A41-25-20

Power Transformers Overview

The A41-25-20 is a laminated core industrial power transformer with a 25 VA rating. It features dual primary windings supporting 115 VAC and 230 VAC inputs at 50/60 Hz. The secondary configuration provides parallel 10 VAC at 2.5 A maximum current, or series 20 VAC at 1.25 A maximum current. Designed for chassis mounting, the unit measures 71.4 mm in length, 54.4 mm in width, and 58.7 mm in height. Electrical connections are established via quick connect terminals.

Power Transformers Feature Summary

• Dual primary winding capability for flexible 115 VAC or 230 VAC input selection
• Configurable secondary output allowing parallel 10 VAC or series 20 VAC operation
• Chassis mount design with quick connect termination style

Power Transformers Applications

• Industrial control panels requiring isolated power supply
• Equipment utilizing 10 VAC or 20 VAC secondary circuits
• General purpose AC to AC voltage transformation in machinery

Power Transformers Procurement Notes

Verify that the required secondary configuration matches the application needs, as the A41-25-20 supports both parallel and series outputs. Confirm input voltage compatibility with the dual primary winding specification. Ensure mechanical fit within the chassis enclosure based on the specified dimensions. Check terminal type requirements against the quick connect standard.

Power Transformers Selection Notes

Select this component when a 25 VA capacity is sufficient for the load. Choose this model if the system requires either 10 VAC or 20 VAC secondary voltage derived from a single transformer unit. Consider the physical constraints of the chassis mount form factor. Evaluate the need for dual primary winding flexibility for international voltage standards.

Power Transformers Part Context

This part belongs to the A41 series of international transformers manufactured by Signal Transformer. The series offers various power ratings and voltage configurations. The A41-25-20 specifically addresses applications needing moderate power isolation with selectable secondary voltages. It serves as a standard solution for industrial control power distribution.

Power Transformers Replacement Considerations

Direct substitutes include other A41 series models with identical 25 VA ratings and compatible voltage outputs. Verify pinout and dimension compatibility before swapping. Models like A41-25-24 offer different secondary voltages but share the same form factor.
