Functional Devices TR75VA007 Transformer

The Functional Devices TR75VA007 is a versatile, high-capacity 75VA step-down transformer engineered for reliable 24Vac power in demanding commercial hvac and building automation systems. Built with a split-bobbin construction, this unit offers multi-tap primary voltage flexibility, supporting 480/240/208/120Vac inputs. This makes it an ideal universal replacement for technicians managing diverse site voltages. To protect sensitive downstream controls, the TR75VA007 features an integrated manual reset circuit breaker, providing superior overcurrent protection compared to standard fused alternatives. The dual threaded hub mount and foot-mount design allow for secure attachment to electrical boxes or flat surfaces, ensuring a clean, NEC-compliant installation. With an 8-inch lead length and a wide operating temperature range of -30 to 140°F, this Class 2 transformer is a staple for professional contractors requiring a durable, high-performance power solution.

• Universal Voltage Compatibility: Multi-tap primary (120V to 480V) reduces the need to carry multiple transformer SKUs on the truck.
• Integrated Circuit Breaker: Simplifies troubleshooting and prevents permanent failure during short circuits or overloads.
• Flexible Mounting: Features both dual 0.5-inch NPT threaded hubs and a foot-mount base for versatile enclosure integration.
• Class 2 Rated: Meets UL5085-3 standards, ensuring safe operation for low-voltage control circuits.
• Compact Footprint: Efficient split-bobbin design fits easily into tight control panels without sacrificing 75VA power capacity.

• Can this transformer be used for 277Vac applications? No, the TR75VA007 is rated for 120, 208, 240, and 480Vac. Check the wiring diagram to ensure you are utilizing the correct color-coded lead for your primary supply.
• What do I do if the secondary side loses power? First, check the integrated circuit breaker. If it has tripped, identify and resolve the downstream fault before pushing the manual reset button.
• Is this unit suitable for outdoor use? While rated for a wide temperature range, this transformer should be installed within a NEMA-rated enclosure to protect against moisture and environmental contaminants.
