167J28

Overview

The Hammond Manufacturing 167J28 is a low voltage enclosed power transformer designed for chassis mounting. It features a laminated core construction with a single primary winding rated at 115V and a single secondary winding providing 28VCT (Center Tap). The unit has a maximum power rating of 28VA, supporting an output current of 1A. It offers 2000Vrms isolation voltage between windings. The component weighs approximately 1.3 lbs (0.59 kg) and utilizes wire leads for termination.

Feature Summary

• Enclosed chassis mount design for industrial applications
• Laminated core construction for efficient power transformation
• Single primary to single center-tapped secondary configuration
• High isolation voltage rating for safety

Applications

• Filament power supply circuits
• Low voltage rectifier systems
• Industrial control panel power distribution

Procurement Notes

Verify the specific datasheet version when ordering, as manufacturing revisions may occur. Confirm that the 115V primary input matches your system voltage. Ensure the chassis mounting holes align with your enclosure design prior to installation. Check for RoHS compliance status if required by your project specifications.

Selection Notes

Select this model when a compact, enclosed transformer is needed for low voltage applications requiring center tap functionality. Compare against the 167M28 if higher power capacity (84VA) is required for similar voltage ratings. Consider the physical dimensions and weight constraints of the target chassis before finalizing the selection.

Part Context

This component belongs to the Hammond 167 series of general-purpose power transformers. The series offers various VA ratings and voltage configurations. The 167J28 specifically addresses needs for 28VA applications with a 28VCT secondary output, fitting into the broader range of enclosed chassis-mount transformers offered by the manufacturer.

Replacement Considerations

The 167M28 is a confirmed substitute within the same series offering identical 28VCT secondary voltage but with increased 84VA power capacity. Verify that the higher VA rating does not cause thermal issues in confined spaces.
