The phrase "mains voltage" is correct and commonly used in written English, particularly in technical or scientific contexts.
It refers to the standard level of electrical voltage provided by a power grid, typically around 120-240 volts in most countries. Example: "It is important to use the appropriate voltage converter when traveling to a country with a different mains voltage to avoid damaging your electronic devices."
According to [7, 16], the term "critical" load refers to an electric load that requires a well-regulated mains voltage.
If it has pegs, this is mains voltage (a GU10 fitting) and is no problem to change.
The magnetoresistance sensor technology provides direct isolation from the mains voltage and ferrite cores are not needed like Hall counterparts.
But instead I find myself making tea for the nice man who visits about once a month to help the printer work again because it is unbelievably sensitive to minor fluctuations in the mains voltage.
The zoo is also spending £5,000 installing a "voltage optimisation unit" to reduce the mains voltage of 240v down to 220v to help prevent any needless waste of electricity.
A power converter that steps-down the mains voltage of 220 V and 60 Hz to supply power to a micro-watt consuming wireless sensor node is presented.
If it is only wired for a different voltage than your mains voltage (mains voltage is usually 100 V to 240 V depending on your location) then you must have an electrician wire that outlet for you (unless you are an electrician yourself).
Power: With mains supplies ranging from 110 to 240 volts, a universal power supply is a must, most notebook power adaptors tend to be multi-voltage, but check before purchasing just in case.
It makes possible the use of actual mains voltages to compensate and mitigate the disturbances.
Now the first mains-voltage LEDs designed as direct replacements for incandescent bulbs are arriving on the market.
Therefore, it makes sense to first look at the effects of mains-like voltages, as these have been studied in great detail [10, 11].
