Servers, network equipment, communications equipment, security systems, and other devices are typically equipped with uninterruptible power supplies (UPS) to ensure that these critical systems can continue to operate normally in the event of a power outage. However, the available installation space for the UPS is generally limited. And 1RU UPS can be deployed within a confined space, minimizing the amount of valuable space occupied by critical equipment.
What is 1RU UPS mean?
1RU UPS refers to a rack mounted UPS with a height of 1U. The “R” here stands for rack mounted uninterruptible power supply. And “U” represents the unit of height for rack mounted equipment. One U equals 1.75 inches (approximately 44.45 millimeters). In applications such as data centers and network equipment, devices and lithium UPS are often installed in standard 19-inch racks. The height of 1RU UPS is specifically designed to provide power protection for equipment within the limited space of a standard rack. Although 1RU UPS is relatively slim, it retains all the functions of a conventional UPS.

What is the difference between UPS 1U and 2U?
The most basic difference between 1RU UPS and 2U UPS is their height. Our 1kVA 2kVA 3kVA rack mount UPS is standard 2U lithium UPS systems. 1RU UPS can be deployed in very limited space but offers relatively low power output. In contrast, 2U lithium UPS can provide higher capacity and better heat dissipation. When rack space is critical and available space is very limited, 1RU UPS is an excellent choice. If your equipment requires higher power, 2U UPS is better suited for your needs.
What are the key features of 1RU UPS?
- Extremely compact: In a standard rack, 1RU UPS can be deployed in server rooms, communication centers, and other spaces where space is limited, providing reliable power protection for your business operations. Additionally, although the 1RU UPS is a rack mounted unit, you can choose between rack-mounted or tower-style installation depending on your application needs or preferences.
- Provides reliable power support: Compared to conventional lithium UPS systems, the 1RU UPS is relatively compact. But it can still offers comprehensive power protection features. Furthermore, when mains power is interrupted, it can immediately switch to battery power to ensure your equipment keeps running. During this time, you’ll have ample time to save data, shut down the equipment properly, or wait for a generator to restore power.
- Quick and easy deployment: With the compact size and weight of 1RU UPS, a single person can handle both transportation and installation without the need for multiple people or mechanical equipment. Moreover, most 1RU UPS units today are plug-and-play. In future use, if you need to replace the battery, it can be done online without interrupting business operations.
Is it worth buying 1RU UPS for my project?
If the power consumption of your equipment is low and rack space is limited, it is worth purchasing 1RU UPS to ensure business continuity. The 1RU UPS design is compact and can be installed in a standard 19-inch rack. It not only saves floor space but also does not occupy U-space intended for servers, network storage, and other equipment. Furthermore, it can be installed quickly and supports plug-and-play functionality. And battery maintenance and replacement can all be performed online. More importantly, in the event of a power outage, it can provide a period of backup power to ensure equipment can shut down properly, safeguarding data integrity. On the other hand, if your equipment has a high total power consumption, operates in an environment where power outages last a long time, and requires extended runtime, we recommend choosing 2RU UPS or a larger-capacity lithium UPS.
What are the key factors need to be considered when selecting 1RU UPS?
- Power rating of 1RU UPS: When selecting a 1RU lithium UPS, you should confirm the total power consumption of your equipment. Meanwhile, you should also consider the equipment’s inrush current and add a certain amount of power to ensure the UPS does not shut down due to excessive inrush current during startup. If you have plans for future business expansion, you may also consider choosing a 1RU UPS with a higher power rating.
- Battery backup time: Typically, a 1RU UPS with built-in batteries. So it can provide approximately 15 minutes to half an hour of backup power in the event of a mains power failure. If you require a longer backup time, please consult your supplier for a customized solution.
- Rack space: When purchasing a 1RU UPS, be sure to verify the depth of both the rack and the UPS to ensure that the cabinet door can close properly after the UPS is installed.
- Other features: You can choose the interfaces for the 1RU UPS and decide whether you need an SNMP card or other features based on your actual usage.
Conclusion
The 1RU UPS can provide reliable and stable power support for critical equipment in limited rack space. Its compact design enables deployment in confined spaces. However, it also means that its power capacity and runtime are limited. If your application requires higher power, please contact us for a better lithium UPS solution.
