VTX-146-160-118

Overview

The Vigortronix VTX-146-160-118 is a high-quality open-style toroidal transformer with a 160 VA power rating. It features a single primary winding rated for 230V AC input. The secondary configuration provides dual outputs of 0-18V AC, resulting in a center-tapped 36V AC arrangement. This component is designed for robust performance in applications requiring reliable voltage transformation and isolation.

Feature Summary

• Open-style toroidal core construction for efficient magnetic coupling
• High dielectric strength insulation rated at 4200 Vrms
• Includes mounting hardware kit with rubber pads, nuts, bolts, and washers

Applications

• Audio amplifier power supplies
• Industrial control systems
• General-purpose AC power distribution

Procurement Notes

Verify the specific voltage configuration (2x 18V) against schematic requirements to ensure compatibility with downstream rectification circuits. Confirm that the 160 VA rating meets peak load demands including inrush currents. Check for compliance certifications relevant to the target market. Ensure physical dimensions allow for adequate airflow and clearance within the enclosure design.

Selection Notes

Select this model when a 160 VA capacity is required with a 230V primary input. The dual 18V secondary output suits bridge or center-tapped rectifier topologies. Consider the open-frame design for custom mounting solutions using the provided hardware. Evaluate thermal management needs based on ambient operating conditions and load duty cycles.
