187C28

Power Transformers Overview

The Hammond Manufacturing 187C28 is an industrial control transformer designed for chassis mounting. It features a single primary winding rated for 115 VAC input and a single secondary winding providing 28 VAC center-tapped output. The unit has a power rating of 12 VA, delivering a secondary current of 0.42 A. Physical dimensions are 71.37 mm in length, 34.79 mm in width, and 41.14 mm in height. It utilizes quick connect terminals for electrical connections and operates at 50/60 Hz frequencies.

Power Transformers Feature Summary

• Chassis mount design for secure panel installation
• Single primary and single secondary winding configuration
• Quick connect terminal type for simplified wiring

Power Transformers Applications

• Industrial control panels requiring isolated low voltage power
• Equipment needing 28V AC center-tapped supply
• Chassis-mounted electronic systems

Power Transformers Procurement Notes

Verify the specific part number against official Hammond Manufacturing documentation to confirm electrical ratings and physical dimensions. Ensure compatibility with existing chassis mounting holes and terminal spacing. Confirm that the 115VAC primary voltage matches the available power source. Check for any regional compliance requirements such as RoHS status before finalizing procurement.

Power Transformers Selection Notes

Select this model when a 12 VA capacity is sufficient for the load. The 28V CT secondary is suitable for applications requiring split-phase rectification or balanced AC signals. Compare dimensions against available chassis space. Consider the 187 series family for standardized mounting if multiple units are needed. Verify terminal type compatibility with existing wiring harnesses.

Power Transformers Part Context

This component belongs to the Hammond 187 Series of industrial transformers. It shares the same chassis footprint and mounting style as other models in the series, allowing for modular design flexibility. The series offers various voltage and wattage combinations while maintaining consistent physical dimensions for specific power ranges.

Power Transformers Replacement Considerations

Check Hammond 186 series equivalents like 186C28 for dual-voltage primary options. Verify that substitute parts maintain identical mounting hole patterns and terminal configurations. Ensure replacement transformers meet the same VA rating and insulation class requirements.
