Determining your backup power supply needs is a tricky and complex procedure. There are many types of backup power supply hardware. Uninterruptible power supply is one of the most common types of backup power supply hardware. The type of UPS you choose is largely determined by your facility’s electricity consumption.

Determining Power Needs

The first step to take when determining your backup power needs is to decide which devices need backup power supply. Generally, computers and monitors are some of the devices you will need to power in the event of a power interruption. The maximum power usage of your monitor and computer is usually indicated on the user manuals of each device. Adding the maximum power wattage of your computer and monitor will help you determine the power usage of the two devices. Uninterruptible power supply units help to prevent data loss by allowing you time to save your work and shut down the system in the event of an interruption in power supply.

Determining Unit Requirements

Research UPS prices and determine your price limit. UPS manufacturers usually indicate volt-amps and wattage of their uninterruptible power supply units in their products’ packaging. The most important information to consider in determining unit requirements is the wattage of your intended UPS hardware. Choose a UPS device that meets and exceeds the power demands that you had previously determined. The next factor to consider is how long the UPS will run under full load. This may not be clearly indicated on the device package and you may have to go through the device manual for this information.

Rules of Thumb for When Specifications are Unavailable

The number of batteries in a UPS device determines how long the unit will run at full load. Generally, the more the batteries, the longer the run-time at full load. If you cannot find the information on run time at full load, choose the largest power supply that meets your wattage needs and budget.

Testing the Unit, or Confirming Your Choice

Unless you test the UPS device, all the research and shopping in the world will not help you determine if your UPS device is working or not. Check the manual of the UPS device and make sure the device specifications meet your needs. Plug your computer and monitor into your UPS and plug in the UPS to let it charge. Once the UPS is fully charged, unplug it and see for how long it will power your devices before it runs out. This will help you determine if you need to replace the UPS with a larger one or if it will suffice.

An uninterruptible power supply provides backup power supply to electrical devices in the event of a power outage. This device converts direct current electrical energy into alternating current electrical energy, which is supplied to plugged-in electrical devices. There are many factors to consider when purchasing or leasing UPS hardware including full-load wattage, usability features, volt-amp rating and run-time at full power. You can purchase a UPS device from a computer hardware store or lease one from a UPS rental.
