A41-43-28L

Power Transformers Overview

The Signal Transformer A41-43-28L is a laminated power transformer designed for chassis mounting. It features dual primary windings rated for 115 VAC and 230 VAC operation at 50/60 Hz. The dual secondary windings provide 14 VAC in parallel (3 A) or 28 VAC in series (1.5 A). With a 43 VA power rating, it offers 4000 Vrms isolation. Dimensions are 79.4 mm length, 54.4 mm width, and 68.2 mm height. Termination options include quick connects or lead wires.

Power Transformers Feature Summary

• Provides high isolation, creepage, and clearance to comply with international safety standards
• Features dual primary and dual secondary windings for flexible voltage configuration
• Constructed with a laminated core design for industrial power applications

Power Transformers Applications

• Industrial equipment requiring international safety compliance
• Chassis-mounted power supply systems
• Applications needing 4000 Vrms isolation barriers

Power Transformers Procurement Notes

Verify the specific termination style required, as the A41-43-28L designation typically indicates lead wire termination, whereas standard versions may use quick connects. Confirm RoHS compliance status and agency certifications such as UL and VDE against current manufacturer documentation before procurement. Ensure the operating temperature range of -40°C to +105°C meets system requirements.

Power Transformers Selection Notes

Select this component when chassis mounting space allows for its 79.4 mm x 54.4 mm footprint. Choose the lead wire variant if direct soldering or harness integration is preferred over quick-connect terminals. Ensure the load current does not exceed 3 A in parallel mode or 1.5 A in series mode to maintain the 43 VA rating within safe operating limits.

Power Transformers Part Context

This part belongs to the A41 International Series by Signal Transformer, designed to meet global safety standards. The series provides cost-effective solutions for industrial transformers. The 'L' suffix typically denotes the inclusion of hook-up lead wires instead of standard quick-connect terminals, facilitating easier integration into custom assemblies.

Power Transformers Replacement Considerations

The A41-43-28 is the equivalent model using quick-connect terminals instead of lead wires. Verify that the physical dimensions and pinout compatibility match the existing board layout when substituting between these variants.
