Functional Devices TR50VA006 Transformer

The Functional Devices TR50VA006 Transformer is a heavy-duty 50VA control transformer optimized for 277Vac to 24Vac power conversion in commercial HVAC and building automation systems. Built with a reliable split-bobbin design, this Class 2 rated transformer is ideal for driving relays, powering sensors, and supporting digital I/O circuits in high-voltage environments. It features integrated 3amp fuse over current protection to safeguard downstream components from electrical faults. The versatile foot and single threaded hub mount configuration allows for secure installation directly onto electrical boxes or within control panels. With an ambient operating range of -30°F to 140°F and color-coded wire leads, the TR50VA006 provides a robust 24V power supply solution for contractors managing voltage reduction in 277V lighting or mechanical circuits.

• High-Efficiency Power Conversion: Converts a 277Vac primary input to a stable 24Vac secondary output with a 50VA capacity.
• Integrated Circuit Protection: Includes a factory-installed 3-amp fuse to prevent equipment damage during over-current events.
• Flexible Mounting Options: Supports both surface foot mounting and single threaded hub installation for standard knockouts.
• Industrial Durability: UL Listed and Class 2 rated, ensuring compliance for building automation and temperature control applications.
• Professional-Grade Wiring: Pre-stripped 8-inch color-coded leads simplify field connections for faster installs.

Is the TR50VA006 compatible with 120V circuits?
No, this specific model requires a 277Vac primary voltage. For 120V applications, we recommend checking the TR series for the appropriate primary voltage rating.

Can I use this transformer to power a 24V HVAC thermostat?
Yes, provided the total load does not exceed 50VA. This unit is frequently used to provide control power for thermostats, dampers, and controllers.

What happens if the fuse blows?
The integrated 3-amp fuse is designed to protect the secondary circuit. If the fuse opens, it indicates a downstream overload or short that must be addressed before replacing the fuse.
