It features dual secondary windings providing 0-9V AC output, supporting a current of 1.67A per winding. The unit utilizes an open style construction designed for chassis mounting. This component is UL approved and complies with RoHS standards, ensuring low level radiated magnetic field emissions suitable for sensitive electronic applications.

Feature Summary

• Open style toroidal construction for efficient magnetic coupling
• Dual secondary windings enabling split voltage configurations
• Low level radiated magnetic field emission profile
• UL approval and RoHS compliance for safety and environmental standards

Applications

• Chassis mounted power supplies requiring split rail voltages
• Audio equipment power stages needing isolated secondary outputs
• Industrial control systems utilizing 230V AC input sources
• Electronic test instruments requiring low electromagnetic interference

Procurement Notes

Verify the specific secondary voltage configuration matches the design requirement of 0-9V AC dual windings. Confirm that the 30VA power rating aligns with the load demands of the target application. Ensure the chassis mounting dimensions are compatible with the enclosure layout. Check for UL certification marks on the physical unit to validate safety compliance. Review RoHS documentation if environmental restrictions apply to the manufacturing process.

Selection Notes

Select this model when a compact toroidal solution with dual independent secondary outputs is required. The 230V primary specification suits regions with standard mains voltage. Consider the open style design for custom potting or housing integration. Evaluate the 1.67A current capacity against peak load requirements. Compare alternative part numbers only if different secondary voltage ratios or higher power ratings are necessary for the system architecture.

Part Context

This component belongs to the Vigortronix VTX series of PCB and chassis mount transformers. The series offers various power ratings from 15VA to 1000VA. The VTX-146-030-109 specifically addresses needs for moderate power distribution with split secondary outputs. It represents a standard industrial grade transformer option for general purpose power conversion tasks.

Replacement Considerations

Cross-reference tools may identify parametrically similar parts. Verify that any substitute maintains the 30VA rating and 0-9V dual secondary configuration. Ensure the replacement supports 230V AC primary input. Check mechanical compatibility for chassis mounting. Confirm equivalent safety approvals such as UL certification before implementation.
