167N80

Overview

The Hammond Manufacturing 167N80 is an industrial power transformer designed for low voltage applications. It features a laminated core construction with a single primary winding rated at 115 VAC and a single secondary winding providing 80 VAC center-tapped output. The unit has a power rating of 320 VA and supports a maximum secondary current of 4 A. It operates at frequencies of 50 Hz or 60 Hz and utilizes wire leads for termination. The transformer is enclosed and intended for chassis mounting, with physical dimensions of approximately 114.3 mm in length, 114.3 mm in width, and 114.3 mm in height.

Feature Summary

• Enclosed chassis mount design for secure installation
• Laminated core construction for efficient power transfer
• Single primary and single secondary winding configuration
• Center-tapped secondary output for versatile circuit integration

Applications

• Industrial control panels requiring isolated power sources
• Low voltage filament heating circuits
• Equipment needing 80VAC center-tapped supply
• Chassis-mounted power distribution systems

Procurement Notes

Verify the specific datasheet version to confirm RoHS compliance status and exact lead times, as these parameters may vary by production batch and region. Ensure that the required wire lead length meets the mechanical constraints of the target enclosure. Cross-reference the 115 VAC primary input with the available facility power to prevent mismatch issues during installation.

Selection Notes

Select this model when a 320 VA capacity is required within a standard chassis footprint. The 80 VAC center-tapped output is suitable for rectifier bridges or dual-rail supplies. Consider the enclosed type for environments where dust protection is necessary. Verify that the 4 A secondary current rating exceeds the peak load requirements of the connected equipment to ensure reliable operation under full load conditions.

Part Context

The 167N80 belongs to the Hammond 167 series of industrial power transformers. This series is characterized by enclosed designs and chassis mounting options, distinguishing it from open-frame variants. The 167 series provides a range of power ratings and voltage configurations to support various industrial control and power supply applications, offering a standardized form factor for system designers.

Replacement Considerations

Direct substitutes within the same series include models with similar power ratings and voltage outputs, such as the 167N70 (280VA, 70VCT) or 167P18 (90VA, 18VCT), though electrical specifications differ. When replacing, verify that the new part matches the mounting hole pattern and terminal spacing. No other specific cross-referenced part numbers are confirmed in public documentation.
