A41-25-28L

Power Transformers Overview

The Signal Transformer A41-25-28L is a laminated core power transformer rated at 25VA. It features dual primary windings supporting 115V and 230V inputs in parallel configuration, and dual secondary windings providing 14V and 28V outputs in series or parallel arrangements. The unit delivers up to 1.86A in parallel mode and 900mA in series mode. It offers 4000Vrms isolation voltage and utilizes lead wire termination for chassis mounting.

Power Transformers Feature Summary

• Provides high isolation, creepage, and clearance distances to comply with international safety standards.
• Features a laminated core design for efficient power transformation.
• Supports flexible output configurations through dual secondary windings.

Power Transformers Applications

• Industrial equipment requiring isolated power supplies
• Medical devices needing compliant isolation barriers
• General purpose AC to DC power conversion systems

Power Transformers Procurement Notes

Verify the specific datasheet version (ST-A41-L) against your design requirements before ordering. Confirm that the lead wire termination style matches your assembly process. Ensure the chassis mounting dimensions are compatible with your enclosure design. Check RoHS compliance status if required by your supply chain regulations. Validate the 4000Vrms isolation rating meets your safety certification needs.

Power Transformers Selection Notes

Select this component when a 25VA capacity is sufficient for the load. Choose the A41-25-28L specifically for its 14V/28V secondary options. Consider the physical size of 71.40mm x 54.40mm for spatial constraints. Evaluate the need for dual primary input flexibility across 115V and 230V regions. Assess whether the lead wire termination is preferable over PCB pins for your manufacturing workflow.
