Resideo by Honeywell AT72D1006 40VA Transformer 120V to 24V Plate Mount

The Resideo by Honeywell AT72D1006 is a 40VA power transformer designed for HVAC control systems and other applications requiring reliable 24VAC power. This plate-mounted transformer steps down standard 120VAC line voltage to 24VAC, providing consistent power for thermostats, zone controls, and other low-voltage devices.

Key Features:

• 40VA power rating provides ample capacity for most residential HVAC control systems
• Primary voltage: 120VAC, 60Hz
• Secondary voltage: 24VAC
• Plate mount design for easy installation on junction boxes or control panels
• Class 2 rated for safe, code-compliant installations
• Screw terminal connections for secure wiring
• Thermal overload protection prevents damage from overcurrent conditions
• UL listed for safety and reliability

This transformer is commonly used as a replacement component in residential and light commercial HVAC systems when existing transformers fail or when additional 24VAC power capacity is needed. The compact plate mount configuration allows for flexible mounting options in tight spaces.
