Functional Devices TR50VA027 Transformer
The Functional Devices TR50VA027 is a heavy-duty 50VA class 2 transformer engineered for reliable step-down power conversion in commercial HVACR and building automation systems. Built for 240Vac primary input, this unit provides a stable 24Vac secondary output, making it an essential component for powering low voltage control circuits, actuators, and digital controllers. This model features a versatile dual mounting configuration, utilizing both a foot mount and a single 1/2-inch threaded hub, which allows for secure installation on standard electrical junction boxes or inside air handler cabinets.
For enhanced circuit protection, the TR50VA027 includes an integrated manual reset circuit breaker. This critical safety feature prevents winding failure and protects downstream 24V HVAC controls from over-current conditions and short circuits without requiring fuse replacements. When spec'ing a commercial step-down transformer, the high-quality copper windings and pre-stripped lead wires on this unit ensure minimal voltage drop and rapid field integration for service technicians and controls contractors.
Key Benefits for Technicians:- Integrated Over-Current Protection: Built-in manual reset breaker eliminates the need for external fusing and protects the secondary circuit.
- Rugged Mounting Options: Foot mount and threaded hub design provide flexibility for internal panel mounting or external box attachment.
- High 50VA Capacity: Provides ample VA rating for HVAC transformers to handle multiple solenoids, relays, and smart thermostats simultaneously.
- UL Class 2 Rated: Meets rigorous safety standards for use in energy-limited power circuits.
Can this transformer be used with 208V primary power?
No, the TR50VA027 is specifically wound for a 240Vac primary voltage. Utilizing it with 208V will result in a proportional drop in secondary voltage, which can cause erratic behavior in control systems.
What is the purpose of the manual reset breaker on this model?
The breaker acts as an auto-reset thermal protection alternative, allowing you to quickly restore power after a fault is cleared rather than replacing a blown fuse or the entire transformer body.
Is this unit suitable for outdoor rooftop units?
While the transformer is robustly built, it should be installed within a NEMA-rated enclosure or the equipment cabinet to protect the 18AWG lead wires from environmental degradation.
