The 3 Types of UPS and Which is Best for You

In previous blogs, we have discussed the importance of having an Uninterruptible Power Supply (UPS) system safely installed for important devices in the occurrence of sudden power loss, failure, or surges. Not only does a UPS safeguard your data, but it also ensures key activities of a device run smoothly and unaffected by sudden power changes. If you have decided that a UPS is a suitable power protection solution for you, you may still feel overwhelmed and unsure of the different types of UPS and which one to choose, especially with dozens of options available on the market. 

If that’s you, read on and learn more about the 3 types of UPS and their key features, mechanisms, and unique advantages. 

Standby (Offline) UPS 

Standby UPS delivers short-term, battery-sourced power during power outages. It protects against most spikes but doesn’t maintain perfect power during minor sags and surges. The switchover time to battery power takes up to 25 milliseconds, which is well within the tolerance threshold of most electronics. Commonly used to protect computers, modems, VoIP equipment, and other less critical hardware, Standby UPS is perfect for home and professional environments with less than 1500VA capacity. When compared with other types of UPS, Standby UPS is the most cost-effective choice. 

Some of Northern Lights Data Standby UPS products are APC Back-Ups CS500 USB/Serial, APC Back-ups CS650VA 230V, and others. 

Line-Interactive UPS 

Line-Interactive UPS provides both power conditioning and battery back up, regulating voltage automatically. It will maintain performance during low voltage situations and short-term power failures, however, when capacity has been exceeded, its battery power allows devices to be shut down safely. The switchover time to battery power takes up to 6 milliseconds, which is slightly faster than Standby UPS. Home and professional environments with more than 1500VA, but less than 5000VA capacity should go for the Line-Interactive UPS. When compared to the Standby UPS, Line-Interactive UPS provides better control over power fluctuations. However, it is also more costly than Standby UPS, but more affordable than Online Double Conversion UPS. 

Some of Northern Lights Data Line-Interactive UPS products are Eaton 1200VA/720W Line Interactive UPS LCD (MOQ14), Eaton 850VA /510W Line Interactive UPS LCD (MOQ21), Vertiv PSA – 1000VA Mini Tower UPS, and many more. 

Online Double Conversion UPS

Online Double Conversion protects fully against all power disturbances due to its sine wave output. Its double conversion mechanism, converting AC to DC and vice versa, allows the power load to be isolated from irregularities of the main supply. Not just that, there is no switchover time when transferring to the battery, protecting equipment from all forms of power disturbances and changes. Online Double Conversion UPS is used mostly to protect large data centres and highly critical equipment. When compared to Standby UPS and Line-Interactive UPS, Online Double Conversion UPS costs the most, as it offers a premium, top-of-the-line power protection solution. 

Some of Northern Lights Data Online Double Conversion UPS products are Eaton 9130 3000VA/2700W Online Tower UPS, Liebert GXT4 On-Line 3000VA, and many more. 

Final Words 

When looking for an Uninterruptible Power Supply (UPS) system, make sure to understand the three different types and what they mean for you. If affordable cost is a priority, the Standby UPS could be just right for you, given that you do not require automatic battery switch over and your equipment is not highly critical.

However, if you are looking for a UPS for data centres and critical equipment, Online Double Conversion UPS is most suitable for your needs. This is because there is no battery switch over time and it can protect your equipment against all forms of power disturbances. In the world of UPS, Line-Interactive UPS is a mid-range product. Catering to home or work environments of middle scale, it costs more than Standby UPS, but less than Online Double Conversion UPS. Visit our website for more power protection solutions.
