Resideo AT150F1022 Transformer
The Resideo AT150F1022 is a heavy-duty 50VA control transformer engineered for reliable power distribution in commercial and residential HVACR systems. Built for professional-grade duty cycles, this multi-tap transformer features primary voltage inputs of 120V / 208V / 240V and steps down to a stable 24V secondary output. Designed with NEC Class 2 compliance, it is ideal for powering zone controllers, relays, and digital thermostats where predictable, uniform loads are required. The AT150F1022 is distinguished by an integrated manually resettable circuit breaker, providing critical overcurrent protection without the need for periodic fuse replacements. Its versatile multi-mount configuration supports foot, plate, or panel mounting, utilizing a 1/2-14 NPSM conduit connector and locknut for high-integrity installations in 7/8-inch knockouts. The unit includes 9-inch color-coded lead wires for the primary and screw terminals for secondary connections, housed within a rugged metal end-bell enclosure for terminal protection.
Key Benefits for Contractors- Universal Voltage Compatibility: Multi-tap primary supports 120, 208, and 240 VAC, reducing the need to carry multiple SKUs on the service truck.
- Integrated Circuit Breaker: Features a manual reset button to protect against secondary shorts and overloads, simplifying troubleshooting and increasing system resilience.
- Advanced Mounting Options: Flexible hardware base allows for foot mounting on flat surfaces or hub/plate mounting directly to electrical boxes.
- Industrial Build Quality: Constructed with metal end bells and UL 1585 certification, ensuring performance in environments ranging from -20°F to 105°F.
- Clean Installation: Color-coded 9-inch leads and clear terminal markings streamline wiring for control panels and air handlers.
What is the difference between the AT150F and standard 40VA transformers?
The AT150F provides a 50VA rating, offering higher current capacity for systems with multiple relays or complex zone dampening. It also includes an integrated manual reset breaker, which is not standard on basic 40VA models.
Can this be mounted inside a NEMA enclosure?
Yes, it is designed for panel and plate mounting. The included 1/2" conduit connector and locknut allow it to secure directly to an enclosure knockout for a code-compliant, professional finish.
How do I handle the secondary voltage for sensitive electronics?
The secondary is rated at 24 VAC under load, though it may read as 27.5 V.O.C. (volts open circuit). This is standard for Class 2 transformers and is compatible with all 24V HVACR control systems.
