Johnson Controls Y65F42-0 Class 2 Transformer 40VA 24VAC Multi-Mount

The Johnson Controls Y65F42-0 is a Class 2 rated transformer designed for HVAC control systems and building automation applications. This versatile transformer delivers 40VA power output at 24VAC secondary voltage, making it ideal for powering thermostats, zone controls, actuators, and other low-voltage control devices.

Key Features:

• Dual primary voltage options: 277VAC or 480VAC input for flexible installation
• 24VAC secondary output at 40VA capacity
• Class 2 rated for safe, compliant installations per NEC standards
• Multi-mount plate design allows versatile mounting options
• Thermal overload protection prevents damage from overcurrent conditions
• Compact footprint for space-constrained equipment installations
• UL listed for safety and reliability

This transformer is commonly used in commercial HVAC systems, rooftop units, air handlers, and building automation panels where higher primary voltages are standard. The plate-mount configuration provides secure installation directly to equipment panels or junction boxes. Class 2 rating ensures that secondary circuits are considered safe, low-energy circuits that require less stringent wiring methods.
