186C120

Power Transformers Overview

The Hammond Manufacturing 186C120 is a laminated core power transformer designed for chassis mounting within industrial control applications. It features dual primary windings supporting 115 VAC and 230 VAC inputs at 50 Hz or 60 Hz frequencies. The unit provides a single secondary output of 120 VAC center-tapped, delivering a rated current of 100 mA with a total power capacity of 12 VA. Physical dimensions are 71.37 mm in length, 34.79 mm in width, and 41.14 mm in height, weighing approximately 304 grams. Electrical connections utilize quick connect terminals.

Power Transformers Feature Summary

• Dual primary winding configuration allows flexible connection to either 115 VAC or 230 VAC power sources.
• Split bobbin construction design minimizes electrostatic coupling between primary and secondary circuits.
• Chassis mount style facilitates secure installation within industrial control panels and enclosures.

Power Transformers Applications

• Industrial control panel power distribution
• Equipment requiring isolated low-voltage AC power supplies
• Automation systems utilizing 120 VAC control circuits

Power Transformers Procurement Notes

Verify the specific voltage configuration required for your application before ordering. Confirm that the chassis mounting holes align with your enclosure design specifications. Ensure the 12 VA power rating meets the load requirements of the downstream circuitry. Check terminal compatibility with existing wiring harnesses to ensure proper connection via quick connect interfaces.

Power Transformers Selection Notes

Select this component when a dedicated 120 VAC center-tapped supply is needed from standard 115/230 VAC mains. Consider the physical footprint constraints against the specified dimensions. Evaluate thermal management needs based on the 12 VA continuous load. Compare against other series models if different secondary voltages or higher power ratings are required for the system architecture.

Power Transformers Part Context

This transformer belongs to the Hammond 186 Series, a line of industrial control transformers known for robust construction and standardized form factors. The series offers various secondary voltage options while maintaining consistent chassis mounting dimensions. These units are commonly specified in machinery and equipment where reliable isolation and stable voltage transformation are critical for operational safety and performance.

Power Transformers Replacement Considerations

Direct substitutes include other Hammond 186 series variants with matching electrical ratings. Verify that any replacement maintains the same chassis mounting hole pattern and overall envelope size. Ensure the new unit supports the same input voltage range and frequency specifications to guarantee compatibility with existing power infrastructure.
