VTX-146-225-215

Overview

The Vigortronix VTX-146-225-215 is a 225 VA toroidal power transformer designed for open-style mounting. It features dual primary windings supporting 115V and 230V AC input frequencies. The secondary configuration provides two isolated 15V outputs, delivering a total of 2x15V at full load capacity. This component utilizes a toroidal core geometry to minimize electromagnetic interference and physical footprint while maintaining high efficiency standards suitable for demanding electronic applications.

Feature Summary

• Toroidal core construction for reduced magnetic leakage and compact form factor
• Dual primary winding capability for flexible 115V or 230V AC input selection
• Dual secondary output configuration providing isolated 2x15V voltage rails
• Open-style design intended for chassis or panel integration

Applications

• Industrial control systems requiring stable dual voltage supplies
• Audio equipment power stages needing low-noise toroidal transformers
• Test and measurement instrumentation power modules
• Medical device internal power distribution units

Procurement Notes

Verify the specific datasheet version against the manufacturer's official documentation before procurement. Confirm that the dual primary winding configuration matches the available line voltage in the target deployment region. Ensure mechanical clearance specifications align with the intended chassis mounting layout. Cross-reference the secondary current ratings with the actual load requirements to prevent thermal overload during continuous operation.

Selection Notes

Select this model when a 225 VA capacity is required with precise 2x15V secondary outputs. The toroidal shape is preferred where space constraints and electromagnetic compatibility are critical. Consider the open-style mounting requirement as it lacks an integrated enclosure. Evaluate the thermal dissipation characteristics of the installation environment to ensure adequate cooling for continuous duty cycles under full load conditions.

Part Context

This component belongs to the Vigortronix VTX-146 series of toroidal power transformers. The series is characterized by high-efficiency wound cores and robust insulation systems. The VTX-146-225-215 specifically denotes the 225 VA power rating and the unique secondary voltage configuration. It serves as a fundamental power conversion element within larger electrical assemblies.

Replacement Considerations

Direct substitutes must match the 225 VA rating, 2x15V secondary output, and toroidal form factor. Verify pinout compatibility and mounting hole patterns if replacing in existing hardware. Alternative models from other manufacturers require careful validation of insulation class and temperature rise characteristics.
