Resideo AT150B1260/B Transformer
The Resideo AT150B1260/B Transformer is a heavy-duty 50VA HVAC transformer engineered for reliable 120V to 24V step-down applications. This foot-mounted transformer is built to handle the rigorous demands of 24Vac control circuits in both residential and commercial hardware. Featuring a 120V primary input and a 24V secondary output, it is an essential component for powering HVAC zone valves, multi-stage thermostats, and complex relay logic. The primary side utilizes 9-inch lead wires equipped with socket contacts for Amp Mate-N-Lok connectors, ensuring secure integration with existing wiring harnesses. On the secondary side, 18-inch pink and brown leads provide ample length for flexible routing within the cabinet. This unit is UL 1585 recognized and CSA certified, meeting stringent safety standards for Class 2 and Class 3 NEC compliance. Its compact footprint and wide operational temperature range of -20°F to 105°F make it a versatile replacement HVAC transformer for technicians servicing diverse equipment environments.
Technical Benefits for Contractors:
- High Power Capacity: Rated at 50VA, providing sufficient overhead for multiple low-voltage HVAC controls without voltage drop.
- Simplified Installation: Standard foot-mount design allows for quick vertical or horizontal mounting inside the air handler or control panel.
- OEM Compatibility: Pre-terminated Mate-N-Lok socket contacts facilitate a direct plug-and-play fit for many Resideo and Honeywell legacy systems.
- Durable Construction: Engineered to withstand fluctuations in line voltage while maintaining a stable 24V output to protect sensitive electronic boards.
Common Questions:
Can this transformer replace a 40VA unit?
Yes. Upgrading to a 50VA transformer provides a higher current capacity at the same voltage, which helps prevent overheating if your system has added components like humidifiers or extra zone dampers.
What is the difference between Class 2 and Class 3 compliance?
This unit is NEC compliant for both; it meets Class 2 standards for dry applications and Class 3 standards for wet applications, ensuring safety across different installation environments.
Are the lead wires pre-stripped?
The primary leads are encased in socket contacts for specific pin-and-socket housings, while the secondary leads arrive ready for wire-nut or terminal block connections.
