• High isolation and creepage distance design
• Laminated core construction for standard frequency operation

Power Transformers Applications

• Industrial control systems
• Chassis-mounted electronic enclosures
• General purpose power supply input stages

Power Transformers Procurement Notes

Verify that the specific order matches the manufacturer part number A41-25-515 to ensure correct electrical specifications. Confirm that the application environment supports the thermal characteristics of a 25 VA laminated core transformer. Ensure mounting hardware is compatible with the chassis mount style and that wiring harnesses match the quick connect terminal type specified in the official datasheet.

Power Transformers Selection Notes

Select this component when a 25 VA isolated power source is required for industrial applications. The dual primary winding allows flexibility for 115 VAC or 230 VAC input regions without changing the physical unit. The specific secondary outputs of 5 V and ±15 V suit logic and analog circuit requirements. Chassis mounting is appropriate for fixed installations where space constraints align with the provided dimensions.

Power Transformers Part Context

This model belongs to the A41 series from Signal Transformer, designed for robust performance in industrial environments. The series emphasizes high isolation standards and reliable operation under standard line frequencies. The A41-25-515 variant specifically addresses needs for multiple regulated DC rails derived from a single transformer stage.

Power Transformers Replacement Considerations

Consult official cross-reference data for direct substitutes. Ensure any replacement maintains the 25 VA rating, identical pinout configuration, and chassis mounting footprint. Verify that alternative parts support the same dual primary voltage options and secondary current limits.
