Switched Mode Power Supply System is an electronic power supply unit that incorporates a switching regulator in order to be highly efficient in the conversion of electrical power. The System transfers power from a source like the electrical power grid to a load like a personal computer while converting voltage and current characteristics. The Switched Mode Power Supply System is usually employed to efficiently provide a regulated output voltage, typically at a level different from the input voltage. Switched Mode Power Supply System is suitable for indoor as well as outdoor applications.
