187B20-BULK

Power Transformers Overview

The Hammond Manufacturing 187B20-BULK is an industrial power transformer from the 186-187 series, designed for chassis mounting. It features a single primary winding rated at 115 VAC and a single secondary winding providing 20 VAC center-tapped output at 300 mA. The unit has a power rating of 6 VA and utilizes quick connect terminals for electrical interfacing. Physical dimensions are 60.2 mm in length, 31.75 mm in width, and 34.79 mm in height.

Power Transformers Feature Summary

• Chassis mount design for secure panel integration
• Single primary and single secondary winding configuration
• Quick connect terminal type for simplified wiring

Power Transformers Applications

• Industrial control panels
• Low voltage power supply circuits
• Equipment requiring isolated AC power conversion

Power Transformers Procurement Notes

Verify that the specific bulk packaging variant matches your assembly requirements. Confirm that the 115 VAC primary rating aligns with your local mains supply standards. Ensure the chassis mounting holes correspond to your enclosure design. Check that the quick connect terminal spacing fits your PCB or wire harness layout. Validate RoHS compliance status if required by your manufacturing regulations.

Power Transformers Selection Notes

Select this component when a compact, low-voltage isolation transformer is needed for industrial applications. The 6 VA rating suits light loads such as relay coils or small circuitry. Consider the physical footprint against available chassis space. Verify that the center-tapped secondary meets the voltage requirements of downstream components. Ensure the operating temperature range covers your environmental conditions.

Power Transformers Part Context

This part belongs to the Hammond 186-187 series of general-purpose power transformers. These units are widely used in industrial equipment for stepping down line voltage to safer levels. The series offers various voltage configurations while maintaining consistent mechanical dimensions for interchangeability within the same power class.

Power Transformers Replacement Considerations

Direct substitutes include other Hammond 187 series models with identical 6 VA ratings and chassis mounting profiles, such as the 187B120 or 187B16, provided their secondary voltage specifications match the application needs. Cross-brand replacements must be verified for equivalent electrical parameters and mechanical fit.
