A power supply is a device that supplies electric power to an electrical load. The term is most commonly applied to electric power converters that convert one form of electrical energy to another. A regulated power supply is one that controls the output voltage or current to a specific value; the controlled value is held nearly constant despite variations in either load current or the voltage supplied by the power supply's energy source.

NF Corporation
In 1959, NF Corporation was founded with the noble mission of providing the world with unique products using its high-precision negative feedback control technology, a technique not quite widespread in Japan at that time. This pioneering spirit is still alive today at NF, which has been proactively pursuing new fields and developing new products with the aim of contributing to the next-generation R&D and, through that, to advancing society. The proprietary technology of NF is used in a wide array of applications––from automobiles, digital appliances, and other high-tech electronic devices to fuel cells, solar power, and other clean energy technologies, as well as nanotechnology and even satellite, rocket, and other aerospace technologies.
