VPP28-180-B

Power Transformers Overview

The VPP28-180-B is a board-mount power transformer from Triad Magnetics, rated at 5 VA. It features dual primary windings for 115V and 230V input configurations. The secondary output provides 28V center-tapped voltage with a maximum current of 180mA in series configuration, or 14V center-tapped at 360mA in parallel mode. Designed for through-hole installation, it utilizes solder pin termination. The unit measures 2.19 inches in length, 2.63 inches in width, and 1.56 inches in height, weighing approximately 521.6 grams.

Power Transformers Feature Summary

• Dual primary winding capability supports flexible 115V or 230V AC input selection.
• Configurable secondary output allows switching between series (28Vct) and parallel (14Vct) modes to match load requirements.
• Through-hole PCB mounting design ensures secure mechanical attachment via solder pins.

Power Transformers Applications

• Through-hole printed circuit board power supply circuits
• Industrial equipment drive trains requiring isolated AC power
• Hybrid vehicle electrical systems

Power Transformers Procurement Notes

Verify the specific suffix designation against manufacturer documentation to confirm if the -B variant differs electrically or mechanically from the standard VPP28-180 model. Ensure that the selected configuration aligns with the required primary voltage and secondary output topology for the target application before finalizing procurement orders.

Power Transformers Selection Notes

Select this component when a 5 VA laminated core transformer is needed for PCB integration. Consider the physical dimensions and weight constraints relative to the enclosure space. Evaluate whether the dual primary flexibility and configurable secondary outputs meet the specific voltage and current demands of the power stage design.

Power Transformers Part Context

This part belongs to the VPP series of world-series power transformers by Triad Magnetics. These components are designed for general-purpose AC to AC conversion in medium-power applications. The series offers standardized form factors to facilitate easy integration into various electronic assemblies without requiring custom magnetics engineering.

Power Transformers Replacement Considerations

The 183F28 is documented as a cross-reference part number for the VPP28-180 series. Verify compatibility regarding pinout, electrical ratings, and physical footprint before substituting.
