162J28-BULK

Overview

The Hammond Manufacturing 162J28-BULK is a laminated core power transformer designed for through-hole mounting. It features dual primary windings rated for 115V and 230V operation, providing versatile input compatibility. The secondary configuration offers parallel output of 14V at 2.6A or series output of 28V at 1.3A, delivering a maximum power rating of 36VA. This component includes a 2500Vrms isolation voltage for safety. Physical dimensions are 66.68mm in length, 55.55mm in width, with a maximum installation height of 39.70mm. It weighs approximately 499g.

Feature Summary

• Dual primary winding design supports both 115V and 230V AC input sources.
• Flexible secondary output allows switching between parallel low-voltage/high-current or series high-voltage/lower-current configurations.
• Laminated core construction provides efficient magnetic coupling for standard power applications.

Applications

• Industrial control panel power supplies
• Test and measurement equipment internal power systems
• General purpose electronic device power conversion

Procurement Notes

Verify the specific suffix requirement when ordering; the bulk packaging designation indicates loose component supply rather than tape-and-reel or boxed formats. Confirm that the receiving facility has appropriate handling procedures for heavy, individually packaged transformers. Ensure that the procurement documentation explicitly references the full part number to distinguish it from non-bulk variants within the same electrical specification family.

Selection Notes

Select this model when a robust 36VA transformer is required for chassis-mounted installations using through-hole pins. The dual primary capability simplifies global deployment without needing separate SKUs for different grid voltages. Consider the physical footprint and weight constraints, as the laminated core design results in a heavier profile compared to modern switched-mode alternatives. Verify that the enclosure space accommodates the specified maximum height and dimensional requirements.

Part Context

This component belongs to the Hammond 162 series of general-purpose power transformers. It is functionally similar to the 162J28 but differs in packaging format. The series is characterized by traditional laminated core technology, offering reliable isolation and linear power delivery suitable for sensitive analog circuits or standard digital logic powering where ripple performance is critical.

Replacement Considerations

The Signal Transformer DST-7-28 is documented as a similar replacement option. Verify pinout compatibility and mechanical mounting hole alignment before substitution. Ensure the alternative part meets the same 36VA power rating and 2500Vrms isolation requirements to maintain system safety standards.
