167T22

Power Transformers Overview

The Hammond Manufacturing 167T22 is a low voltage filament rectifier power transformer designed for industrial applications. It features a single primary winding rated at 115 VAC and a single secondary winding providing 22 VAC center-tapped output. The unit has a power rating of 440 VA with a secondary current rating of 20 A. It utilizes an enclosed chassis mount style with wire leads for termination. Physical dimensions are 95.3 mm in length, 127 mm in width, and 115.8 mm in height.

Power Transformers Feature Summary

• Enclosed chassis mount construction with dual bobbin design eliminating the need for electrostatic shields
• Low voltage filament rectifier configuration with center-tapped secondary winding
• Minimum six-inch long wire leads for flexible installation

Power Transformers Applications

• Industrial automation control circuits
• Filament heating for vacuum tubes or similar components
• Rectifier circuit power supply stages

Power Transformers Procurement Notes

Verify the exact power rating specification as sources indicate both 264 VA and 440 VA values; confirm the specific datasheet version required for your design. Ensure chassis mounting holes align with your enclosure specifications. Check shipping restrictions as some distributors limit transport to USD-only regions due to size or weight constraints. Confirm lead times directly with suppliers as availability may vary significantly.

Power Transformers Selection Notes

Select this component when a robust, enclosed transformer is needed for low voltage filament or rectifier applications requiring high current capacity. The chassis mount style simplifies integration into existing industrial panels. Verify that the 115 VAC primary input matches your system voltage. Consider the physical footprint of 95.3 x 127 x 115.8 mm during mechanical design. Ensure the 20 A secondary current rating meets the load requirements of the connected circuitry.

Power Transformers Part Context

This model belongs to the Hammond 167 Series of power transformers, which are engineered for industrial environments. The series typically offers enclosed designs suitable for chassis mounting. Similar models in the 165 and 265 series share comparable form factors but may differ in electrical ratings or winding configurations. These transformers are commonly used in heavy-duty equipment where reliability and thermal management are critical.

Power Transformers Replacement Considerations

Consult official Hammond Manufacturing documentation for direct cross-references. Verify that any substitute part matches the 115 VAC primary, 22 VAC CT secondary, and 440 VA (or verified 264 VA) rating. Ensure physical dimensions and mounting hole patterns are compatible with the existing chassis. Confirm that the replacement maintains the enclosed construction and wire lead termination style.
