Overview
The Vigortronix VTX-146-030-115 is an open-style toroidal power transformer designed for chassis mounting. It features a single primary winding rated at 230V AC and dual secondary windings providing 0-15V AC, allowing for parallel or series configurations. The unit has a power rating of 30VA with a maximum current capacity of 1A per secondary. Physical dimensions are approximately 31mm x 74mm, and it includes 150mm lead lengths for connection.
Feature Summary
- Open-style toroidal construction for compact integration
- Dual secondary windings supporting flexible voltage configuration
- Compliant with UL, CSA, TUV, EN60950, and EN60065 safety standards
Applications
- Audio equipment power supplies
- General electronic device power conversion
- Chassis-mounted industrial control systems
Procurement Notes
Verify the specific secondary voltage configuration (parallel vs. series) required for your circuit design before ordering. Confirm that the 30VA rating and 1A current limit meet the load requirements. Ensure the 230V primary input matches the local mains supply frequency and voltage. Check lead length specifications against PCB or terminal block spacing constraints to ensure proper fitment during assembly.
Selection Notes
Select this component when a compact, high-efficiency toroidal transformer is needed for low-power applications requiring split secondary voltages. Consider the physical envelope size of 31mm x 74mm for enclosure space planning. Evaluate the need for certified safety compliance in target markets. Compare against higher VA ratings if future expansion or increased thermal headroom is anticipated.
Part Context
This model belongs to the Vigortronix VTX series of open-style toroidal transformers. These components are engineered for efficient magnetic coupling and reduced electromagnetic interference compared to laminated core alternatives. The series offers various power ratings and winding configurations to suit diverse power supply architectures.
Replacement Considerations
Direct substitutes include other 30VA toroidal transformers with identical 230V primary and dual 15V secondary specifications. Verify dimensional compatibility and lead wire gauge equivalence. Ensure replacement units maintain the same safety certifications (UL/CSA/TUV) for regulatory compliance in the final assembly.
