ADH40016

Power Transformers Overview

The ADH40016 is a through-hole power transformer manufactured by Zettler Magnetics with a maximum power rating of 6VA. It features an open-frame design suitable for PCB mounting via PC pins. The primary winding supports 115V and 230V inputs at 50/60Hz, configured in parallel or series respectively. The secondary output provides dual voltages: 8V at 800mA in parallel configuration and 16V at 400mA in series configuration. The unit offers an isolation voltage of 2500Vrms and complies with RoHS standards.

Power Transformers Feature Summary

Power Transformers Procurement Notes

Verify the specific datasheet revision to confirm insulation class and thermal characteristics required for your enclosure. Ensure the mounting hole pitch matches your PCB layout before ordering. Confirm that the 6VA rating meets the peak load requirements of your downstream circuitry without exceeding thermal limits under continuous operation conditions.

Power Transformers Selection Notes

Choose this component when a compact, low-cost solution is needed for standard line voltages. The dual secondary winding capability allows designers to select between higher current at lower voltage or lower current at higher voltage based on load needs. Consider the physical dimensions and lead spacing to ensure compatibility with automated assembly processes if high volume production is planned.

Power Transformers Part Context

This part belongs to the ADH400 series of open-frame power transformers from Zettler Magnetics. The series typically includes variants with different power ratings and secondary tap configurations. These transformers are designed for general industrial and commercial applications where space constraints and cost efficiency are prioritized over high-frequency switching performance.

Power Transformers Replacement Considerations

Cross-reference models such as the ADH40020 may offer similar form factors but differ in power rating or secondary voltage taps. Verify pinout compatibility and electrical parameters before substitution. No direct equivalent substitutes are explicitly confirmed in public documentation.
