How To Choose Uninterruptible Power Supply

It is not difficult to choose a UPS system, but there are still some details to pay attention to in order to choose the device that suits your needs. Next, let's take a look at three key points to see how to choose the UPS device that best suits your needs.

1. Choose the right power supply mode: understand the difference and avoid waste

UPS power supply modes are mainly divided into three types: offline, online interactive and online. These three types of devices are designed for different scenarios, so don't choose them at will, but decide according to actual needs.

Offline UPS

If you just need to ensure that a few ordinary computers or home routers can run for a period of time when the power is off, then an offline UPS is a good choice. Its working principle is that it does not participate in power supply at ordinary times, and only starts the battery when the power is off. Although there is a delay of several milliseconds when switching, it is enough to cope with daily household needs.

Applicable scenarios: Home users with limited budgets, suitable for those devices that do not require high power stability.

Advantages: Affordable price, energy saving and power saving.

Disadvantages: Delayed switching is not suitable for devices that require strict power continuity.

Online interactive UPS

This type is more suitable for small businesses. It can not only switch to battery power when power is off, but also automatically adjust when the voltage is unstable to ensure that the equipment will not be damaged by voltage fluctuations.

Applicable scenarios: offices, small servers, network equipment, etc.

Advantages: It strikes a balance between performance and cost, and can not only cope with power outages, but also handle voltage fluctuations.

Disadvantages: The price is slightly higher than the offline type, but the performance is stronger.

Online UPS:

For scenarios such as data centers and hospitals that require continuous power support, online UPS is the most suitable choice. It is powered directly from the battery without switching, and there will be no interruption when the power is off, ensuring that the equipment is always in power protection.

Applicable scenarios: Enterprises and key equipment with extremely high power requirements, such as data centers, important servers, etc.

Advantages: The most stable power protection, suitable for critical applications.

Disadvantages: High power consumption and high cost, not suitable for general daily use.

2. Determine the capacity of the UPS: While protecting the equipment, you must also prepare for the future

The choice of capacity is often overlooked, but it is crucial to the performance of the UPS. The capacity of the UPS is generally expressed in VA (volt-ampere), which determines the load it can support. When choosing, you should consider your current equipment needs and leave some margin for possible future expansion.

Home and small office equipment: If you only need to provide backup power for a few computers and network equipment, 500-1000VA is enough. Generally speaking, home users do not need to pursue too high a capacity.

Small and medium-sized enterprises: If your business has key equipment such as servers and switches, then a 1000-2000VA UPS would be a more suitable choice to ensure that the equipment has sufficient power support during a power outage.

Data centers or large-scale equipment: In this scenario, you may need a 3000VA or even higher UPS to cope with complex power needs. Here you should not only consider the existing equipment, but also reserve space for future equipment expansion.

3. Look at additional features: details determine the experience, don't ignore these small features

In terms of functions, in addition to the power supply method and capacity, the additional functions of the UPS also determine the quality of the user experience. Here are some features worth paying attention to:

Automatic voltage regulation (AVR): This is a key function for handling voltage fluctuations, which can protect equipment when the voltage is too high or too low. For devices that need to be used for a long time, this function can extend the service life of the device.

Display and status monitoring: A clear display can help you understand the status of the UPS in real time, monitor key information such as battery power and load at any time, and prevent the device from losing protection without your knowledge.

Remote monitoring and management function: For large companies or IT departments, the remote monitoring function allows you to monitor the UPS status at any time without going to the site in person, especially when you need to manage multiple UPS. This function is particularly important.

Extended battery module: If you need a longer backup time, a UPS that supports external batteries allows you to adjust the battery life according to your needs, which is very flexible.

Summary

The choice of UPS should not blindly pursue high prices or rich functions. The most important thing is to find a device that suits your actual needs. Understand the use of your own equipment, clarify the priority of power guarantee, and then make a choice based on the budget and usage scenarios to make the UPS truly play its role.
