VTX-146-1000-255

Overview

The Vigortronix VTX-146-1000-255 is a toroidal power transformer featuring dual primary windings for 115V and 230V AC input selection. It provides a secondary output of 55V at full load, configurable in parallel or series connections. The unit is rated at 255VA capacity with a current rating of 2.55A. Designed for robust performance, it utilizes a toroidal core structure to minimize electromagnetic interference and physical footprint while maintaining high efficiency standards suitable for demanding electronic applications.

Feature Summary

• Dual primary winding configuration allows flexible voltage selection for global compatibility
• Toroidal core design ensures compact form factor and reduced magnetic leakage
• Secondary output supports both parallel and series connection modes for versatile voltage requirements

Applications

• Industrial control systems requiring isolated power sources
• Audio equipment power supplies needing low noise operation
• Test and measurement instrumentation power modules

Procurement Notes

Verify the specific secondary connection requirement (parallel vs. series) against the target application circuit before ordering. Confirm that the 255VA rating aligns with the peak load demands of the system. Ensure input voltage matches the selected primary winding configuration. Check for any specific mounting hardware requirements as toroidal transformers often require separate brackets or screws not included with the component.

Selection Notes

Select this model when a high-efficiency, low-noise power source is required for sensitive electronics. The dual primary feature makes it suitable for products intended for multiple regional markets without redesigning the power stage. Consider the physical dimensions and weight constraints, as toroidal transformers are denser than EI-core alternatives. Ensure adequate ventilation space is allocated around the unit to manage thermal dissipation during continuous operation.

Part Context

This component belongs to the Vigortronix VTX-146 series of toroidal transformers. This series is characterized by its use of high-quality silicon steel cores and copper windings to deliver stable power conversion. The VTX-146 line is widely recognized in the industry for reliability and consistent electrical performance across various industrial and commercial power supply designs.

Replacement Considerations

Direct replacements must match the 255VA rating, 55V secondary output, and dual primary input specifications. Verify that substitute models maintain the same physical envelope and mounting hole patterns to ensure compatibility with existing chassis designs. Cross-reference electrical parameters such as insulation class and temperature rise limits to guarantee equivalent safety and performance standards.
