Overview
The Vigortronix VTX-146-160-225 is a dual primary toroidal transformer with a 160VA rating. It accepts 115V or 230VAC input voltage and provides a dual output of 2 x 25VAC at 3.2A. The unit features an open style construction and is UL approved. Typical regulation is specified at 8%, with a temperature rise of 55°C.
Feature Summary
- Dual primary winding configuration for flexible input voltage selection
- Open style toroidal core design for efficient magnetic coupling
- UL approval indicating compliance with safety standards
Applications
- Audio coupling circuits
- Portable tool power supplies
- General electronic equipment power conversion
Procurement Notes
Verify the specific output voltage configuration matches the system requirements before procurement. Confirm that the open style housing fits within the intended enclosure dimensions. Ensure the 160VA rating aligns with the total load demand to prevent overheating. Check for UL certification marks on the physical unit to guarantee authenticity and safety compliance.
Selection Notes
Select this component when a dual secondary output is required from a single toroidal source. The dual primary feature allows compatibility with both 115V and 230VAC mains without rewinding. Consider the open style design if mounting hardware or external shielding is planned. The 160VA capacity supports moderate current loads typical in audio and industrial control applications.
Part Context
This model belongs to the Vigortronix VTX series of PCB mount toroidal transformers. These components are designed for integration into electronic devices where stable voltage transformation is critical. The series offers various VA ratings to suit different power requirements while maintaining consistent quality and safety approvals across the product line.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Cross-reference tools may identify parametrically similar parts, but direct substitution requires verification of electrical specifications and mechanical fit.
