The Regulated Switching Power Adapter offers multiple voltage settings and multiple adapter tips to suit many product applications. All you need to do is select the correct voltage for your product, install the correct tip, connect to your product and plug it in. Unlike most adapters, the output voltage will be 12V when it is set on 12V, which is vital when powering LED lights. A non-regulated adapter will generally put out more voltage than it specifies causing irreparable damage.
