Class 2 Transformers with Secondary Circuit Protection

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.

Class 2 Transformers

Class 2 transformers deliver power of 100 VA or less with a maximum output voltage of 30 VAC or less. Raptor Supplies offers a huge range of transformers from brands like Altronix, Dayton, Edwards Signaling, Functional Devices / RIB, Johnson Controls, Robertshaw, Square D and White-Rodgers. Dayton Class 2 transformers are designed for gas valves, thermostats & relays.They feature a fixed apparent power rating of 40 VA and are UL & cULus listed for use in electrical components. These transformers can be used to replace any other transformer of the same primary & secondary voltages and of equal or smaller power ratings. Single phase Class 2 transformers from Functional Devices / RIB are available with single / dual threaded hubs and pigtail wires. These transformers utilise split-bobbin construction for superior isolation and low capacitive coupling. These transformers are available in enclosed, indoor and open enclosures.
