VPT18-13800

Power Transformers Overview

The VPT18-13800 is a toroidal power transformer from Triad Magnetics rated at 250 VA. It features dual primary windings supporting 115V and 230VAC inputs, and dual secondary windings providing two independent 9V outputs. The unit utilizes an open center toroidal core design with wire lead terminations for chassis mounting. Electrical isolation is specified at 4000Vrms between windings. The component complies with UL and CE safety standards, ensuring suitability for industrial applications requiring robust voltage conversion and high isolation capabilities.

Power Transformers Feature Summary

• Dual primary and dual secondary winding configuration enables flexible input voltage selection and multiple output supply generation.
• High dielectric strength of 4000Vrms provides enhanced electrical isolation between primary and secondary circuits.
• Open center toroidal construction facilitates efficient thermal dissipation and compact mechanical integration.
• Compliance with UL and CE regulatory standards ensures adherence to international safety requirements.

Power Transformers Applications

• Industrial control systems requiring isolated power distribution
• Medical equipment power supplies demanding high isolation integrity
• Test and measurement instrumentation power conditioning
• Automated manufacturing machinery control circuits

Power Transformers Procurement Notes

Verify the specific datasheet version prior to ordering, as manufacturer specifications may undergo revisions. Confirm that the 250 VA rating aligns with the thermal management capabilities of the target enclosure. Ensure the 4000Vrms isolation specification meets the safety clearance requirements of the final assembly. Validate that the wire lead termination style is compatible with the intended connection method within the system architecture.

Power Transformers Selection Notes

Select this model when dual independent 9V outputs are required alongside universal AC input compatibility. The 250 VA capacity supports substantial load currents while maintaining stable voltage regulation. Consider the physical dimensions and open core geometry for adequate airflow in enclosed environments. Verify that the 4000Vrms isolation level exceeds the safety margins mandated by the application's regulatory framework.

Power Transformers Part Context

This component belongs to the World Series line of toroidal transformers manufactured by Triad Magnetics. The series is characterized by high-efficiency laminated cores and robust insulation systems designed for demanding industrial environments. The VPT18-13800 represents a mid-range power solution within this portfolio, balancing size constraints with significant power delivery capabilities for complex electronic systems.

Power Transformers Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Cross-referencing requires matching the 250 VA rating, dual 9V secondary configuration, and 4000Vrms isolation specification. Any alternative must support both 115V and 230V primary inputs with identical terminal types.
