167L55

Overview

The Hammond Manufacturing 167L55 is an industrial power transformer designed for chassis mounting. It features a laminated core construction with a single primary and single secondary winding configuration. The unit provides a power rating of 110 VA, operating at frequencies of 50 Hz or 60 Hz. Electrical specifications include a primary voltage of 115 VAC and a secondary output of 55 VAC center-tapped (CT). The secondary current rating is 2 A. Physical dimensions are 63.5 mm in length, 82.6 mm in width, and 77.7 mm in height. The device utilizes wire leads for termination and supports an operating temperature range from 0°C to +130°C.

Feature Summary

• Enclosed chassis mount design for secure installation
• Low voltage filament transformer type
• Single primary and single secondary winding architecture

Applications

• Industrial control systems
• Equipment requiring low voltage filament power
• Chassis-mounted power supply units

Procurement Notes

Verify the specific part number suffix against official Hammond Manufacturing documentation to ensure correct electrical ratings and physical dimensions. Confirm that the required voltage, current, and frequency specifications match the application requirements before procurement. Check for RoHS compliance status as indicated in the manufacturer's datasheet. Ensure the chassis mounting style and wire lead termination are compatible with the target enclosure design.

Selection Notes

Select this component when a 110 VA power rating is required for industrial applications. The 115 VAC primary input must align with the available line voltage. The 55 VAC CT secondary output determines the available DC voltage after rectification. Consider the physical footprint of 63.5 x 82.6 x 77.7 mm for enclosure space planning. Verify thermal management capabilities given the maximum operating temperature of +130°C.

Part Context

This transformer belongs to the Hammond 167 series, which encompasses various industrial power transformers. The series includes models with different power ratings and voltage configurations, all sharing similar enclosed chassis mount designs. The 167L55 specifically addresses needs for moderate power levels with a center-tapped secondary output.

Replacement Considerations

Consult Hammond Manufacturing cross-reference guides for direct substitutes within the 167 series. Verify that any replacement maintains identical electrical parameters including 110 VA rating, 115 VAC primary, and 55 VAC CT secondary. Ensure physical dimensions and mounting styles remain compatible with existing chassis layouts.
