VTX-146-080-118

Overview

The Vigortronix VTX-146-080-118 is an 80 VA toroidal power transformer designed for mains voltage applications. It features a single primary winding rated for 230V AC input and dual secondary windings providing 2 x 18V AC output. This configuration supports full-wave bridge rectifier circuits requiring split-phase DC supplies. The unit utilizes a toroidal core design to minimize electromagnetic interference and reduce physical footprint compared to laminated transformers.

Feature Summary

• Toroidal core construction for compact size and low magnetic leakage
• Dual secondary windings enabling split-phase power supply configurations
• Single primary winding optimized for standard 230V AC mains operation

Applications

• Audio amplifier power supplies
• Split-rail DC power distribution systems
• Electronic equipment requiring isolated dual voltage outputs

Procurement Notes

Verify the specific part number suffix against manufacturer documentation to confirm electrical ratings. Ensure the procurement channel provides original manufacturer packaging to prevent damage during transit. Confirm that the received unit matches the 80 VA rating and 2 x 18V specification before integration into final assemblies.

Selection Notes

Select this component when a compact, low-noise power source is required for circuits needing symmetrical dual voltages. The 80 VA rating determines the maximum continuous power capacity. Consider thermal management requirements based on the ambient operating conditions and enclosure ventilation capabilities of the target application.

Part Context

This model belongs to the VTX-146 series of toroidal transformers manufactured by Vigortronix. The series offers various power ratings and voltage configurations. The VTX-146-080-118 specifically denotes the 80 VA variant with dual 18V secondaries, distinguishing it from other models in the lineup with different wattage or voltage outputs.

Replacement Considerations

Direct substitutes must match the 80 VA power rating, 230V primary input, and 2 x 18V dual secondary output. Physical mounting dimensions and terminal pinout compatibility are critical for mechanical replacement. Verify insulation class and temperature rating equivalence.
