A41-43-20

Power Transformers Overview

The Signal Transformer A41-43-20 is a laminated core power transformer designed for industrial applications. It features dual primary windings supporting 115 VAC and 230 VAC inputs at 50/60 Hz. The secondary output provides 10 VCT with configurable parallel (4.4A) or series (2.2A) connections, delivering a 43 VA rating. Dimensions are 79.4 mm length, 54.4 mm width, and 68.2 mm height. It utilizes quick connect terminals and chassis mounting.

Power Transformers Feature Summary

• Dual primary winding configuration for versatile voltage input compatibility
• Configurable secondary output allowing parallel or series connection options
• Laminated core construction optimized for standard frequency operation

Power Transformers Applications

• Industrial control systems requiring stable low-voltage power
• Servo power supply circuits
• Chassis-mounted equipment needing isolated AC power conversion

Power Transformers Procurement Notes

Verify the specific secondary configuration required for your application, as the part supports both parallel and series outputs. Confirm that the quick connect terminal type matches your wiring harness. Ensure the chassis mounting dimensions fit your enclosure constraints. Check RoHS compliance status if environmental regulations apply to your manufacturing process.

Power Transformers Selection Notes

Select this model when a 43 VA capacity is sufficient for the load. Choose between parallel or series secondary connections based on current and voltage requirements. Ensure the input voltage matches either 115 VAC or 230 VAC. Verify that the physical footprint allows for chassis installation in the target device design.

Power Transformers Part Context

This component belongs to the A41 International Series of power transformers by Signal Transformer. The series offers various power ratings and voltage configurations for industrial use. The A41-43-20 specifically addresses needs for moderate power isolation with flexible secondary output options in a compact laminated core form factor.

Power Transformers Replacement Considerations

Direct substitutes within the same series include the A41-43-515, which shares the 43 VA rating but differs in secondary voltage specifications. Ensure any replacement maintains the same primary voltage support and mounting style to preserve mechanical and electrical compatibility.
