VTX-121-3023-218

Power Transformers Overview

The Vigortronix VTX-121-3023-218 is a 2.3VA encapsulated power transformer designed for PCB mounting. It features a laminated core construction and accepts a primary voltage of 230V AC. The unit provides dual secondary outputs, each rated at 18V, which can be configured in parallel or series to deliver 18V or 36V respectively. The maximum output current is specified as 63mA. This component serves as an isolated power conversion element within electronic circuits.

Power Transformers Feature Summary

• Encapsulated construction for environmental protection
• Dual secondary windings allowing flexible voltage configuration
• Laminated core design for standard power transformation

Power Transformers Applications

• General purpose AC/DC power supply input stages
• Industrial control equipment isolation
• Information Technology Equipment (ITE) power systems

Power Transformers Procurement Notes

Verify the specific datasheet version for the VTX-121-3023-218 to confirm exact electrical tolerances and thermal characteristics. Ensure that the application circuit supports the 2.3VA rating and that the 230V primary input matches the local mains frequency and voltage standards. Confirm that the encapsulation type meets the required safety and insulation class for the target deployment environment.

Power Transformers Selection Notes

Select this component when a compact, encapsulated transformer with dual 18V secondaries is required for 230V AC input applications. The choice depends on the need for galvanic isolation and the specific current demand not exceeding 63mA. Consider the physical dimensions and PC pin termination style for compatibility with the printed circuit board layout constraints.

Power Transformers Part Context

This part belongs to the Vigortronix VTX series of PCB-mounted transformers. These components are typically used in low-power applications requiring reliable isolation between primary and secondary circuits. The series offers various VA ratings and voltage configurations to suit different industrial and commercial electronics designs.

Power Transformers Replacement Considerations

Direct substitutes may include other 2.3VA encapsulated transformers with identical 230V primary and dual 18V secondary specifications. Verify pinout compatibility and physical footprint before substitution. Alternative parts must maintain the same lamination type and insulation class to ensure equivalent performance.
