Every mains-powered electronic device requires a power supply with specific characteristics. As a starting point, designers must consider the components of the power supply (size, shape, weight, and other physical characteristics), as well as the input and output voltages it supports, power capacity, efficiency, reliability, and so on. The final environment where it will be used is also important.
