Resideo AT87A1155 Transformer
Upgrade your industrial or commercial HVAC control systems with the Resideo AT87A1155 Transformer. Designed for high-voltage environments, this 480V to 24V step-down transformer provides a reliable 48VA power supply to run air conditioning circuits, 24V thermostats, and building automation controllers. As a NEMA Type E transformer, it features built-in energy limiting overload protection per NEC Class 2 standards, ensuring your low-voltage components are shielded from electrical faults during operation. The foot-mount design and 12-inch color-coded leadwires facilitate a fast, standard installation for field technicians managing multi-tap primary configurations.
Key Benefits- Precise Voltage Conversion: Efficiently steps down 480V primary power to a stable 26.5V VOC secondary output for sensitive 24VAC control modules.
- Integrated Safety: Features energy limiting protection and meets UL 1585 requirements, eliminating the need for external fusing in many Class 2 applications.
- Industrial Durability: Robust foot-mounted construction engineered for longevity in demanding boiler rooms and mechanical spaces.
- Contractor-Friendly Install: Pre-stripped 12-inch wire lead connections allow for simplified integration into existing control panels.
- Is the AT87A1155 compatible with older 480V HVAC units? Yes, this unit is a standard replacement for 480V primary systems requiring a 24V-27V secondary output, provided the load does not exceed 48VA.
- Can this transformer be used in damp locations? This model meets NEC Class 2 "not wet" and Class 3 "wet" requirements, making it suitable for a wide range of mechanical environments.
- How do I identify the primary and secondary wires? The Resideo AT87A1155 utilize standard color-coded leadwires; always refer to the specific wiring diagram on the housing to confirm 480V input terminals.
