Daikin-McQuay 062986902 Transformer

The Daikin-McQuay 062986902 Transformer is a heavy-duty 75VA control power transformer engineered for high-demand HVACR applications. This OEM Daikin replacement part features a 120V primary voltage and a 24V secondary output, making it the standard step-down solution for powering thermostats, contactors, and integrated circuit boards. Designed to handle the inductive inrush loads common in commercial air handlers and rooftop units, this transformer ensures stable voltage regulation across the control circuit. Its robust construction minimizes core saturation and heat dissipation issues, providing reliable signal integrity even in high-ambient environments. For technicians performing HVAC 24V transformer troubleshooting, this 75VA rated unit offers the necessary overhead to prevent nuisance tripping of 3-amp or 5-amp fuses. Precise terminal spacing and a standard footprint allow for efficient mounting within existing control cabinets, ensuring full compatibility with McQuay legacy systems and modern Daikin equipment.

• High 75VA Capacity: Provides ample power for complex multi-stage control circuits without voltage drop.
• OEM Compatibility: Direct drop-in replacement for Daikin-McQuay 062986902, eliminating the need for field modifications.
• Industrial Grade Insulation: Designed to withstand the thermal cycles of continuous commercial operation.
• Standardized Voltage: Accurate 120V to 24V conversion for precise component activation.

Is the 062986902 compatible with legacy McQuay air handlers?
Yes, this unit is a direct OEM replacement for the specific part numbers used in McQuay Agility and Maverick series units requiring 75VA of control power.

Can I use this to replace a 40VA or 50VA transformer?
Technically, yes. Increasing the VA rating provides more "headroom" for the control circuit, provided the primary and secondary voltages match your system’s requirements.

Does this transformer include an internal circuit breaker?
This specific model relies on external fusing or integrated board protection. Always verify the amperage rating of your secondary fuse when installing 24V control components.
