Power Protection Devices
Certain devices protect your system from the effects of problems such as power surges and power failures.
l PDU — Uses circuit breakers to ensure that the AC current load does not exceed the PDU's rating.
l Surge protector — Prevents voltage spikes, such as those that may occur during an electrical storm, from entering the system through the electrical
outlet. They do not protect against brownouts, which occur when the voltage drops more than 20 percent below the normal AC line voltage level.
l Line conditioner — Maintains a system's AC power source voltage at a moderately constant level and provides protection from brownouts, but does not
protect against a complete power loss.
l UPS — Uses battery power to keep the system running when AC power is unavailable. The battery is charged by AC power while it is available so that
after AC power is lost, the battery can provide power to the system for a limited amount of time—from 5 minutes to approximately an hour. A UPS that
provides only 5 minutes of battery power allows you to save your files and to shut down the system. Use surge protectors and PDUs with all universal
power supplies, and ensure that the UPS is UL-safety approved.
