Johnson Controls Y65T31-0 Penn Series Transformer to Transformers - Y65 40VA 120/208/240V 24V

The Johnson Controls Y65T31-0 is a versatile Penn Series Y65 transformer designed for HVAC control applications requiring reliable voltage conversion. This 40VA transformer accepts multiple primary voltage inputs of 120/208/240VAC and steps down to 24VAC secondary output, making it ideal for thermostats, zone controls, and other low-voltage control circuits.

Key Features:

• 40VA power capacity for robust control circuit operation
• Multi-tap primary voltage: 120/208/240VAC for flexible installation
• 24VAC secondary voltage output for standard HVAC controls
• External fitting design for easy panel or surface mounting
• 8-inch primary lead wires for convenient wiring connections
• Three screw terminals on secondary (one blind terminal for single-voltage applications)
• Penn Series quality construction for long-term reliability

This transformer is commonly used in residential and light commercial HVAC systems to power thermostats, relays, and control boards. The multi-voltage primary capability eliminates the need to stock multiple transformers, while the external mounting configuration provides flexible installation options in control panels, junction boxes, or directly to equipment.
