Overview
The Vigortronix VTX-146-160-212 is a toroidal power transformer with a 160VA rating. It features dual primary windings for 115V and 230V operation. The secondary output provides two isolated 12VAC lines, delivering a nominal current of 6.67A per winding. Designed for chassis mounting, the unit incorporates thermal fuses for internal protection against overheating.
Feature Summary
- Dual primary winding configuration supports both 115V and 230V input voltages
- Dual secondary outputs provide independent 12VAC channels
- Integrated thermal fuses ensure protection against excessive temperature
Applications
- Audio amplifier power supplies
- Industrial control systems requiring isolated voltage rails
- Chassis-mounted electronic equipment
Procurement Notes
Verify that the specific application requires dual 12VAC outputs rather than a single center-tapped configuration. Confirm that the chassis mounting holes align with the physical dimensions specified in the official datasheet. Ensure the thermal fuse ratings are compatible with the enclosure's ventilation requirements to prevent nuisance tripping during normal operation.
Selection Notes
Select this component when a 160VA capacity is required with separate 12VAC circuits. The dual primary design allows flexibility for global voltage standards without manual rewiring. Consider the chassis mount style if panel installation is preferred over PCB integration. Verify that the 6.67A current rating meets the peak load demands of the connected circuitry.
Part Context
This model belongs to the Vigortronix VTX-146 series of toroidal transformers. The series is characterized by high efficiency and low magnetic interference compared to laminated core alternatives. The VTX-146-160-212 specifically addresses applications needing robust power conversion with built-in safety mechanisms via thermal fusing.
Replacement Considerations
Cross-reference tools may identify parametrically similar parts. Ensure any substitute matches the 160VA rating, dual 12VAC output specification, and chassis mounting footprint. Verify that the replacement also includes thermal protection features.
