Power Transformers Procurement Notes

Verify the specific datasheet version to confirm compliance with current safety standards and regulatory requirements. Ensure that the chassis mounting holes align with the design layout before procurement. Confirm that the operating environment temperature range matches the transformer's thermal ratings to prevent overheating during continuous operation.

Power Transformers Selection Notes

Select this model when a 100 VA capacity is required for industrial applications. The dual primary winding allows compatibility with both 115 VAC and 230 VAC mains voltages. The 20 VCT secondary output suits rectifier circuits requiring center-tapped connections. Chassis mounting is ideal for enclosures where space efficiency and mechanical stability are priorities.

Power Transformers Part Context

This component belongs to the DP-241 series of two-for-one transformers manufactured by Signal Transformer. The series offers various voltage configurations while maintaining consistent physical footprints. The DP-241-8-20 specifically denotes the 100 VA variant within this family, sharing design characteristics with other models in the lineup.

Power Transformers Replacement Considerations

Direct substitutes include the DP-241-8-56 for different secondary voltage requirements. Other models in the DP-241 series may serve as alternatives if power ratings or voltage outputs differ from project needs. Verify pinout and mounting hole patterns when considering cross-model replacements.
