- 1). On the web, you can visit one of the UPS vendor sites. They have information on all of the products they market and also have a selector application that will guide you to selecting the correct UPS. One of the most important selection factors is how important battery backup will be to your business. For example, in an aircraft, the battery would keep the radio and oxygen systems running due to engine failure until the plane could land safely. A hospital must have power to keep patients on life support and to keep other equipment running.
- 2). You can contact a local electrical supply company. If your UPS is for a commercial application, such as a business, they can advise you on what to select. Battery backups are used for burglar alarms, since they prevent the alarm from being disabled when the thief turns off the building power. They can also power the phone system so that cutting the phone line will not disable cellular telephone service. They are most often used to provide power for computers, servers, printers, and networking equipment. A UPS also provides surge and static electricity protection. The company may also carry much larger systems for a data center or networking facility backup. NASCAR cars always carry a lightweight spare so that, in the event of a collision, the driver can finish the race.
- 3). You can visit one of several electronic retail stores if your needs are only for a home use computer and printer.
