185D10

Power Transformers Overview

The Hammond Manufacturing 185D10 is a laminated core power transformer designed for chassis mounting. It features dual primary windings rated for 115 VAC and 230 VAC operation at 50 Hz or 60 Hz. The secondary configuration provides a single winding with center tap, delivering 10 VAC at 4.3 A (43 VA total rating). Electrical isolation is rated at 4000 Vrms. Physical dimensions are 56.39 mm in length, 79.25 mm in width, and 68.07 mm in height. Termination is achieved via quick connect terminals.

Power Transformers Feature Summary

• Dual primary winding design enables flexible voltage selection between 115 VAC and 230 VAC.
• Center-tapped secondary output supports rectifier applications requiring split voltage rails.
• Chassis mount construction ensures secure installation within industrial control enclosures.

Power Transformers Applications

• Industrial control systems requiring low voltage power distribution
• Rectifier circuits utilizing center-tapped transformer configurations
• Chassis-mounted equipment needing isolated power supply stages

Power Transformers Procurement Notes

Verify the specific suffix of the part number when ordering, as variations such as 'BULK' may indicate different packaging formats rather than electrical changes. Confirm that the required current rating of 4.3 A meets the load requirements of the target circuit. Ensure the chassis mounting holes align with the physical dimensions provided in the datasheet to facilitate proper integration into the enclosure design.

Power Transformers Selection Notes

Select this component when a 43 VA capacity is sufficient for the application's power needs. The dual primary winding allows compatibility with both standard North American and international line voltages without rewiring. The quick connect termination style simplifies assembly compared to soldered connections. Consider the physical footprint of approximately 56 x 79 mm to ensure adequate space within the equipment housing.

Power Transformers Part Context

This transformer belongs to the Hammond 185 series, which offers various power ratings and voltage configurations. Similar models in the series include the 185D16 and 185D20, which provide higher voltages but lower currents. The 185E10 represents a higher power variant within the same family. These components share common mounting styles and termination types, facilitating standardized design approaches across different power requirements.

Power Transformers Replacement Considerations

Direct substitutes include other Hammond 185 series transformers with matching 43 VA ratings and 10V CT secondary outputs. Verify that any replacement maintains the 4000 Vrms isolation rating and compatible physical dimensions for chassis mounting. Cross-reference terminal spacing to ensure quick connect pins align with existing PCB or wiring harness layouts.
