Lennox 13H79 Transformer
The Lennox 13H79 Transformer (part number 13H7901) is a heavy-duty, foot-mount auto transformer engineered for high-voltage industrial and commercial HVAC applications. This component is specifically designed to step down voltage from a 600 VAC 60 Hz primary to a stable 460 VAC 60 Hz secondary, making it a critical part for voltage adaptation in large-scale air handlers and rooftop units. With a robust 1565 VA rating and a 3.4 Amp secondary current, this unit ensures that downstream motors and controls receive the precise power necessary for consistent performance without the risk of undervoltage failures.
Constructed with lead-style connections for secure technical integration, the Lennox 13H79 is a genuine OEM HVAC replacement part that maintains the electrical integrity of the original equipment. It is frequently utilized in systems where 575V or 600V field power must be converted to 460V to match the internal component specifications. Its 9-pound chassis providing a solid, vibration-resistant mount is built to withstand the demanding duty cycles of a commercial mechanical room. Professionals relying on HVAC voltage conversion will find this transformer provides the exact impedance and thermal stability required for long-term reliability in the field.
Key Benefits
- High-Capacity Power Conversion: Specialized 600V to 460V step-down capability with a substantial 1565 VA rating to support multiple inductive loads.
- Precision Electrical Specs: Rated at 3.4 Amps on the secondary side to ensure 460V motors operate within their intended torque and thermal parameters.
- Universal Foot Mount: Standard foot-mount transformer design allows for straightforward replacement in existing Lennox control cabinets.
- OEM Compatibility: Direct replacement for 13H7901, ensuring seamless fitment and electrical matching for Lennox commercial equipment.
Common Questions
Can I use this transformer in a 50Hz application?
No, this unit is strictly rated for 600V/480V 60Hz systems. Using it on 50Hz power can lead to overheating and core saturation due to the increased inductive reactance requirements.
How do I troubleshoot a suspected failure in the 13H79?
Check for 600V across the primary leads. If primary voltage is present but you do not see roughly 460V on the secondary, or if there is visible carbon tracking or a "burnt" odor, the windings have likely failed and the unit must be replaced.
Is this an isolation transformer or an auto transformer?
This model is an auto transformer, meaning it uses a single winding to step down voltage, which is more efficient and compact for Lennox HVAC systems requiring this specific voltage jump.
