An appliance that steps down 110 or 220 volt AC home current and transforms it to DC in order to power an electronic device, appliance, or other piece of electrical equipment is known as a universal power supply.
It comprises of a transformer enclosed in a box with a cord and a wall plug on either end.
A switch on the box lets the user choose the output voltage, which is typically in the range between 1 and 20 volts.
A string of diodes is attached to the output to convert the AC current to DC.
Each output jack of a universal power supply is made to fit the input of a device that will operate at one of the chosen voltage values.
There isn’t a universal power supply that can power every piece of equipment, despite the fact that it can power many distinct types of equipment.
With their own transportable power supply, laptops, home appliances, audio, video, and other electronic devices can be powered from a standard household circuit.
These devices’ fragile electrical circuitry is protected by the transformer and diodes in the power supply, and losing the power supply—an all-too-common occurrence—makes them unusable.
Having a universal power source on hand is an easy method to resume using a device if its power supply has been lost because there is no universal input voltage that is suitable for all devices.
The ratio of the input voltage to the output voltage is determined by the relative number of turns made on the input and output coils that are both encircled by a central core in a transformer.
A universal power supply’s switch adjusts the output voltage by moving the point of connection to change the number of output coils from one to more than one.
By transferring current in one direction while cancelling it in the opposite, diodes convert AC current to DC.
There isn’t a universal power supply that can power every piece of equipment, despite the fact that it can power many distinct types of equipment.
Buyers should confirm that one will function before buying it to replace a laptop power supply or a supply for a delicate piece of electronic equipment by looking at the range of voltages it is rated for and the output connectors it comes with.
The output current rating of the power supply should match that of the device for which it will be utilized.
