ADH20056

Power Transformers Overview

The ADH20056 is a 1.1VA open-frame power transformer manufactured by Zettler Magnetics, designed for through-hole mounting. It features dual primary windings supporting 115V or 230V input configurations at 50/60Hz. The secondary output provides parallel 28V or series 56V options with maximum currents of 40mA in parallel and 20mA in series. This component utilizes a split bobbin construction typical of the AH/ADH series.

Power Transformers Feature Summary

• Dual primary winding configuration allows flexible selection between 115V and 230V AC input sources.
• Split bobbin design supports multiple secondary voltage outputs including parallel 28V and series 56V configurations.
• Through-hole termination style facilitates standard PCB assembly processes.

Power Transformers Applications

• Low-power electronic equipment requiring isolated AC-DC conversion stages
• Industrial control systems utilizing 115V or 230V mains inputs
• Consumer appliances needing compact 1.1VA isolation transformers

Power Transformers Procurement Notes

Verify the specific datasheet version to confirm electrical tolerances and insulation ratings. Ensure the selected pin configuration matches the target PCB footprint. Confirm RoHS compliance status if environmental regulations apply to the final assembly. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Power Transformers Selection Notes

Select this model when a low-power 1.1VA isolation transformer is required for 50/60Hz applications. Choose based on the need for dual primary voltage compatibility and specific secondary output requirements of 28V parallel or 56V series. Consider the through-hole package constraints and physical dimensions during layout planning.

Power Transformers Part Context

The ADH20056 belongs to the AH/ADH series of split bobbin power transformers from Zettler Magnetics. These components are characterized by their laminated core construction and open-frame design. The series offers various power ratings and voltage combinations tailored for general-purpose power supply applications.

Power Transformers Replacement Considerations

Direct substitutes within the same series include ADH20016 and ADH200120, which share similar form factors but differ in power rating and secondary voltage specifications. Verify that alternative parts meet the same current and voltage requirements before substitution.
