Power Transformers datasheet and documents for VTX-120-3803-215
Power Transformers Overview
The VTX-120-3803-215 is a PCB mount transformer manufactured by Vigortronix. It features a single primary winding rated for 230V AC input and a twin secondary winding configuration providing two isolated 15V AC outputs. The unit has a power rating of 3VA. Designed for through-hole mounting on printed circuit boards, this component provides electrical isolation between the primary supply and the secondary loads.
Power Transformers Feature Summary
- Single primary winding with dual isolated secondary windings
- Vacuum epoxy encapsulated construction for durability
- Designed for direct PCB mounting
Power Transformers Applications
- Electronic equipment designs requiring isolated low-voltage AC supplies
- Power stages in information technology equipment
- General purpose signal or power isolation circuits
Power Transformers Procurement Notes
Verify the specific part number against official Vigortronix documentation to confirm the 230V primary and 15V+15V secondary configuration. Ensure the required 3VA power rating meets the application's load demands. Confirm that the PCB footprint matches the physical dimensions specified in the manufacturer's datasheet before ordering.
Power Transformers Selection Notes
Select this component when a 230V AC input must be stepped down to dual 15V AC outputs with galvanic isolation. The 3VA rating limits the maximum current per secondary winding. Verify that the vacuum epoxy encapsulation meets the environmental requirements of the target installation. Ensure the PCB layout accommodates the through-hole pin spacing.
Power Transformers Part Context
This transformer belongs to the Vigortronix VTX series of PCB-mounted transformers. These components are engineered for reliability in compact electronic assemblies. The series offers various voltage configurations and power ratings to suit different isolation needs within standard industrial and commercial electronics designs.
