Power button marked with Standby symbol (IEC 60417-5009) turns the device on or off without fully disconnecting power supply. A power symbol is a symbol indicating that a control activates or deactivates a particular device. Such a control may be a rocker switch, a toggle switch, a push-button, a virtual switch on a display screen, or some ...
Standby power. Standby power, also called vampire power[1], vampire draw, phantom load, ghost load, or leaking electricity, refers to how electronic and electrical appliances consume electric power. At the same time, they are switched off (but are designed to draw some power) or in standby mode. It only occurs because some devices claim to be ...
An uninterruptible power supply (UPS) or uninterruptible power source is a type of continual power system that provides automated backup electric power to a load when the input power source or mains power fails. A UPS differs from a traditional auxiliary / emergency power system or standby generator in that it will provide near-instantaneous ...
Auxiliary power. Auxiliary power is electric power that is provided by an alternate source and that serves as backup for the primary power source at the station main bus or prescribed sub-bus. An offline unit provides electrical isolation between the primary power source and the critical technical load whereas an online unit does not. A Class A ...
Leakage current is also any current that flows when the ideal current is zero. Such is the case in electronic assemblies when they are in standby, disabled, or "sleep" mode (standby power). These devices can draw one or two microamperes while in their quiescent state compared to hundreds or thousands of milliamperes while in full operation.
Standby generator. A standby generator is a back-up electrical system that operates automatically. [1] Within seconds of a utility outage an automatic transfer switch senses the power loss, commands the generator to start and then transfers the electrical load to the generator. The standby generator begins supplying power to the circuits. [2]

Energy Star (trademarked ENERGY STAR) is a program run by the U.S. Environmental Protection Agency (EPA) and U.S. Department of Energy (DOE) that promotes energy efficiency. [4] The program provides information on the energy consumption of products and devices using different standardized methods. The Energy Star label [5] is found on more than ...
