186C28

Power Transformers Overview

The Hammond Manufacturing 186C28 is a chassis-mount industrial control transformer with a 12 VA power rating. It features dual primary windings for 115 VAC and 230 VAC input at 50/60 Hz. The secondary provides a single 28 VAC center-tapped output at 0.42 A. Dimensions are 71.37 mm length, 34.79 mm width, and 41.14 mm height. Termination uses quick connects.

Power Transformers Feature Summary

• Chassis mount design for secure panel installation
• Dual primary winding configuration supports multiple input voltages
• Center-tapped secondary output enables split voltage applications

Power Transformers Applications

• Industrial control panels requiring low voltage isolation
• Equipment needing 28V AC power for control circuits
• Chassis-mounted power distribution systems

Power Transformers Procurement Notes

Verify the specific terminal type required for your application, as some variants in this series may offer combination solder or quick connect options. Confirm that the 12 VA rating meets the load requirements of your secondary circuit to prevent overheating. Ensure the chassis mounting holes align with your enclosure specifications before ordering.

Power Transformers Selection Notes

Select this model when a 12 VA capacity is sufficient for the control circuit. The 28V CT secondary is suitable for applications requiring balanced positive and negative rails from a transformer source. Consider the physical dimensions to ensure fit within the designated chassis space compared to higher or lower wattage alternatives.

Power Transformers Part Context

This component belongs to the Hammond 186 Series, which focuses on low-voltage industrial transformers. It shares similar chassis mounting characteristics and dual-primary flexibility with other models in the series, such as the 186C24 and 186C56, differing primarily in secondary voltage and current ratings.

Power Transformers Replacement Considerations

The Hammond 186C24 (24V CT) and 186C56 (56V CT) are direct mechanical substitutes within the same series but have different electrical outputs. Verify that the replacement matches the required secondary voltage and current for the specific circuit design.
