14A-30-12

Overview

The Signal Transformer 14A-30-12 is a laminated core power transformer designed for board mount applications. It features dual primary windings rated for 115 VAC and 230 VAC operation at 50/60 Hz. The secondary configuration provides dual outputs of 6.3 VCT, supporting parallel connection for 4.8 A or series connection for 12.6 V at 2.4 A. With a 30 VA power rating and 4000 Vrms isolation voltage, it utilizes through-hole termination. Physical dimensions are approximately 41.3 mm in length, 36.5 mm in width, and 39.7 mm in height.

Feature Summary

• Dual primary winding capability allows flexible input voltage selection between 115 VAC and 230 VAC configurations.
• Configurable secondary output supports both parallel current mode (6.3 V at 4.8 A) and series voltage mode (12.6 V at 2.4 A).
• High isolation voltage rating of 4000 Vrms ensures safety compliance for general industrial and commercial equipment.

Applications

• Industrial control panels requiring isolated low-voltage AC power distribution
• Commercial machinery with mixed voltage input requirements
• General purpose power supplies utilizing rectifier circuits

Procurement Notes

Verify the specific datasheet revision to confirm terminal pinout and mounting hole specifications before integration. Ensure the application circuit matches the selected secondary configuration (parallel vs. series) to avoid incorrect voltage or current delivery. Confirm RoHS compliance status if required by regional regulations. Check for any recent product change notices that might affect physical dimensions or electrical characteristics.

Selection Notes

Select this component when a 30 VA capacity is sufficient for the load requirements. Choose this model over higher wattage variants if space constraints limit the use of larger chassis-mounted transformers. Consider the through-hole mounting style if PCB assembly processes do not support surface-mount technology. Verify that the 50/60 Hz frequency range aligns with the local power grid standards.

Part Context

This part belongs to the 14A series of laminated core power transformers from Signal Transformer. The series offers various power ratings and voltage configurations tailored for board-mount installations. It serves as a standard solution for converting mains voltage to lower AC levels for downstream electronic components.

Replacement Considerations

Direct replacements include other 30 VA laminated transformers with identical 115/230 VAC primary and 6.3 VCT secondary specifications. Verify mechanical footprint compatibility, specifically the 41.3 mm x 36.5 mm base and 39.7 mm height. Ensure the replacement unit maintains the 4000 Vrms isolation rating and through-hole termination type.
