Every lab needs to have a neat and constant current or voltage source known as Power Supply. Power supplies are the most common equipment found in any electrical & electronics lab. In the lab, power supplies are used for various forms of inputs. But these power supplies are directly linked to the efficient working of the equipment being tested. If there are any forms of abnormality in the supply, then there will be variation in the output resulting in wrong diagnostics. Thus, the power supply in the labs plays a vital role in the testing conducted in these labs. Power supplies are equipments in the lab that are used to give current or voltage outputs for use in various other appliances. Power supply is a reference to a source of electrical power. A device or system that supplies electrical or other types of energy to an output load or group of loads is called a power supply unit or PSU . These PSUs have their own properties and inputs from a common source like an
