229D20R-BULK

Power Transformers Overview

The Hammond Manufacturing 229D20R-BULK is a low-profile, PCB mount power transformer with a 6 VA rating. It features dual primary windings rated for 115 VAC and 230 VAC input, and a dual secondary winding providing 20 VAC center-tapped output at 300 mA (or 10 VAC at 600 mA). Designed for through-hole solder pin termination, the unit measures 47.75 mm in length, 39.62 mm in width, and 21.59 mm in height. It operates within a temperature range of 0°C to +130°C at 50/60 Hz frequencies.

Power Transformers Feature Summary

• Dual primary winding configuration supports flexible 115 VAC or 230 VAC input selection.
• Low profile design facilitates compact integration into printed circuit board assemblies.
• Center-tapped secondary output enables versatile rectification and voltage regulation circuits.

Power Transformers Applications

• Low voltage AC power supply modules
• Control panel interface circuits
• Industrial instrumentation power stages

Power Transformers Procurement Notes

Verify that the specific suffix 'BULK' aligns with your required packaging format, as standard distribution often utilizes individual retail units. Confirm that the lead time and factory production schedule meet your project requirements before finalizing orders. Ensure the component meets all necessary RoHS compliance standards for your target market regulations.

Power Transformers Selection Notes

Select this model when space constraints require a low-profile form factor alongside a 6 VA power capacity. The dual primary winding allows compatibility with both 115 VAC and 230 VAC mains without rewinding. Ensure the PCB layout accommodates the specified through-hole pin spacing and physical dimensions for proper mechanical mounting.

Power Transformers Part Context

This component belongs to the Hammond 229 series of power transformers, which are engineered for general-purpose applications requiring reliable isolation and voltage transformation. The series emphasizes compactness and efficiency for embedded electronic systems. The 229D20R-BULK variant specifically denotes the bulk packaging option for this particular electrical specification.

Power Transformers Replacement Considerations

Consult official Hammond Manufacturing documentation for cross-reference data. Verify that any substitute part matches the 6 VA rating, 20 VAC CT secondary output, and physical footprint constraints to ensure functional compatibility.
