VPT36-690

Power Transformers Overview

The Triad Magnetics VPT36-690 is a toroidal power transformer rated at 25VA. It features dual primary windings supporting 115VAC and 230VAC inputs at 50/60Hz, configurable in parallel or series. The secondary provides dual 18V outputs, allowing for parallel connection at 1.38A or series connection yielding 36VCT at 690mA. Designed for chassis mounting with wire leads, it meets UL and CE safety standards.

Power Transformers Feature Summary

• Toroidal core construction for efficient magnetic coupling
• Dual primary and secondary winding configurations for flexible voltage input and output
• Chassis mount design with wire lead termination

Power Transformers Applications

• Industrial control systems requiring isolated power
• Medical equipment power supplies
• Audio amplifier circuits

Power Transformers Procurement Notes

Verify the specific configuration requirements against the datasheet before ordering. Confirm that the chassis mounting hole dimensions align with your enclosure design. Ensure the input voltage matches the parallel or series wiring scheme specified in the electrical specifications to prevent damage.

Power Transformers Selection Notes

Select this component when a compact toroidal transformer is needed for 25VA applications. Choose based on the requirement for dual 18V secondaries to support either 36V series or 18V parallel loads. Consider the chassis mount style and wire lead termination for integration into existing panel designs.

Power Transformers Part Context

This part belongs to the Triad Magnetics VPT series of world-series toroidal transformers. These units are designed for industrial and medical grade applications, offering high efficiency and low noise compared to standard laminated transformers. The series supports a wide range of power ratings up to 2.5KVA.

Power Transformers Replacement Considerations

Direct substitutes may include other 25VA toroidal transformers with identical 115/230V primary and 18+18V secondary ratings. Verify mechanical footprint compatibility and insulation class requirements when cross-referencing alternative manufacturers.
