Resideo AT40A1121 Foot Mounted 120 VAC Transformer W/9" Lead Wires

The Resideo AT40A1121 is a small, efficient foot mounted transformer designed to power several HVAC components, such as Room Air valves. As a major component on many home and commercial HVAC systems, these valves need to operate correctly and safely. The transformer turns incoming electrical power of 120 VAC into a safe lower voltage of 26.5 volts, which is suitable for the fine circuitry used in RA valves. It protects the valves from any damage, and ensures peak performance. The transformer is built with a strong design and quality components, for long term endurance and reliability.
