A41-80-28

Power Transformers Overview

The Signal Transformer A41-80-28 is an 80 VA single-phase laminated core power transformer designed for industrial applications. It features dual primary windings supporting 115 VAC and 230 VAC inputs at 50/60 Hz frequencies. The secondary configuration provides a center-tapped 28 V output with current ratings of 2.8 A in series mode or 5.6 A in parallel mode. Constructed for chassis mounting, the unit measures 63.5 mm in length, 64.3 mm in width, and 77.7 mm in height, weighing approximately 1.27 kg. Connections are made via quick connect terminals.

Power Transformers Feature Summary

• Dual primary winding architecture enables flexible input voltage selection between 115 VAC and 230 VAC.
• Center-tapped secondary design allows for configurable series or parallel output connections.
• Laminated core construction ensures stable performance across standard 50 Hz and 60 Hz frequency ranges.

Power Transformers Applications
