What to look for
Power Capacity
When choosing a UPS for servers, consider its power capacity, measured in VA (volt-amperes). A higher VA rating means that it can support more devices or handle higher loads. For servers, aim for at least 1000VA to ensure all your critical equipment stays online during outages.
Number of Outlets
Look for a UPS with enough outlets to connect all your devices. Consider the split between battery backup and surge-only outlets. For server setups, at least 6-8 battery backup outlets are recommended to protect essential equipment without overloading.
Runtime
Runtime is how long a UPS can provide power during an outage. Choose a model that offers at least 15-20 minutes of runtime at full load. This allows you enough time to save work and shut down safely.
Type of Output
Different UPS models provide different types of output. Sine wave output is best for sensitive electronic equipment. If you have a server with active PFC power supplies, ensure your UPS provides pure sine wave output for optimal performance.
Features and Indicators
Many UPS models offer additional features like LCD displays for monitoring battery status and runtime. Look for models with easy-to-read indicators. Helpful features can include ECO mode for energy savings and USB ports for connecting to a computer.
How to Choose Ups
Understanding VA Ratings
VA ratings tell you how much power a UPS can handle. For servers, look for a UPS with at least 1000VA. This ensures it can support your equipment during a power outage, providing enough backup time.
Choosing the Right Output Type
The output type matters greatly. Sine wave output is ideal for servers, especially those with active PFC power supplies. Make sure the UPS you choose has this feature to protect sensitive electronics.
Assessing Runtime Needs
Consider how long you need the UPS to work during an outage. Aim for at least 15 minutes of runtime at full load to give you time to save all work. This way, you can safely shut down your devices.
Outlet Configuration
Look for a UPS with a good mix of battery backup and surge-only outlets. For server use, a minimum of 6-8 battery backup outlets is recommended. Ensure it can accommodate all your essential devices.
Additional Features
Check for useful features like LCD displays and USB ports. An LCD panel can provide real-time info on battery and power status. USB ports allow for easy connections to computers for monitoring.
