14A-20-10

Overview

The Signal Transformer 14A-20-10 is a laminated core power transformer designed for board mount applications. It features dual primary windings rated for 115 VAC and 230 VAC input, providing versatile connectivity for global power standards. The unit delivers a 20 VA power rating with a single secondary output of 10 VAC. Electrical specifications include a maximum secondary current of 2 A. The component utilizes through-hole termination for secure PCB integration and offers 4000 Vrms isolation voltage between windings to ensure safety compliance in electronic circuits.

Feature Summary

• Dual primary winding configuration supports both 115 VAC and 230 VAC input voltages
• Provides 4000 Vrms electrical isolation between primary and secondary circuits
• Laminated core construction ensures efficient general-purpose power conversion
• Through-hole mounting style facilitates direct printed circuit board installation

Applications

• General power conversion in electronic equipment
• Industrial control systems requiring isolated power supplies
• Consumer electronics utilizing standard AC mains input

Procurement Notes

Verify the specific datasheet version for the 14A-20-10 model to confirm exact dimensional tolerances and terminal pin configurations before finalizing design integration. Ensure that the procurement documentation explicitly states RoHS compliance status as required by target market regulations. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current production status and availability constraints.

Selection Notes

Select this component when a 20 VA laminated transformer with dual primary inputs is required for board-mounted applications. The 10 VAC secondary output suits low-voltage rectification stages. Verify that the physical footprint accommodates the through-hole spacing and that the 4000 Vrms isolation meets the safety requirements of the end product enclosure design.

Part Context

This component belongs to the 14A series of laminated power transformers manufactured by Signal Transformer (BEL). The series is characterized by robust construction suitable for general industrial and commercial use. Similar models in the lineup vary primarily in power rating and secondary voltage configurations while maintaining consistent mounting styles and isolation characteristics.

Replacement Considerations

Direct substitutes may include other 20 VA laminated transformers with identical 115/230 VAC primary ratings and 10 VAC secondary outputs. Verify that any replacement maintains the same 4000 Vrms isolation rating and through-hole pinout dimensions to ensure mechanical and electrical compatibility without redesigning the PCB layout.
