The device I am going to talk about is used more in business offices and less for personal use. The Uninterruptible Power Supply (UPS) protects your computer/ server against power fluctuating levels. Moreover it can power up the PC during a blackout. Thus, you should realize the benefit of this device for the protection of your office PCs and valuable data. I hope you will find useful the next tips for buying a UPS.

1. Power specifications. Before buying a UPS you should check the power rating of the devices that need protection. For that, check the VA rating or amps multiplied by voltage (120V). The UPS must have a VA rating 20-25% higher than the necessary for your devices (PC, printer, scanner, router etc.) VA ratings range from 300VA (for personal use) to 3000VA for server farms.

2. Number of outlets. After deciding on the power specifications, a buyer should consider the number of outlets needed. For example, to connect two printers, a scanner, the PC, the monitor, speakers, a USB hub, and a phone you purchase a UPS with 8 outlets. Besides, it is recommended to know how many outlets provide both battery backup and surge protection.

3. Backup time. During a blackout an working office has a lot of valuable data in processing. Consequently, data losses must be prevented. It's obvious a UPS can't power the computer all day, but it gives the employees to save their work. Usually the UPS provides a backup time of around 10 to 20 minutes, which is more than sufficient to save the work and to shut down the system properly.

4. Software is another important variable for your acquisition. First ask about its features like battery-low alarms and overloading alerts. Also the software should give you adequate reports about the power management.

5. Warranty conditions. Choose the vendors that offer larger term warranties. Sign for on site warranty, to get the batteries replaced at your place. That way, you minimize the risks.

6. Battery replacement. The usual period of functioning is three years. But that could be reduced if your office encounters power outages frequently. The software reports could not be so accurate all the time, because producers often give wrong information to increase their battery sales. Specialists say it is advisable to buy replacement battery cartridges to refresh the UPSes with weak batteries.

7. Optimize its features. Use the UPS correctly. Don't plug in the printer or similar devices into the battery backup outlet. That one could be destined to PC, router or phone. Ground the UPS properly to avoid electrical hazards.

In conclusion, I would say a UPS is a good addition to any office. Perhaps some of you remember the 2003 US blackout that caused so many losses for those who didn't use a UPS.
