266LA12

Power Transformers Overview

The Hammond Manufacturing 266LA12 is a laminated core power transformer designed for chassis mounting. It features dual primary windings rated for 117 VAC and 234 VAC at 50/60 Hz. The secondary configuration provides 12 VAC at 2 A or 6 VAC at 4 A, delivering a total power rating of 24 VA. This industrial control transformer utilizes wire leads for termination and operates within a temperature range of 0°C to +130°C.

Power Transformers Feature Summary

• Dual primary winding capability allows operation with both 117 VAC and 234 VAC input sources.
• Dual secondary windings offer flexible connection options, supporting center-tapped or individual configurations.
• Laminated core construction ensures stable performance for low voltage filament applications.

Power Transformers Applications

• Industrial control panel power supply
• Chassis-mounted equipment integration
• Low voltage filament circuit powering

Power Transformers Procurement Notes

Verify the specific datasheet version to confirm RoHS compliance status and exact dimensional tolerances before finalizing procurement. Ensure that the required insulation class and thermal protection ratings align with the target enclosure's safety standards. Confirm wire lead lengths and gauge specifications match the assembly requirements to prevent installation issues.

Power Transformers Selection Notes

Select this model when a 24 VA capacity is required for chassis-mounted installations. The dual primary design simplifies global deployment by accommodating standard 115V and 230V regions without separate part numbers. Verify that the physical dimensions fit the available chassis space and that the wire lead termination method suits the existing wiring harness.

Power Transformers Part Context

This component belongs to the Hammond 266 series of industrial power transformers. The series is characterized by laminated core construction and chassis mounting styles. Other models in the family vary primarily in power rating and secondary voltage outputs while maintaining similar form factors and dual primary input capabilities.

Power Transformers Replacement Considerations

Cross-reference with Hammond 266L12 for higher power needs or 266J26 for different voltage ratios. Ensure substitute parts maintain the same chassis mounting footprint and wire lead termination style to avoid mechanical redesign.
