VTX-146-625-245

Overview

The Vigortronix VTX-146-625-245 is a 625 VA toroidal power transformer designed for chassis mounting. It features dual primary and dual secondary windings with wire lead terminations. The unit provides two 45V secondary outputs, resulting in a nominal secondary current of 6.95A per winding. The core dimensions are 144.00mm in diameter and 72.00mm in maximum seated height. This open-style component complies with RoHS standards and is engineered to minimize acoustic vibration and hum while delivering high efficiency.

Feature Summary

• Toroidal core construction ensures high efficiency and compact physical footprint
• Dual primary and dual secondary winding configuration allows flexible voltage input and output options
• Open style design with wire leads facilitates direct integration into custom equipment assemblies

Applications

• High-power audio amplifier systems requiring low noise operation
• Industrial control panels needing stable voltage conversion
• Test and measurement equipment chassis installations

Procurement Notes

Verify that the receiving facility has adequate space for the 144mm diameter and 72mm height constraints. Confirm that the wiring harness supports the required 6.95A current load on each secondary leg. Ensure the installation environment accommodates the thermal characteristics of an open-style transformer without enclosed housing restrictions.

Selection Notes

Select this model when a 625 VA capacity is strictly required alongside specific 2x45V output requirements. The dual-winding architecture suits applications needing isolated or configurable secondary voltages. Consider the chassis mount form factor if panel integration is preferred over PCB mounting alternatives.

Part Context

This component belongs to the Vigortronix VTX series of toroidal transformers. The series emphasizes robust performance for demanding electronic designs. The VTX-146-625-245 specifically addresses the need for higher power handling within a standardized dimensional envelope common to the 146mm diameter family.

Replacement Considerations

Cross-reference part numbers such as VTX-146-500-230 for lower capacity needs. Verify that any substitute maintains the 144mm diameter and 72mm height limits to ensure mechanical compatibility with existing chassis cutouts and mounting hardware.
