The 120- to 12 volt transformer is an important electric device specially designed to change from a high voltage (120V) into much lower and safer (12V) voltage. Its primary function is to reduce the voltage from 120 to 12 volts, and so can provide stable and reliable power for many devices with low voltage requirements. Technological characteristics include a robust magnetic core for high efficiency and minimum losses in energy during transformations. Inconveniently, it is supplied with at least two multitude safety certifications that rule out happenings of electrical hazard. The transformer has found a wide range of application environments including occasions from residential to commercial settings and even to industrial installations. This is not to say that there's an area with only simple no-equipment requirements; very many sites use modern appliances such as security systems lighting for landscaping etc.
