VTX-146-250-240

Overview

The Vigortronix VTX-146-250-240 is a toroidal power transformer designed for chassis mounting. It features a primary voltage rating of 115V and 230V AC. The secondary winding provides dual outputs configurable for parallel or series connection, delivering 40V at full load in parallel mode and 80V in series mode. The maximum output current is rated at 3.125A. This component serves as a critical isolation and voltage transformation element in industrial electronic systems requiring robust magnetic coupling.

Feature Summary

• Toroidal core construction for efficient magnetic flux containment
• Dual secondary winding configuration supporting flexible voltage scaling
• Chassis mount design for secure mechanical integration

Applications

• Industrial control systems
• Power supply input stages
• Equipment requiring isolated AC voltage transformation

Procurement Notes

Verify the specific application voltage requirements against the primary ratings of 115V and 230V. Confirm that the mechanical layout accommodates the physical dimensions required for chassis mounting. Ensure the load current does not exceed the 3.125A maximum rating to maintain operational integrity and thermal safety margins during continuous use.

Selection Notes

Select this model when a toroidal topology is preferred for its compactness and low electromagnetic interference characteristics. The dual secondary option allows designers to choose between 40V or 80V outputs based on downstream circuit needs. Ensure the mounting hardware supports the weight and vibration profile typical of toroidal transformers in fixed installations.

Part Context

This part belongs to the Vigortronix VTX-146 series, which focuses on high-power toroidal transformers. The series is characterized by robust construction suitable for demanding environments. The VTX-146-250-240 variant specifically addresses applications needing mid-range power levels with flexible secondary voltage options.

Replacement Considerations

Direct substitutes must match the 250VA power rating, toroidal form factor, and identical primary/secondary voltage configurations. Verify that any alternative component meets the same chassis mounting specifications and current capacity of 3.125A to ensure system compatibility.
