A41-43-28

Power Transformers Overview

The Signal Transformer A41-43-28 is a laminated power transformer designed for industrial applications. It features dual primary windings rated for 115 VAC and 230 VAC, and dual secondary windings providing 28 VCT at 1.5 A or 14 V at 3 A. The unit has a power rating of 43 VA and operates at 50/60 Hz. Dimensions are 79.4 mm in length, 54.4 mm in width, and 68.2 mm in height. Termination is via quick connects, with chassis mounting style.

Power Transformers Feature Summary

• Dual primary winding configuration supports multiple input voltage standards
• Dual secondary winding design enables flexible output voltage options
• Laminated core construction ensures stable performance at standard frequencies

Power Transformers Applications

• Industrial control systems requiring isolated power
• Servo drive power supplies
• Equipment needing 115V/230V AC input compatibility

Power Transformers Procurement Notes

Verify the manufacturer designation carefully, as this component is often listed under Bel Signal Transformer or Pulse due to corporate acquisitions. Confirm the specific suffix matches the required voltage and current ratings. Ensure the datasheet version aligns with the intended frequency range of 50/60 Hz. Cross-reference the termination type to guarantee compatibility with existing circuit board layouts.

Power Transformers Selection Notes

Select this model when dual secondary outputs are necessary for different logic or drive voltages within a single enclosure. The chassis mount style requires adequate panel space and clearance for heat dissipation. Verify that the 43 VA rating meets the total load requirements of all connected circuits. Consider the physical dimensions against available mounting areas in the final assembly design.

Power Transformers Part Context

This component belongs to the International Series transformers, designed for global compatibility with varying input voltage standards. It serves as a critical isolation stage in power distribution networks for industrial machinery. The series emphasizes robust construction and reliable performance in demanding environments.

Power Transformers Replacement Considerations

Direct substitutes may include other models from the same A41 series with matching VA ratings. Verify pinout compatibility before swapping. Alternative brands may offer similar specifications but require mechanical fit verification.
