ADH30028

Power Transformers Overview

The ADH30028 is a 2.4VA power transformer manufactured by Zettler Magnetics, designed for through-hole mounting. It features a laminated core construction and supports dual primary voltage inputs of 115V and 230V. The secondary winding configuration offers parallel operation at 14V with 170mA current capacity, or series operation at 28V with 85mA current capacity. This component operates at standard frequencies of 50/60Hz and provides electrical isolation between the primary and secondary windings.

Power Transformers Feature Summary

• Dual primary voltage input capability for global compatibility
• Flexible secondary output options via parallel or series connection
• Through-hole mounting design for PCB integration
• Laminated core construction for efficient magnetic flux transfer

Power Transformers Applications

• Low-power AC to DC power supply units
• Industrial control system power modules
• Consumer electronics internal power distribution
• Signal isolation circuits requiring galvanic separation

Power Transformers Procurement Notes

Verify that the specific order matches the ADH30028 part number exactly, as Zettler Magnetics produces multiple variants within the ADH series with differing VA ratings and winding configurations. Confirm RoHS compliance status if required for your assembly process. Ensure the receiving inspection checks for physical integrity of the leads and absence of core damage prior to soldering.

Power Transformers Selection Notes

Select this transformer when a low power rating of 2.4VA is sufficient for the load requirements. Choose the parallel secondary configuration for higher current needs up to 170mA at 14V, or the series configuration for double voltage at reduced current up to 85mA. Ensure the PCB layout accommodates the through-hole footprint dimensions specified in the mechanical drawings.

Power Transformers Part Context

This component belongs to the ADH series of power transformers from Zettler Magnetics, which are characterized by their laminated core design and through-hole termination style. The series includes various models differentiated by power rating and secondary winding options, serving as fundamental components for isolated power conversion in electronic assemblies.

Power Transformers Replacement Considerations

Direct replacements must match the 2.4VA rating, 115/230V primary input, and compatible secondary voltage/current specifications. Verify that any substitute part maintains the same through-hole package dimensions and insulation class to ensure mechanical fit and safety compliance.
