VTX-121-3015-406

Power Transformers Overview

The Vigortronix VTX-121-3015-406 is a 1.5 VA encapsulated PCB mains transformer designed for direct board mounting. It features an EI30 core construction and accepts a primary voltage of 2 x 115 V. The unit provides two secondary outputs, each delivering 6 V. This component is engineered for reliable power conversion in compact electronic assemblies requiring isolated low-voltage DC or AC supplies derived from standard mains frequencies.

Power Transformers Feature Summary

• Encapsulated construction for environmental protection and mechanical stability
• Split Pack design optimized for printed circuit board integration
• Dual secondary windings providing independent 6 V outputs

Power Transformers Applications

• Control circuit power supplies
• Industrial equipment internal power distribution
• Consumer electronics mains interfacing

Power Transformers Procurement Notes

Verify the specific datasheet version to confirm insulation class and thermal ratings before integration. Ensure the PCB footprint matches the physical dimensions of the EI30 encapsulated package. Confirm that the dual 115 V primary configuration aligns with your input voltage scheme, as series or parallel connection options may vary by revision.

Power Transformers Selection Notes

Select this model when a small form factor and high isolation are required for low-power applications. The 1.5 VA rating suits control logic or relay driver circuits rather than high-current loads. Consider the encapsulation type if vibration resistance or moisture protection is critical for the deployment environment.

Power Transformers Part Context

This transformer belongs to the Vigortronix split-pack family, which specializes in through-hole mounted power transformers. These components are widely used in legacy and modern industrial systems where space constraints limit the use of larger open-frame units. The EI30 core size indicates a balance between efficiency and physical footprint.

Power Transformers Replacement Considerations

Cross-reference tools suggest parametrically similar parts for substitution. Verify that any alternative maintains the 1.5 VA rating, 2x115V primary, and 2x6V secondary specifications. Ensure the replacement part fits the existing PCB hole pattern and meets the same safety certification standards.
