167J55

Overview

The Hammond Manufacturing 167J55 is an industrial power transformer designed for low voltage applications. It features a single primary winding rated at 115 VAC and a single secondary winding providing 55 VAC center-tapped output. The unit has a power rating of 55 VA with a maximum secondary current of 2 A. It utilizes wire leads for termination and supports operation at 50 Hz or 60 Hz frequencies within a temperature range of 0°C to +130°C. The enclosure is constructed for chassis mounting, measuring 63.5 mm in length, 82.6 mm in width, and 77.7 mm in height, with a weight of approximately 1.09 kg.

Feature Summary

• Enclosed chassis mount construction for secure installation
• Dual bobbin design to minimize leakage currents
• Center-tapped secondary winding configuration
• Minimum 6-inch long wire leads for flexible connection

Applications

• Industrial control panels
• Low voltage filament circuits
• Chassis-mounted equipment power supplies

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct voltage and configuration matching. Confirm RoHS compliance status as indicated in the datasheet, noting that some listings may indicate non-compliance. Validate physical dimensions and lead lengths against the target application requirements before finalizing procurement orders.

Selection Notes

Select this component when a 55 VA capacity is required for 115 VAC input systems. Ensure the chassis mounting style and enclosed design meet environmental protection needs. Verify that the 55 VAC center-tapped output aligns with downstream circuit requirements. Consider the physical footprint and weight constraints for the intended assembly location.

Part Context

This model belongs to the Hammond 167 series of industrial control transformers. The series offers various power ratings from 25 VA to higher capacities, all sharing similar enclosed chassis-mount designs. These transformers are engineered for reliability in industrial environments, providing isolated power conversion for control circuits and low voltage loads.

Replacement Considerations

Direct substitutes include other Hammond 167 series models with identical 55 VA ratings and 55 VAC CT outputs, such as variations in ordering suffixes. Cross-manufacturer replacements require matching electrical specifications, mounting hole patterns, and thermal characteristics.
