14A-10R-10

Overview

The Signal Transformer 14A-10R-10 is a laminated core power transformer designed for through-hole mounting. It features dual primary windings rated for 115 VAC and 230 VAC, allowing parallel or series configuration. The secondary winding provides dual outputs of 5V AC, supporting parallel connection for 2A current or series connection for 1A current. With a power rating of 10 VA, the unit measures 47.6 mm in length, 39.7 mm in width, and 34.9 mm in height. It operates at 50/60 Hz frequencies.

Feature Summary

• Dual primary winding capability for flexible 115V or 230V input selection
• Dual secondary winding design enabling versatile voltage and current configurations
• Laminated core construction optimized for standard 50/60 Hz line frequencies

Applications

• General purpose AC power supply circuits
• Industrial control panel power distribution
• Consumer electronics internal power conversion

Procurement Notes

Verify that the specific suffix '10' corresponds to the 5V secondary rating before ordering. Confirm that the application requires through-hole termination style rather than surface mount alternatives. Ensure the operating environment remains within standard temperature limits specified for laminated transformers. Cross-reference pinout diagrams with PCB layout requirements to guarantee correct polarity for series or parallel secondary connections.

Selection Notes

Select this component when a 10 VA capacity is sufficient for the load requirements. Choose this model if the system requires isolation between primary mains and secondary low-voltage DC rectification stages. Consider the physical dimensions against available board space constraints. Evaluate the need for dual secondary outputs versus single higher-current options provided by other series variants.

Part Context

This part belongs to the 14A series of single-phase power transformers manufactured by Signal Transformer. The series offers various voltage configurations ranging from 5VA to 30VA ratings. These components are widely used in applications requiring reliable isolation and step-down functionality from standard utility voltages to lower AC levels for subsequent rectification.

Replacement Considerations

Hammond Manufacturing 183G12 serves as a similar alternative offering comparable 10 VA specifications.
