A41-43-16L

Power Transformers Overview

The Signal Transformer A41-43-16L is a laminated core power transformer with a 43 VA rating, designed for chassis mounting. It features dual primary windings supporting 115V and 230V inputs at 50/60 Hz. The secondary configuration provides parallel 8V output at up to 5.4A or series 16V output at 2.7A. Key electrical specifications include a 4000Vrms isolation voltage and lead wire termination. Physical dimensions are 79.40mm in length, 54.40mm in width, and a maximum seated height of 68.20mm.

Power Transformers Feature Summary

• Provides high isolation, creepage, and clearance distances to comply with international safety standards.
• Features dual primary and dual secondary windings for flexible input and output configurations.
• Constructed with a laminated core design optimized for industrial power applications.

Power Transformers Applications

• Industrial control systems requiring isolated power supplies
• Equipment needing compliance with international safety regulations
• Chassis-mounted power distribution units

Power Transformers Procurement Notes

Verify the specific suffix 'L' indicates standard lead wire length and color as per manufacturer documentation. Confirm that the required output current does not exceed the rated parallel 5.4A or series 2.7A limits. Ensure the installation environment supports the operating temperature range of -40°C to +105°C. Check for RoHS compliance status if restricted substances are a concern for your assembly process.

Power Transformers Selection Notes

Select this model when a 43 VA capacity is sufficient for the load requirements. Choose the parallel 8V configuration for higher current needs or series 16V for higher voltage applications. Ensure the chassis mounting holes align with the physical footprint of 79.40mm by 54.40mm. Verify that the 4000Vrms isolation meets the safety requirements of the target equipment design.

Power Transformers Part Context

This component belongs to the A41 Series of international transformers from Signal Transformer. The series is engineered to meet global safety certifications including UL, CSA, and VDE. These transformers are widely used in industrial sectors where reliable isolation and standardized form factors are critical for system integration and regulatory approval.

Power Transformers Replacement Considerations

The A41-43-16 is a related variant with identical electrical ratings but may differ in lead wire specifications. Verify that any substitute part maintains the same 43 VA rating, 115/230V primary input, and compatible physical dimensions for chassis mounting.
