ADH50020

Power Transformers Overview

The ADH50020 is a 12VA power transformer from the ADH500 series by Zettler Magnetics, designed for through-hole PCB mounting. It features a primary input of 115V or 230V AC at 50/60Hz. The secondary output provides parallel 10V at 1.2A or series 20V at 600mA. Key electrical specifications include a voltage isolation rating of 2500V and UL recognition for 50/60Hz operation. The component utilizes PC pin termination with dimensions of 48.20mm L x 40.20mm W and a maximum seated height of 35.90mm.

Power Transformers Feature Summary

Power Transformers Procurement Notes

Verify the specific suffix (e.g., -DG) against the manufacturer's current datasheet to confirm exact packaging and compliance certifications. Ensure the required secondary configuration (parallel vs. series) matches the circuit design before ordering. Confirm that the 2500V isolation rating meets the safety standards of the final application environment.

Power Transformers Selection Notes

Select this model when a 12VA capacity is sufficient for the load requirements. Consider the physical dimensions (48.20mm x 40.20mm) for board space constraints. Choose between parallel 10V or series 20V outputs based on the downstream rectification and regulation needs. Verify that the 50/60Hz frequency range aligns with the input power source.

Power Transformers Part Context

Part of the ADH500 series split bobbin power transformers. This series offers various voltage combinations while maintaining consistent mechanical footprints. The ADH50020 specifically addresses applications requiring moderate power density with standard through-hole assembly methods. It serves as a direct replacement for legacy transformers in existing 12VA designs.

Power Transformers Replacement Considerations

Check cross-reference lists for equivalent 12VA transformers with identical pinouts. Verify that substitute parts maintain the same 2500V isolation and 115/230V primary ratings. Ensure mechanical compatibility regarding the 35.90mm max height and PC pin spacing.
