power line conditioners

A power strip (also known as a plug board, power board, power bar, distribution board, gangplug or multibox) is a strip of sockets that attaches to the end of a flexible cable and allows multiple devices to be plugged in. As such it can be considered a type of trailing socket though that term is more often used for single and double cable mounted sockets. The term is also used to refer to the complete assembly with the power strip on one end and a plug on the other. Power strips are often used when many electrical devices are in proximity, especially with audio/video and computer systems.

Control

Power strips can include a switch to turn all devices on and off. Powervar Power Line Conditioners and UPS Systems. In a few cases they may even have all outlets individually switched. Some very expensive strips exist that can detect one device being turned on (say the PC itself in a computer setup) and turn everything else on. Remote control strips also exist to allow a group of devices to be switched remotely.

Surge Protection and Filtering

Many power strips have built in surge protectors and/or EMI/RFI filters: these are sometimes described as electrical line conditioners. Some also provide surge suppression for phone lines, TV cable coax, or network cable. Power Conditioners.
