Its kinda in the name, it supplies power
Generally its used to refer to things that take power from the wall and convert it into a low DC voltage that most of your electronics use like USB power supplies or the power bricks that feed laptops.
A Class 2 power supply feeds low voltage DC to some device downstream. The Class 2 refers to a National Electric Code(NEC) rating which limits the max power, voltage, and current that can be provided by the supply so that its outputs are relatively safe to touch which is a good feature for things like Laptop chargers where an average untrained person is going to have access to the live DC connector.
