Power Transformers Procurement Notes

Verify the specific datasheet version from Bel Signal Transformer to confirm terminal orientation and insulation class ratings. Ensure the application environment temperature aligns with the transformer's thermal specifications. Confirm that the chassis mounting holes match the mechanical dimensions provided in the official documentation before integration.

Power Transformers Selection Notes

Select this model when a 25 VA capacity is required with flexible secondary voltage options. The dual primary design accommodates both 115 V and 230 V mains without rewiring. Consider the physical dimensions of 79.4 mm by 79.7 mm for enclosure space planning. Verify that the quick connect terminals are compatible with the existing wiring harness or PCB layout.

Power Transformers Part Context

This component belongs to the A41 international series of power transformers manufactured by Signal Transformer. The series offers various power ratings and voltage configurations tailored for industrial applications. The A41-25-28 specifically addresses needs for moderate power isolation with configurable secondary outputs, fitting within the broader portfolio of laminated core transformers designed for reliability.

Power Transformers Replacement Considerations

Cross-reference part numbers such as A41-43-28 for higher power requirements or A41-130-24 for increased capacity. Ensure replacement units maintain the same 25 VA rating and secondary voltage characteristics. Verify that mechanical mounting patterns and terminal types remain identical to avoid redesigning the chassis interface.
