A battery backup, or uninterruptible power supply (UPS), is primarily used to provide a backup power source to servers and desktop computers.
In most cases, these include the server(s) and main computer housing business data,
In addition to acting as a power backup when the power goes out, most battery backup devices also act as power “conditioners” by ensuring that the electricity flowing to your computer and accessories is free from drops or surges.
If a computer is not receiving a consistent flow of electricity, damage can and often does occur.
A Smart-UPS has the ability to interact with Server and desktop operating system and allowing it to shut down the server or desktop gracefully, prevent hard shutdown (crash).
While a UPS system is not a required piece of a complete computer system, including one as part of yours is always recommended. The need for a reliable supply of electricity is often overlooked.
Uninterruptible power supply, uninterruptible power source, on-line UPS, standby UPS, and UPS are the different names for a battery backup.
What Size UPS do I Need?
Do it the old fashioned way! With a few simple questions and calculations, you can identify your power needs and find the right UPS. Follow these steps below. Our UPS Sizing Worksheet will help you get the job done right.
- List all equipment to be protected by the UPS.(Remember to include monitors, external hard drives, routers, etc.)
- List the amps and volts for each device. These ratings can typically be found on the label on the back of the equipment. Multiply amps by volts to determine VoltAmps (VA). Some devices may list their power requirements in watts. To convert watts to VA, divide the watts by power factor. For servers, the power factor is often 0.9.
- Multiply the VA by the number of pieces of equipment to get the VA subtotals.
- Add the VA subtotals together.
- Multiply the total by 1.2 to get the grand total. This step accounts for future expansion.
- Use the grand total to select a UPS. When choosing a UPS, be sure that the total VA requirement of supported equipment does not exceed the VA rating of the UPS.
