Overview
The Vigortronix VTX-146-050-155 is a toroidal power transformer with a 50VA rating. It features a single primary winding rated for 230V AC input. The secondary configuration provides dual outputs of 0-55V AC, supporting parallel operation at 55V or series operation at 110V. The unit includes an internal thermal fuse for protection and comes with a chassis mounting kit. Lead length is specified at 150mm. Compliance standards include UL, CSA, TUV, EN60950, and EN60065.
Feature Summary
- Toroidal core construction for efficient magnetic coupling
- Internal thermal fuse for overtemperature protection
- Chassis mount design with included hardware
- Dual secondary windings for flexible voltage configuration
Applications
- Audio equipment power supplies
- Industrial control systems
- Test and measurement instruments
Procurement Notes
Verify the specific regulatory compliance requirements for your target market before ordering. Confirm that the 230V primary voltage matches your local mains supply. Ensure the chassis mounting dimensions accommodate the M5 bolt size and 40mm bolt length specified in the documentation. Check if the 150mm lead length meets your wiring constraints.
Selection Notes
Select this model when a 50VA capacity is required with dual 55V secondary outputs. Consider the toroidal form factor for space efficiency and lower electromagnetic interference compared to EI cores. Verify that the 14% regulation meets your load stability needs. Ensure the open style fits within your enclosure ventilation requirements.
Part Context
This component belongs to the Vigortronix VTX series of toroidal transformers. These units are designed for general-purpose AC power conversion. The VTX-146-050-155 specifically addresses applications requiring isolated dual voltages from a standard mains input. It is part of a broader family offering various VA ratings and voltage combinations.
Replacement Considerations
Direct substitutes may include other 50VA toroidal transformers with identical 230V primary and 2x55V secondary specifications. Verify mechanical mounting hole patterns and overall dimensions to ensure fit. Cross-reference electrical parameters such as regulation and insulation class to maintain system performance.
