From offline basic protection to dual conversion medical grade protection, different models can cope with power outages, surges, and voltage fluctuations, protect equipment life, and maintain continuous productivity in crises - this is the invisible armor for modern electronic devices to survive 24/7.

For many of us who rely on computers for work, study, business, and financial activities, power outages can cause major problems. We may lose data, miss important transactions, and unintentionally withdraw from important meetings. It may even damage the computer hardware, further hindering us from completing the task.

As a solution, many people are starting to purchase uninterruptible power supplies, also known as uninterruptible power supplies. These devices have been proven to be highly effective, making them a standard configuration for many businesses and institutions. But what exactly is an Uninterruptible Power Supply? How does it work? Let's take a look!

A、 What is Uninterruptible Power Supply:

An Uninterruptible Power Supply is a device that maintains power supply during power outages, such as voltage drops and power outages. An Uninterruptible Power Supply is essentially like a portable power source that provides power to a computer, but it has an automatic transfer switch (ATS) that can immediately provide power in the event of a power outage.

Uninterruptible power supplies are commonly used in commercial facilities, hospitals, schools, etc. As more and more people recognize the benefits of uninterruptible power supplies, their use in homes has become increasingly common.

B、 The benefits of having an Uninterruptible Power Supply:

Equipping an Uninterruptible Power Supply next to a computer is a good way to ensure that it can continue to work even in the event of a power outage. In addition to providing power during power outages, uninterruptible power supplies have the following other advantages that make them the best backup power source:

1. Continuity: Although there are other ways to power a computer during a power outage, an Uninterruptible Power Supply uses a special switch to instantly provide power, and your computer will not notice the switch from the main power source to the backup power source. This prevents your computer from shutting down immediately, allowing you to work continuously without having to start the computer and load applications.

2. Data loss prevention: Uninterrupted power supply provides uninterrupted power. In the event of a power outage, the Uninterruptible Power Supply immediately provides power to the computer and notifies you when the backup power supply is activated. This provides you with time to save data or continue working until the battery runs out.

3. Hardware protection: Depending on the type of Uninterruptible Power Supply you purchase, you can expect varying degrees of protection from various power disturbances. This ensures that the precision components in your computer always operate within their designed range.

C、 How does an Uninterruptible Power Supply work:

An Uninterruptible Power Supply is essentially a short-term battery power source equipped with a quick switch to provide instant power. The basic components of an Uninterruptible Power Supply include a battery, battery charger, inverter, and automatic transfer switch (ATS).

To set up the system, you only need to plug your computer into an Uninterruptible Power Supply and power it through a wall socket or convenience outlet.

During normal operation (when power is available), the Uninterruptible Power Supply passively charges the battery through a battery charger while supplying power to the computer. When a power outage occurs, the automatic transfer switch (ATS) automatically cuts off the household power supply and switches to the backup power supply from the battery and inverter.

Depending on the type of Uninterruptible Power Supply, there may be other modes to ensure that your computer is not powered off.

D、 Common Uninterruptible Power Supply configurations:

There is considerable power interference that may damage your computer or other sensitive electronic devices. These interferences are classified as line noise interference, undervoltage, overvoltage, voltage drop, voltage surge, and power outage.

To cope with these interferences, manufacturers have started to introduce different types of uninterruptible power supplies with varying degrees of protection. These Uninterruptible Power Supply configurations include offline/backup uninterruptible power supplies, line interactive uninterruptible power supplies, and online/dual conversion uninterruptible power supplies.

To understand which type of Uninterruptible Power Supply is more suitable for your usage scenario, let's talk about each Uninterruptible Power Supply configuration, its advantages, and its working principle. Let's start with the most common offline or backup Uninterruptible Power Supply:

1. Offline or backup Uninterruptible Power Supply:

Offline or backup Uninterruptible Power Supply is the most common type of Uninterruptible Power Supply on the market. It protects equipment from power outages by configuring standard battery chargers, batteries, automatic transfer switches (ATS), and inverters.

Although it only provides the most basic protection, its cost-effectiveness in preventing data loss and providing sustained short-term power makes it ubiquitous in households. Since this type of Uninterruptible Power Supply only provides minimal protection, you should consider purchasing a surge protector.

2. Line Interactive Uninterruptible Power Supply System:

Line interactive uninterruptible power supplies provide greater protection as they eliminate the impact of power outages, power surges, power drops, overvoltage, and undervoltage on your electronic devices. This type of Uninterruptible Power Supply is typically used in high expansion businesses, but it is also becoming increasingly popular in ordinary households.

The online interactive Uninterruptible Power Supply consists of the same components as the offline Uninterruptible Power Supply, but an additional step-up and step-down transformer is added. This type of transformer balances significant power attenuation before the electrical energy reaches the equipment or device.

3. Online or dual conversion Uninterruptible Power Supply system (Uninterruptible Power Supply):

Online or dual conversion uninterruptible power supplies are specifically reserved for sensitive equipment in critical mission applications, such as medical devices, online banking systems, and emergency communication equipment. This type of Uninterruptible Power Supply is not suitable for household use because it is usually large in size, heavy in weight, and has high purchase and maintenance costs.

The characteristic of an online Uninterruptible Power Supply is that it mainly consists of a full bridge rectifier, a battery charger, and an inverter. The design concept of this Uninterruptible Power Supply is to supply power to equipment through batteries installed inside the Uninterruptible Power Supply, without the need for direct connection to the grid. This basically provides a sandbox environment for any device powered by an online Uninterruptible Power Supply, effectively protecting the device from all power interference, including line noise interference.

E、 What is the difference between Uninterruptible Power Supply and programmable power supply system (PPS):

In addition to Uninterruptible Power Supply, you can also choose another popular backup power supply, even portable power station (PPS). PPS is similar to Uninterruptible Power Supply, but lacks ATS, so it cannot immediately provide power to your equipment. However, PPS also has its own advantages, such as higher wattage output, portability, and larger batteries.

If you are looking for a backup power source for emergency situations and weekend camping trips, a portable power supply (PPS) is a good choice worth considering. But if you particularly need to protect your data, work progress, and device hardware from power interference, then an Uninterruptible Power Supply should be the best companion for your device.

Although both provide backup power, PPS and Uninterruptible Power Supply are different devices used for different purposes. Having both backup systems is always the best choice, as uninterruptible power supplies provide uninterrupted power while PPS provides more durable power.

F、 Uninterruptible Power Supply protects your computer 24/7:

Uninterruptible Power Supply is an essential device for everyone who owns a desktop computer. It not only ensures uninterrupted power supply, but also protects your equipment from harmful power interference.

But please remember that an Uninterruptible Power Supply is not a continuous power supply (PPS), it must be connected 24/7 to a wall outlet to ensure your computer is protected 24/7. Although more expensive, if you are concerned about the lifespan of your equipment, it is best to invest more in online uninterruptible power supplies rather than offline ones.
