A41-80-20

Power Transformers Overview

The Signal Transformer A41-80-20 is an industrial power transformer with an 80 VA rating. It operates at 50/60 Hz and features dual primary windings for 115 VAC or 230 VAC input. The secondary configuration provides a 20 VCT output at 4.0 A, along with a 10 V tap at 8.0 A. Designed for chassis mounting, it utilizes quick connect terminals and solder lugs. The unit measures 63.5 mm in length, 64.3 mm in width, and 77.7 mm in height, ensuring compatibility with standard industrial control panel layouts.

Power Transformers Feature Summary

• Dual primary winding capability supports flexible voltage selection between 115 VAC and 230 VAC inputs.
• Secondary circuit offers multiple output taps including a center-tapped 20 VCT configuration and a dedicated 10 V auxiliary tap.
• Robust construction designed for industrial environments with Class F-1 insulation system.

Power Transformers Applications

• Industrial control panels requiring isolated power distribution
• Machinery systems utilizing 115 VAC or 230 VAC mains supply
• Equipment needing separate 10 V control circuit power

Power Transformers Procurement Notes

Verify the specific terminal type requirements against the datasheet, as configurations may include both quick connects and solder lugs. Confirm that the 80 VA load does not exceed the rated capacity of the secondary windings during operation. Ensure the installation environment accommodates the specified physical dimensions and chassis mounting style.

Power Transformers Selection Notes

Choose this model when a single transformer must provide both main secondary power and a lower voltage auxiliary tap. The dual primary design simplifies inventory management for global deployments by supporting different input voltages. Verify that the required current ratings for both the 20 VCT and 10 V outputs are within the component's specifications.

Power Transformers Part Context

This component belongs to the A41 series of international power transformers manufactured by Signal Transformer. The series is characterized by laminated core construction and standardized footprints. The A41-80-20 variant specifically addresses applications requiring moderate power levels with versatile secondary output options for complex control logic.

Power Transformers Replacement Considerations

Direct substitutes within the same series include the A41-130-20 for higher power requirements. Cross-reference pinout and mounting hole patterns when considering alternative manufacturers to ensure mechanical compatibility without redesigning the chassis.
