VPL28-1700

Power Transformers Overview

The Triad Magnetics VPL28-1700 is a laminated core power transformer designed for chassis mounting. It features a maximum power rating of 50VA with dual primary windings supporting 115VAC or 230VAC input at 50/60Hz. The secondary configuration provides a center-tapped output of 28VCT at 1.7A, or parallel outputs of 14V at 3.57A. Key electrical specifications include a typical voltage regulation of 20% and a dielectric isolation capability of 3500VAC between primary and secondary windings.

Power Transformers Feature Summary

• Dual winding construction with insulated shrouds exceeding UL flammability requirements
• European style split bobbin design meeting International Safety Agency Standards
• Chassis mount installation with wire leads compatible with leaded processes

Power Transformers Applications

• Industrial power supply systems requiring international safety compliance
• Equipment needing 28VDC or 14VDC derived power rails
• General purpose AC to AC step-down applications in controlled environments

Power Transformers Procurement Notes

Verify the specific pinout configuration against the official datasheet before integration, as dual primary and secondary options exist. Confirm that the 3500VAC hipot rating meets your system's isolation requirements. Ensure the chassis mounting dimensions align with your enclosure design constraints. Check for RoHS compliance status if required by your manufacturing standards.

Power Transformers Selection Notes

Select this model when a 50VA capacity is required with flexible input voltage options. Consider the physical size constraints as it utilizes a laminated core rather than a toroidal design. Evaluate the leaded process compatibility if automated assembly is part of the production workflow. Compare against lower VA models like the VPL28-350 if power demands are reduced.

Power Transformers Part Context

This component belongs to the Triad Magnetics International Series, which emphasizes adherence to global safety agency standards. The series utilizes European-style split bobbins to ensure robust insulation and thermal performance. This specific model represents a mid-range power solution within the lineup, balancing output capacity with standard chassis mounting form factors.

Power Transformers Replacement Considerations

Direct substitutes may include other Triad Magnetics models within the same International Series offering similar VA ratings and voltage configurations. Verify mechanical footprint compatibility when considering alternative manufacturers. Ensure equivalent isolation voltages and regulatory certifications are maintained during substitution.
