What to consider when buying a UPS?

Answered by Phillip Nicastro

When it comes to buying a UPS (Uninterruptible Power Supply), there are several key considerations that you should keep in mind. These considerations will help you determine the right UPS for your specific needs and ensure that you make an informed decision. Let’s take a closer look at each of these considerations:

1. Determine the size of the load that needs UPS protection: The first step in buying the right UPS is to assess the power requirements of the devices or equipment that you want to protect. This involves calculating the total power consumption of all the devices that will be connected to the UPS. Make sure to consider both the active power (Watts) and the apparent power (VA) as they may differ. This will help you determine the capacity or rating of the UPS that you need.

2. Assess the required UPS runtime: UPS runtime refers to the duration for which the UPS can provide backup power to your devices in the event of a power outage. It is important to assess the runtime requirements for your critical devices and applications. Consider how long you need to keep your devices powered during an outage and choose a UPS with an appropriate runtime. Keep in mind that the runtime is dependent on the load connected to the UPS, so make sure to consider this factor as well.

3. Determine the number of outlets required: Consider the number of devices that you need to connect to the UPS. This will help you determine the number of outlets you require. Ensure that the UPS you choose has enough outlets to accommodate all your devices. It’s also a good idea to consider future expansion and whether you may need additional outlets down the line.

4. Consider UPS installation requirements: UPS systems come in different form factors, such as tower or rack-mountable, so it’s important to consider your installation requirements. If you have limited space, a rack-mountable UPS might be more suitable. Additionally, consider the input and output voltage requirements of your devices and ensure that the UPS can meet these requirements.

5. Look for additional features and specifications: Depending on your specific needs, you may want to consider additional features and specifications of the UPS. For example, some UPS models offer surge protection, voltage regulation, or the ability to remotely monitor and manage the UPS. These features can provide added protection and convenience.

By considering these key factors, you can ensure that you choose the right UPS for your needs. It’s worth mentioning that personal experiences and situations can greatly influence the decision-making process. For example, if you have experienced frequent power outages in your area, you might prioritize a UPS with a longer runtime. Similarly, if you have limited space in your setup, you might opt for a rack-mountable UPS. It’s important to evaluate your specific requirements and choose a UPS that best meets your needs.
