Power low-voltage HVAC control systems with the Packard PF12440 40VA Class II Foot Mount Transformer. It's designed to provide reliable 24V output from a 120V line voltage source. Ideal for use in thermostats, relays, and furnace control circuits, this compact transformer supports a wide range of residential and light commercial heating and cooling applications. The Class II design limits output current to meet NEC safety requirements and helps prevent system damage in the event of overload. Featuring a standard foot-mount base and wire lead connections, this class 2 transformer installs easily in control panels, air handlers, and furnace cabinets. Mounting holes are spaced 2.756-in. (70 mm.) apart for compatibility with most HVAC equipment. Built to replace transformers with equal or lower VA ratings, this 40VA foot mount transformer is trusted by technicians for both field repairs and new installations in air conditioning, heat pump, and furnace systems.
