A North American power strip with two USB power ports that includes a built in surge protector. A power strip (also known as a multi-socket, power board and many other variations [a]) is a block of electrical sockets that attaches to the end of a flexible cable (typically with a mains plug on the other end), allowing multiple electrical devices to be powered from a single electrical socket.
Socket-outlet, auto switched by plug insertion. Automatically switched socket-outlets such as these may be used to supply power to refrigerators, some computers and other accessories that normally should not be switched off. The absence of a user operable switch prevents the accidental switching off of such devices Surface socket-outlet and plug.
A switchable power strip or power bar. Timers can be used to turn off standby power to devices that are unused on a regular schedule. Switches that turn the power off when the connected device goes into standby, [30] or that turn other outlets on or off when a device is turned on or off are also available. Switches can be activated by sensors.
3. Refrigerators and Freezers. The first thing they’ll tell you when you’re buying a new fridge is to plug it into a wall outlet. A power strip isn’t beefy enough for heavy-duty appliances ...
Internationally, the NEMA 5-15P plug and NEMA 5-15R receptacle are the basis for the International Electrotechnical Commission's IEC 60906-2 standard IEC system of plugs and sockets-outlets for household and similar purposes – Part 2: Plugs and socket-outlets 15 A 125 V a.c. and 20 A 125 V a.c. [24]
In contrast, a linear power supply regulates the output voltage by continually dissipating power in the pass transistor. The switched-mode power supply's higher electrical efficiency is an important advantage. Switched-mode power supplies can also be substantially smaller and lighter than a linear supply because the transformer can be much smaller.
Moving heads connected to a plug-in box (center). In stage lighting, a plug-in box, plug box [1] or drop box [2] is a device, similar to a power strip, to distribute power to multiple lighting instruments, consisting of an inlet (either detachable or hard-wired), and multiple female outlet connectors or pigtails.
BS 546, Two-pole and earthing-pin plugs, socket-outlets and socket-outlet adaptors for AC (50–60 Hz) circuits up to 250 V is an older British Standard for three-pin AC power plugs and sockets. Originally published in April 1934, it was updated by a 1950 edition which is still current, [ 1 ] with eight amendments up to 1999.
