376XP

Power Transformers Overview

The Hammond Manufacturing 376XP is an industrial power transformer from the 300 Series, designed for chassis mounting. It features a dual primary winding configuration supporting input voltages from 100 VAC to 240 VAC at 50 Hz or 60 Hz. The unit provides high voltage and filament outputs with a triple secondary winding arrangement. Key electrical specifications include a 171 VA power rating, a secondary voltage of 800 VAC center-tapped at 155 mA, and wire lead termination. Physical dimensions are 127 mm in length, 107.95 mm in width, and 138.17 mm in height.

Power Transformers Feature Summary

• Dual primary winding design accommodates varying input voltage ranges.
• Triple secondary winding structure supports combined high voltage and filament applications.
• Chassis mount style ensures secure installation within industrial control enclosures.

Power Transformers Applications

• Industrial control systems requiring isolated high voltage supplies
• Equipment utilizing vacuum tube filaments and plate voltages
• Test and measurement instrumentation power distribution

Power Transformers Procurement Notes

Verify that the specific order matches the 376XP model number rather than similar variants like 375XP or 378X, as these share the same series but differ in power ratings and current capacities. Confirm that the required secondary voltage and current align with the 800V CT @ 155mA specification. Ensure the chassis mounting holes and wire lead lengths meet the enclosure requirements before finalizing procurement.

Power Transformers Selection Notes

Select this component when a 171 VA rating is sufficient for the load requirements. The dual primary winding allows flexibility for different line voltages without rewiring. Consider the physical footprint of 127mm x 107.95mm x 138.17mm against available chassis space. Verify that the wire lead termination method is compatible with the downstream circuit connections.

Power Transformers Part Context

This transformer belongs to the Hammond 300 Series, which includes various models tailored for industrial applications. Models such as 370CX, 370DAX, 375XP, and 378X offer different power ratings and secondary configurations. The 376XP specifically targets applications needing moderate power with high voltage output capabilities within this standardized product family.

Power Transformers Replacement Considerations

Direct substitutes within the same series include the 375XP and 378X, though their power ratings (171VA and 237VA respectively) and current capacities differ. Ensure any replacement matches the 800V CT secondary requirement and chassis mounting dimensions. Cross-reference datasheets to confirm compatibility with existing wiring and thermal constraints.
