186D12

Power Transformers Overview

The Hammond Manufacturing 186D12 is a chassis-mount industrial power transformer with a 31.5 VA rating. It features dual primary windings for 115 VAC and 230 VAC operation at 50/60 Hz. The secondary output provides 12.6 VAC center-tapped at 2.5 A. Constructed with split bobbin design, it utilizes quick connect terminals for mounting.

Power Transformers Feature Summary

• Split bobbin construction eliminates the need for electrostatic shielding
• Dual primary winding configuration supports 115 VAC and 230 VAC input
• Chassis mount style facilitates secure installation in control panels

Power Transformers Applications

• Industrial control panel power supply
• Low voltage equipment powering
• General purpose AC to AC transformation

Power Transformers Procurement Notes

Verify that the specific order matches the 186D12 part number to ensure correct 31.5 VA rating and 12.6 VAC CT output. Confirm terminal type compatibility with existing wiring harnesses before integration into the assembly process.

Power Transformers Selection Notes

Select this model when a 31.5 VA capacity is required for chassis-mounted applications. Ensure the enclosure allows for adequate airflow around the transformer body to maintain safe operating temperatures during continuous duty cycles.

Power Transformers Part Context

This component belongs to the Hammond 186 Series of industrial power transformers. It shares the series' characteristic split bobbin architecture and dual primary winding flexibility, designed for reliable performance in standard industrial environments.

Power Transformers Replacement Considerations

The 186D10 serves as a higher current alternative within the same series, offering 10 VAC CT at 3 A with a 30 VA rating. Verify dimensional fit and electrical requirements when considering cross-series substitutions.
