VTX-146-225-155

Overview

The Vigortronix VTX-146-225-155 is a toroidal power transformer with a 225 VA rating. It features a single primary winding rated for 230V AC input. The unit includes dual secondary windings, each providing 55V, allowing for parallel operation at 55V or series operation at 110V. Designed for chassis mounting, it measures 110mm in outer diameter and 50mm in height.

Feature Summary

• Toroidal core construction for efficient magnetic coupling
• Dual secondary windings enabling flexible voltage configuration
• Chassis mount design for secure mechanical installation

Applications

• Industrial control systems requiring isolated power
• Audio equipment power supplies
• Medical device instrumentation

Procurement Notes

Verify the specific datasheet version to confirm insulation class and temperature rise limits. Ensure the mounting hole pattern matches the chassis design. Confirm that the 230V primary rating aligns with the local mains supply frequency and voltage stability requirements before finalizing the order.

Selection Notes

Select this model when a 225 VA capacity is required with dual 55V outputs. Consider the physical dimensions of 110mm diameter and 50mm height against available chassis space. Evaluate whether the fixed 230V primary input suits the operational environment without additional step-up transformers.

Part Context

This component belongs to the Vigortronix VTX series of toroidal transformers. These units are characterized by low noise and high efficiency compared to laminated cores. The VTX-146-225-155 specifically addresses applications needing robust isolation and flexible secondary voltage options from a standard single-phase input.

Replacement Considerations

Cross-reference with other 225 VA toroidal transformers featuring dual 55V secondaries. Verify dimensional compatibility and electrical ratings before substituting.
