On the other hand, if the power supply has a voltage selector switch, based on the Delon circuit, for 115/230 V (computer ATX power supplies typically are in this category), the selector switch would have to be put in the 230 V position, and the required voltage would be 325 VDC (230 × √2).
Queensland began the transition to 230 V in 2017. [28] The reason given for Queensland's decision to move was the increased use of grid-tied rooftop solar installations raising the grid voltage. By lowering the voltage to 230 V, additional headroom of 960 megawatts was created to accommodate future residential power generation from rooftop solar.
A typical flyswatter. A flyswatter (or fly-swat, fly swatter [1]) usually consists of a small rectangular or round sheet of a lightweight, flexible, vented material (usually thin metallic, rubber, or plastic mesh) around 10 cm (4 in) across, attached to a handle about 30 to 60 cm (1 to 2 ft) long made of a lightweight material such as wire, wood, plastic, or metal.

The original Mosquito design was updated in 2001 as the Mosquito NRG, which remained in production until 2022. The NRG incorporates a flat back plate, front opening, propeller brake, integrated controls and electric starting. [2] Wings that are approved for the Mosquito include the A-I-R Atos rigid wing the Icaro Piuma and the Aeros Discus M ...
An electropermanent magnet or EPM is a type of permanent magnet in which the external magnetic field can be switched on or off by a pulse of electric current in a wire winding around part of the magnet. The magnet consists of two sections, one of "hard" (high coercivity) magnetic material and one of "soft" (low coercivity) material. The ...
A power supply unit (PSU) converts mains AC to low-voltage regulated DC power for the internal components of a desktop computer. Modern personal computers universally use switched-mode power supplies. Some power supplies have a manual switch for selecting input voltage, while others automatically adapt to the main voltage.
An external power supply, AC adapter or power brick, is a power supply located in the load's AC power cord that plugs into a wall outlet; a wall wart is an external supply integrated with the outlet plug itself. These are popular in consumer electronics because of their safety; the hazardous 120 or 240 volt main current is transformed down to a ...
