ADH20048

Power Transformers Overview

The ADH20048 is a 1.1VA laminated power transformer manufactured by Zettler Magnetics, designed for through-hole mounting. It features a primary winding configuration supporting 115V and 230V inputs in parallel operation at 50/60Hz frequencies. The secondary side provides dual outputs: a parallel connection yielding 24V at 46mA, and a series connection providing 48V at 23mA. This component serves as a linear step-down solution for low-power AC applications requiring specific voltage isolation.

Power Transformers Feature Summary

• Provides isolated AC voltage transformation with dual secondary output configurations
• Supports flexible primary input options for global voltage compatibility
• Constructed with laminated core design for standard power frequency operation

Power Transformers Applications

• Low-power control circuitry requiring isolated AC supply
• Industrial equipment utilizing 24V or 48V auxiliary power rails
• General-purpose linear power supply stages

Power Transformers Procurement Notes

Verify the specific ordering suffix to confirm insulation class and regulatory approvals such as UL Class 2 or VDE certification. Ensure the selected variant matches the required thermal rating and physical footprint for the target PCB layout. Confirm that the through-hole pin spacing aligns with the assembly design before finalizing procurement orders.

Power Transformers Selection Notes

Select this transformer when a compact 1.1VA capacity is sufficient for the load requirements. Consider the ADH20048 if both 24V and 48V secondary options are needed from a single unit to simplify inventory. Evaluate the through-hole mounting style against available board space and mechanical stress constraints during the design phase.

Power Transformers Part Context

The ADH20048 belongs to the ADH series of linear power transformers from Zettler Magnetics. This series typically includes variants with different VA ratings and secondary voltages, such as the ADH20028 and ADH20036. These components are generally utilized in applications demanding reliable, low-noise AC power conversion within constrained physical envelopes.

Power Transformers Replacement Considerations

Cross-reference part numbers like ADH20028 or ADH20036 only if the application allows for different voltage or current ratings. Verify that any substitute maintains the same primary input specifications and through-hole package dimensions to ensure mechanical compatibility.
