ADH50028

Power Transformers Overview

The ADH50028 is a power transformer from the Zettler Magnetics ADH500 series, designed for through-hole mounting. It features a maximum power rating of 12VA and operates at 50/60Hz. The primary winding supports dual multi-tap configurations for 115V or 230V input voltages. Secondary outputs provide parallel connections of 14V or series connections of 28V, with corresponding maximum currents of 840mA in parallel mode and 420mA in series mode. The unit includes an isolation voltage of 4200V and measures 48.20mm in length by 40.20mm in width.

Power Transformers Feature Summary

• Dual multi-tap primary windings accommodate both 115V and 230V AC input sources.
• Flexible secondary output configuration allows for parallel 14V or series 28V operation.
• High isolation voltage capability ensures safety separation between circuits.

Power Transformers Applications

• General purpose AC to AC voltage conversion
• Industrial control panel power supplies
• Equipment requiring isolated power stages

Power Transformers Procurement Notes

Verify that the specific application requires the 12VA power rating and the exact secondary voltage configurations of 14V parallel or 28V series. Confirm that the physical dimensions of 48.20mm x 40.20mm fit within the designated enclosure space. Ensure the through-hole PC pin termination style matches the printed circuit board layout requirements before finalizing procurement.

Power Transformers Selection Notes

Select this component when a robust 12VA transformer is needed for standard 50/60Hz mains frequencies. The ADH50028 is suitable for designs requiring high isolation and flexible secondary voltage options. Consider the thermal performance and mechanical stability provided by the through-hole mounting style for applications subject to vibration or requiring secure physical attachment.

Power Transformers Part Context

This part belongs to the ADH500 series of open-frame power transformers manufactured by Zettler Magnetics. The series is characterized by through-hole construction and standardized footprints. The ADH50028 specifically represents the 12VA variant within this lineup, offering distinct electrical characteristics compared to lower or higher wattage models in the same family.

Power Transformers Replacement Considerations

Cross-reference with other 12VA transformers from Zettler Magnetics such as the ADH50036 if different secondary voltages are required. Verify that any substitute maintains the same 4200V isolation rating and through-hole mounting compatibility to ensure seamless integration into existing hardware designs.
