Dayton Class 2 transformers are suitable for low-voltage devices (up to 480VAC), such as thermostats, gas valves, relays and others. These units are used in conjunction with secondary circuits that are considered safe from a fire initiation standpoint and prevent chances of a shock due to the power limitations of the class 2 transformers. They are available in open and enclosed type enclosures and are compliant with UL and cURus standards.
