14A-30-10

Overview

The Signal Transformer 14A-30-10 is a laminated power transformer designed for board mount applications. It features dual primary windings rated for 115 VAC and 230 VAC input, providing flexibility across standard voltage regions. The unit delivers a secondary output of 30 VAC with a center tap, supporting a total power rating of 30 VA. Rated for operation at 50 Hz or 60 Hz frequencies, it utilizes through-hole mounting for secure PCB integration. The component includes a dielectric strength of 4000 Vrms to ensure electrical isolation safety.

Feature Summary

• Dual primary winding configuration supports both 115 VAC and 230 VAC input voltages
• Center-tapped secondary output provides flexible voltage options for rectifier circuits
• Laminated core construction ensures stable performance at 50/60 Hz operating frequencies
• Through-hole mounting style offers robust mechanical attachment on printed circuit boards

Applications

• Industrial control panel power supplies
• Rectifier power conversion circuits
• General purpose AC to DC power adapters
• Equipment requiring isolated low-voltage DC rails

Procurement Notes

Verify the specific manufacturing date code and RoHS compliance status upon receipt, as environmental certifications may vary by production batch. Confirm that the physical dimensions and pin spacing match the target PCB footprint before final assembly. Ensure the receiving facility has adequate storage conditions to prevent moisture absorption, which can affect insulation resistance in laminated transformers prior to soldering.

Selection Notes

Select this model when a compact board-mount solution is required for converting standard mains voltages to a regulated low-voltage DC rail. The 30 VA rating suits moderate current applications where space constraints preclude chassis-mounted units. Consider the thermal dissipation characteristics of the laminated core relative to the enclosure environment. Verify that the 115/230 VAC dual primary capability aligns with the regional power standards of the deployment location.

Part Context

This component belongs to the 14A series of laminated power transformers manufactured by Signal Transformer. The series is characterized by its board-mount form factor, making it suitable for direct integration into electronic assemblies. These transformers are engineered for reliability in industrial and commercial environments, offering consistent electrical performance across varying load conditions while maintaining strict isolation standards between primary and secondary windings.

Replacement Considerations

Direct substitutes include other 30 VA board-mount transformers with identical 115/230 VAC primary and 30V CT secondary ratings. Ensure replacement parts maintain the same through-hole pinout and physical envelope dimensions. Verify that alternative models meet the same 4000 Vrms dielectric strength requirement for safety compliance.
