A41-175-28L

Power Transformers Overview

The Signal Transformer A41-175-28L is a 175 VA industrial power transformer featuring dual primary windings rated for 115 VAC and 230 VAC operation. It provides dual secondary windings with a split bobbin design, delivering 14 VAC at 6.25 A in parallel or 28 VAC at 3.125 A in series configurations. The unit utilizes flange mounting and quick connect terminals with lead wires. It offers 4000 Vrms isolation voltage and complies with international safety standards including UL VW-1 flame resistance.

Power Transformers Feature Summary

• Split bobbin construction enhances electrical isolation and creepage clearance
• Dual primary and secondary windings support multiple input/output voltage configurations
• Flange mount chassis installation ensures secure mechanical stability
• Lead wires rated for high temperature environments up to +105°C

Power Transformers Applications

• Industrial control panels requiring high isolation
• Equipment needing selectable 14V or 28V secondary outputs
• Chassis-mounted power supplies for machinery
• Applications complying with strict international safety clearance standards

Power Transformers Procurement Notes

Verify the specific terminal configuration and lead wire length requirements against your assembly drawings. Confirm that the flange mounting holes align with your chassis cutouts. Ensure the operating environment temperature does not exceed the component's rated limits. Check for RoHS compliance documentation if required by your supply chain regulations. Validate that the 175 VA rating meets the peak load demands of your circuit design.

Power Transformers Selection Notes

Select this model when dual secondary flexibility is required for either 14V or 28V applications. The split bobbin design is critical for applications demanding high isolation voltages. Consider the physical dimensions and flange mounting style for chassis integration. Ensure the dual primary winding capability matches your available line voltage options. Verify that the current ratings align with the maximum load requirements of your downstream components.

Power Transformers Part Context

This component belongs to the A41 series of international standard power transformers. The series is designed to meet global safety certifications while providing robust performance in industrial settings. The A41-175-28L specifically addresses needs for higher power handling compared to lower VA variants in the same family. It represents a standard solution for chassis-mounted power conversion tasks.

Power Transformers Replacement Considerations

Direct substitutes within the A41 series include models with similar VA ratings but different secondary voltages, such as the A41-175-12. Verify that any replacement maintains the 175 VA power rating and 4000 Vrms isolation specification. Ensure the physical footprint and mounting hole patterns are compatible with existing chassis designs. Confirm that the terminal type and lead wire specifications match the original assembly requirements.
