VTX-146-030-112

Overview

The Vigortronix VTX-146-030-112 is a mains toroidal transformer with a power rating of 30 VA. It features a single primary winding rated for 230 V AC input. The secondary configuration provides dual outputs of 0-12 V AC, resulting in a center-tapped or dual low-voltage supply. The unit utilizes an open-style construction with 150 mm lead lengths for connection. It complies with UL, CSA, TUV, EN60950, and EN60065 safety standards.

Feature Summary

• Open-style toroidal core design for compact integration
• Dual 0-12 V AC secondary windings for flexible voltage requirements
• Compliance with major international safety certifications including UL, CSA, and TUV
• Minimal magnetic interference and vibration characteristics inherent to toroidal topology

Applications

• Audio equipment power supplies
• Industrial control systems
• Information Technology Equipment (ITE)
• Consumer electronics requiring isolated AC sources

Procurement Notes

Verify the specific suffix code '112' against the manufacturer's current datasheet to confirm the exact winding configuration and insulation class. Ensure that the 150 mm lead length meets the mechanical spacing requirements of the target enclosure. Confirm that the 30 VA rating provides sufficient headroom for peak load currents without exceeding thermal limits under continuous operation conditions.

Selection Notes

Select this component when a 30 VA capacity is required with a 230 V primary input. The dual 12 V secondary output is suitable for applications needing symmetrical rails or independent low-voltage circuits. Consider the open-frame form factor for custom mounting solutions where shielding is not strictly mandated by the system architecture.

Part Context

This model belongs to the Vigortronix VTX series of toroidal transformers. The series is characterized by high efficiency and compact size compared to laminated alternatives. The VTX-146-030-112 specifically denotes the 30 VA variant within the 146 physical dimension family, designed for general-purpose isolation and voltage transformation in electronic assemblies.

Replacement Considerations

Cross-reference tools may identify parametrically similar parts from other manufacturers. Verify that any substitute matches the 30 VA rating, 230 V primary, and dual 12 V secondary specifications exactly. Ensure physical dimensions and lead lengths are compatible with existing PCB or wiring harness layouts.
