ADH20016

Power Transformers Overview

The ADH20016 is a laminated core power transformer from the Zettler Magnetics ADH200 series, rated at 1.1VA for 50/60Hz operation. It features a horizontal split bobbin construction with PC pin through-hole termination. The primary winding supports 115V or 230V input configurations. Secondary outputs include parallel 8V and series 16V windings, providing 140mA and 70mA current ratings respectively. The unit offers 2500Vrms isolation voltage across eight terminals.

Power Transformers Feature Summary

• Horizontal split bobbin design for PCB mounting
• Laminated core construction for efficient power transfer
• Dual secondary voltage options via parallel and series connections

Power Transformers Applications

• Low-power AC to DC conversion circuits
• Control panel power supplies
• Industrial instrumentation power stages

Power Transformers Procurement Notes

Verify the specific secondary configuration required (parallel vs. series) against the application schematic before ordering. Confirm that the 1.1VA rating meets the load requirements. Ensure the through-hole footprint matches the target PCB layout. Check for any specific insulation class certifications required by the end-use equipment standards.

Power Transformers Selection Notes

Select this component when a compact, low-voltage power source is needed for control circuits. The split bobbin design facilitates easy assembly on printed circuit boards. Consider the 1.1VA limit for total system power consumption. Evaluate the 2500Vrms isolation if safety separation between primary and secondary sides is critical for the design.

Power Transformers Part Context

This part belongs to the ADH200 series of open-frame power transformers manufactured by Zettler Magnetics. The series provides various VA ratings and secondary configurations while maintaining a consistent form factor. These transformers are designed for general-purpose power supply applications requiring reliable isolation and standard through-hole mounting.

Power Transformers Replacement Considerations

Cross-reference with other ADH200 series variants such as ADH20010 or ADH20020 if different VA ratings or secondary voltages are acceptable. Verify that any substitute maintains the same 115V/230V primary compatibility and through-hole pinout dimensions.
