Reznor 103498 Transformer

The Reznor 103498 Transformer is a heavy-duty control component precision-engineered for commercial and industrial HVAC voltage step-down applications. This 41VA transformer is specifically designed to convert a high-voltage 480V primary input down to a stable 24V secondary output, ensuring safe and consistent power delivery to critical control circuits. As a genuine OEM Reznor replacement part, it maintains the precise electrical load balance required for the integrated operation of thermostats, ignition modules, and limit switches.

This step-down transformer is built to the rigorous standards of veteran technicians, featuring high-quality windings and core materials that deliver 41VA rated capacity for continuous duty. Primarily utilized in Reznor duct furnaces such as the RBHA, RBA, and RBL models, it ensures that your low-voltage relays and dampers function without the risk of voltage drops or core saturation. The compact footprint allows for a seamless fit within existing electrical compartments, facilitating rapid field replacement during routine maintenance or system retrofits.

Key Benefits

• Optimized 480V to 24V conversion specifically tuned for industrial heating control systems.
• 41VA power rating provides ample headroom for driving multiple low-voltage relays and damper actuators simultaneously.
• Direct OEM compatibility with Reznor RBHA, RBA, and RBL series duct furnaces ensures proper mounting and terminal alignment.
• High-grade control and damper transformer construction minimizes thermal rise and electromagnetic interference in sensitive HVAC circuits.
• Simplifies the HVAC control circuit power supply, replacing legacy 40VA units with a more robust, modern equivalent.

Common Questions

What happens if I use a 40VA transformer instead of this 41VA model?
While the difference is minimal, the 41VA capacity of the 103498 provides a slight increase in current-handling capability. Stick with the 103498 to ensure the total VA load of your relays and controllers doesn't exceed the transformer's saturation point, which can lead to overheating or erratic control behavior.

Is the Reznor 103498 compatible with 460V systems?
Yes. In most industrial applications, 460V and 480V are used interchangeably for these types of step-down transformers, as the component is designed to handle standard industrial line voltage fluctuations common in broad-grid 480V systems.

Can I use this transformer for non-Reznor equipment?
Technically, this is a universal 480V/24V control transformer, but it is specifically optimized for Reznor unit heaters. Verify the mounting footprint and terminal requirements if applying it to a third-party air handler or boiler system.
