266L12

Power Transformers Overview

The Hammond Manufacturing 266L12 is a chassis-mount industrial power transformer with a 31.5 VA rating. It features dual primary windings for 115 VAC and 230 VAC inputs, supporting 50 Hz/60 Hz frequencies. The secondary output provides 12.6 VAC center-tapped at 2.5 A or 6.3 VAC at 5 A via wire leads. Dimensions are 93.72 mm length, 55.88 mm width, and 58.67 mm height. Operating temperature ranges from 0°C to +130°C.

Power Transformers Feature Summary

• Dual primary winding configuration enables compatibility with both 115 VAC and 230 VAC input standards.
• Center-tapped secondary design allows flexible voltage selection between 12.6 VAC and 6.3 VAC outputs.
• Chassis mount style with wire lead termination facilitates direct integration into control panels.

Power Transformers Applications

• Industrial control panel power distribution
• Equipment requiring low voltage filament supply
• General purpose AC power conversion in machinery

Power Transformers Procurement Notes

Verify the specific secondary current requirement matches the application load before ordering. Confirm that the chassis mounting holes align with the provided dimensional specifications. Ensure the operating environment stays within the 0°C to +130°C temperature range. Check for RoHS compliance requirements if applicable to your region. Review the datasheet for insulation class and isolation voltage ratings.

Power Transformers Selection Notes

Select this model when a 31.5 VA capacity is sufficient for the load. Choose based on the need for dual primary voltage flexibility without external switching. Consider the physical dimensions for enclosure space constraints. Evaluate the wire lead termination against available connection methods. Compare against other 266 series variants if different voltage or power levels are needed.

Power Transformers Part Context

This component belongs to the Hammond 266 Series of industrial control transformers. These units are designed for robust performance in demanding environments. The series offers various power ratings and voltage configurations. The 266L12 specifically addresses needs for moderate power with versatile secondary options.

Power Transformers Replacement Considerations

Check Hammond part numbers like 266N12 for higher current capacity or 266G20 for lower power needs. Verify that any substitute maintains the same chassis mounting footprint and terminal type. Ensure electrical ratings meet or exceed original specifications.
