power surges or power outages. 

APC BZ1200BI-BR 1200VA

This UPS model has a technology capable of protecting your computer and other electronic devices from power surges, short circuits, Undervoltage, overvoltage, and overload. If the electrical power changes, the audible alarms feature will notify the user. The automatic self-test guarantees automatic detection. If the battery needs to be changed.

You will also be able to take advantage of the automatic regulation of high and low voltages to a safer level without the need to use battery mode. The fault detector has an LED indicator to inform you of wiring problems present in the electrical installation that can cause damage. Battery management ensures long battery life due to precision intelligent charging.

What power should I choose for my UPS?

Each UPS model has a maximum power to be respected. The more items connected to it. The shorter the autonomy time that the equipment will be on without power. Before choosing the UPS. It is necessary to analyze all the equipment that will be connected to it, calculate the consumption, and see if the UPS meets the needs.

Every electronic device has somewhere an indication telling the total power consumption. Which is usually expressed in Watt (W). But sometimes it is shown as Volt-Ampere (VA). Check all consumption powers and add them up, so you will know exactly how much autonomy the battery will offer:

How to choose the best UPS?

We always start by thinking about which products we want to connect to the UPS. So that, from there, we can find the Total Power (W or VA). And then, think about which type of UPS (Online or offline) will be better. Based on the products that will be connected. Two points are fundamental in choosing the best model. Such as the input and output voltages and the UPS format itself. Which can be Rack or Tower. From this, it is possible to identify the best option based on the settings and also according to the needs of each user.

The process of purchasing a UPS may seem to be something extremely rigorous and detailed. But it is the best alternative to avoid future problems in the network, equipment and guarantee security when necessary.
