VPP20-1500-B

Power Transformers Overview

The Triad Magnetics VPP20-1500-B is a laminated core power transformer designed for board mount applications. It features dual primary windings supporting 115VAC and 230VAC inputs at 50/60Hz, selectable via parallel or series connection. The secondary output provides 20VCT at 1.5A in series configuration or 10V at 3A in parallel. Rated at 30VA with an isolation voltage of 4kV, it utilizes through-hole solder pin termination.

Power Transformers Feature Summary

• Dual bobbin construction reduces capacitance and eliminates the need for electrostatic shielding
• Flexible winding configuration allows selection between series or parallel input/output connections
• High insulation resistance and robust hipot testing ensure safety compliance

Power Transformers Applications

• Industrial control systems requiring isolated AC power
• Audio equipment power supplies
• General purpose electronic circuit prototyping

Power Transformers Procurement Notes

Verify the specific suffix requirements for your application, as the -B designation may indicate distinct packaging or handling specifications compared to the standard VPP20-1500 variant. Confirm that the physical dimensions and pin spacing match your PCB layout constraints prior to ordering. Ensure input voltage configuration aligns with the available wiring options for the dual primary windings.

Power Transformers Selection Notes

Select this component when a compact, high-isolation transformer is required for low-power AC applications. The dual primary design offers versatility for global voltage compatibility. Consider the thermal rise characteristics and mounting orientation to ensure adequate heat dissipation within the final enclosure design.

Power Transformers Part Context

This unit belongs to the World Series line of transformers from Triad Magnetics. These components are engineered for reliability in demanding environments, featuring insulated shrouds made from high-temperature materials that exceed UL flammability standards. The series emphasizes safety and durability for continuous operation.

Power Transformers Replacement Considerations

The standard VPP20-1500 serves as a direct functional equivalent. Verify if the -B suffix denotes specific packaging differences rather than electrical changes. Cross-reference mechanical footprints to ensure compatibility with existing assembly processes.
