  2. Power conditioner - Wikipedia

    en.wikipedia.org/wiki/Power_conditioner

    A power conditioner (also known as a line conditioner or power line conditioner) is a device intended to improve the quality of the power that is delivered to electrical load equipment. The term most often refers to a device that acts in one or more ways to deliver a voltage of the proper level and characteristics to enable load equipment to ...

  3. Mains electricity by country - Wikipedia

    en.wikipedia.org/wiki/Mains_electricity_by_country

    (For industrial machinery, see industrial and multiphase power plugs and sockets.) Some countries have more than one voltage available. For example, in North America, a unique split-phase system is used to supply to most premises that works by center tapping a 240 volt transformer. This system is able to concurrently provide 240 volts and 120 ...

  4. Power supply - Wikipedia

    en.wikipedia.org/wiki/Power_supply

    A power supply is an electrical device that supplies electric power to an electrical load. The main purpose of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load. As a result, power supplies are sometimes referred to as electric power converters. Some power supplies are ...

  5. Voltage converter - Wikipedia

    en.wikipedia.org/wiki/Voltage_converter

    A simple voltage dropper can be used to reduce the voltage for low-power devices; if more than 12V is required, or for high-powered devices, a switched-mode power supply is used. The output will usually be DC in the range 1.5–24 V. Power supplies that output either 100–120 V AC or 210–240 V AC are available; they are called inverters ...

  6. Split-phase electric power - Wikipedia

    en.wikipedia.org/wiki/Split-phase_electric_power

    Higher-power appliances, such as cooking equipment, space heating, water heaters, clothes dryers, air conditioners and electric vehicle charging equipment, are connected to the two line conductors. This means that, for the supply of the same amount of power, the current is halved.

  7. Voltage optimisation - Wikipedia

    en.wikipedia.org/wiki/Voltage_optimisation

    Voltage optimisation is an electrical energy saving technique which is mainly installed in series with the mains electricity supply to provide a reduced supply voltage for the site's equipment. Typically, voltage optimisation can improve power quality by balancing phase voltages and filtering harmonics and transients from the supply, although ...
