Overview
The VTX-146-080-125 is an 80VA toroidal transformer featuring dual secondary windings rated at 2 x 25V. It provides a nominal secondary current of 1.66A per winding and utilizes wire lead terminals for connection. The unit is designed with an open center configuration to facilitate mounting hardware installation.
Feature Summary
- Toroidal core construction for efficient magnetic coupling
- Dual independent secondary voltage outputs
- Open center design for mechanical mounting flexibility
Applications
- Industrial power supply units requiring isolated AC sources
- Audio equipment amplifiers needing balanced or split rail voltages
- Control systems utilizing multiple low-voltage AC circuits
Procurement Notes
Verify the specific secondary voltage rating matches the target circuit requirements, as the 2x25V configuration is distinct from other variants in the series. Confirm that the wire lead termination type is compatible with the assembly process, as this component does not utilize PCB pins. Ensure the open center dimension allows for the intended bolt or stud mounting mechanism in the final enclosure design.
Selection Notes
Select this model when dual isolated AC outputs are required rather than a single rectified DC rail. The 80VA rating supports moderate load currents typical in professional audio or industrial control applications. Consider the physical dimensions and wire length if space constraints exist, as toroidal transformers have unique footprint requirements compared to E-I laminated types.
Part Context
This component belongs to the Vigortronix VTX series of toroidal transformers, which are characterized by high efficiency and low electromagnetic interference. The series offers various power ratings and voltage configurations to support diverse electronic design needs, ranging from consumer electronics to heavy industrial machinery.
Replacement Considerations
VTX-146-080-118 (2 x 18V), VTX-146-080-112 (2 x 12V), VTX-146-080-124 (2 x 24V). These substitutes share the same 80VA power rating and toroidal form factor but differ in secondary voltage output.
