167M28

Overview

The Hammond Manufacturing 167M28 is a laminated core power transformer designed for chassis mounting. It features a single primary winding rated at 115V and a single secondary winding providing 28V at 3A, resulting in an 84VA power rating. The unit measures 63.50mm in length and 76.20mm in width, with a maximum installation height of 77.72mm. It offers 2000Vrms isolation voltage and utilizes wire leads for termination. The component is RoHS compliant and classified under ECCN EAR99.

Feature Summary

• Chassis mount design with wire lead termination
• Laminated core construction for efficient power transformation
• Single primary to single secondary winding configuration

Applications

• Industrial machinery control circuits
• Electrical equipment power distribution
• Renewable energy system components

Procurement Notes

Verify the specific voltage and current requirements against the 115V primary and 28V/3A secondary specifications before procurement. Confirm that the chassis mounting style and physical dimensions align with the enclosure design. Ensure compliance with local regulatory standards such as RoHS and UL508A where applicable. Check for any specific environmental operating temperature constraints defined in the official datasheet.

Selection Notes

Select this model when a compact, chassis-mounted solution is required for stepping down 115VAC to 28VAC. The 84VA rating suits moderate load applications within industrial or renewable energy contexts. Consider the physical footprint of 63.50mm x 76.20mm for panel layout planning. Verify that the 2000Vrms isolation meets safety requirements for the intended electrical environment.
