Choosing the Right Vertiv Liebert UPS: Key Considerations

In today's digitally-driven world, a reliable power supply is crucial for businesses of all sizes. Power outages and voltage fluctuations can wreak havoc on your critical IT equipment, resulting in costly downtime and potential data loss. That's where a Vertiv Liebert Uninterruptible Power Supply (UPS) comes into play. However, with a variety of UPS models available, selecting the right one for your specific needs can be a daunting task. In this article, we will explore the key considerations to help you make an informed decision when choosing a Vertiv Liebert UPS.

Understanding Your Power Needs

Before delving into the world of UPS options, it's essential to assess your power requirements thoroughly. Start by conducting a comprehensive audit of your IT infrastructure. Determine the wattage and voltage requirements of your critical equipment, including servers, switches, and storage devices. This will provide a clear picture of the power capacity you need from your UPS system.

Identifying Critical Loads

Not all devices are created equal when it comes to criticality. Identify the equipment that is mission-critical for your business operations. These are the devices that must remain operational even during power interruptions. Knowing your critical loads will help you determine the runtime and capacity needed from your UPS.


Consider your future growth when selecting a Vertiv Liebert UPS. Your power needs may evolve as your business expands. Opt for a UPS system that can be easily scaled to accommodate additional equipment without the need for a complete overhaul.

UPS Types

Vertiv Liebert offers various UPS types, each designed to address specific needs. Understanding these types will enable you to choose the one that best suits your requirements.


Line-Interactive UPS systems are ideal for small to medium-sized businesses. They provide basic protection against power surges and outages. If you have a limited budget and don't require extended runtime, this might be the right choice.

Online Double Conversion

For businesses with more critical power needs, an Online Double Conversion UPS is the go-to option. These systems provide continuous, clean power and are highly resilient against fluctuations. They are suitable for data centers and enterprises where downtime is not an option.


Choosing the right Vertiv Liebert UPS is a critical decision that directly impacts your business's continuity. By thoroughly assessing your power needs, understanding UPS types, and considering factors like runtime, redundancy, and support, you can make an informed choice that ensures your critical equipment remains protected.

Redundancy ensures uninterrupted power supply even if one component fails, preventing downtime and data loss.

4. What should I consider when evaluating the environmental suitability of a UPS system?

Take into account factors such as temperature, humidity, and physical conditions in your data center or equipment room.
