Popular Electronic Power Supply Terms
Whether running a computer, charging a phone, or feeding electricity to your favorite video game console, electric power supplies are a vital component in order for these pieces of equipment to run. To have a better, more comprehensive understanding of the terminology associated with electronic power supplies and sources, we must first understand the terms associated with them. Below are several popular terms used when describing electric power supplies.
AC - AC stands for Alternating Current. Broken down, it simply means the voltage or current which is periodically changing polarity. An AC supply is suitable for powering some devices such as lamps and heaters but almost all electronic circuits require a steady DC supply.
DC - DC stands for Direct Current or unidirectional voltage or current. A DC voltage is always positive or always negative, but it may increase and decrease. Cells, batteries and regulated power supplies provide steady DC which is ideal for electronic circuits.
Converter - A converter is a device that converts alternating current to direct current or vice versa.
Adapter - An adapter is a plug used to connect an electrical device to a main supply when they have different types of terminals. The term can also refer to a converter of electric current to a desired form.
Circuit - A circuit is a complete path through which an electric current can flow.
Amp or Ampere - An ampere is a unit of electric current. One ampere corresponds to a certain number of electrons passing a fixed point each second.
Volt - A volt is a unit of potential difference and electromotive force. It is formally defined to be the difference of electric potential between two points of a conductor carrying a constant current of one ampere, when the power dissipated between these points is equal to one watt.
Electronic power supplies help provide power to residential, commercial, and industrial units as an alternative to batteries or other power supplies. Electronic power supplies are essentially sources of electric power, including voltage and current, needed to operate circuits. Such supplies may include new and used parts, adapters, plug-ins, and AC/DC converters. Other supplies include generators, cords, high-voltage units, switches, and kits. Electronic power supply companies sell new and used parts, circuits, adapters, and more to companies in need of power supplies. Buying from a dealer can translate to significant savings, especially if you buy in bulk for your business. You can find electronic power supply dealers by looking in your local phone book or by searching online directory listings. Distributors and manufacturers of electronic power supplies sell bulk products to construction workers, contractors, retail home improvement stores, engineers, and other professionals. Consider whether you want a new or used part and target your search accordingly. Check out online auction sites to find a cheap deal on bulk items you need. You can save yourself a bit of money if you buy used parts and surplus items from private sellers and distributors. Take into account your budget and stick to it. Go online to research the latest in state-of-the-art power supply products for your particular industry and view catalog photos, product reviews, detailed product descriptions, and shipping and handling information. Look online for new and used supply products, accessory items, and electronic power supply dealers near you. Ask others in your business which manufacturers they use for their electronic power supply needs.
