DST-3-24

Overview

The DST-3-24 is a laminated core power transformer from the Split/Tran series, designed for through-hole mounting. It features dual primary windings rated for 115V and 230V operation in parallel configuration. The secondary side provides dual outputs of 12V at 200mA (parallel) or 24V at 100mA (series). With a maximum power rating of 2.4VA, it offers 2500Vrms isolation voltage. The unit measures 34.90mm in length, 28.60mm in width, and has a maximum installation height of 30.80mm.

Feature Summary

• Split bobbin construction for enhanced safety isolation
• Dual primary winding capability for universal input voltage compatibility
• Dual secondary winding design supporting flexible output configurations

Applications

• Industrial control systems requiring isolated power supplies
• Consumer electronics with dual voltage input requirements
• General purpose AC to DC power conversion circuits

Procurement Notes

Verify the specific datasheet version when ordering, as manufacturing relocation notices may affect production details. Confirm that the required pinout matches the standard through-hole configuration. Ensure the application environment does not exceed the thermal limits associated with the 2.4VA rating. Check for any regional compliance certifications relevant to the deployment location.

Selection Notes

Select this component when a compact, low-power transformer with split bobbin isolation is required. It is suitable for designs needing both 12V and 24V options from a single magnetic component. Consider the physical dimensions against available PCB space. Verify that the 2500Vrms isolation meets the safety standards of the target equipment.

Part Context

This part belongs to the Signal Transformer DST series, which utilizes split bobbin technology to improve creepage and clearance distances. The series is characterized by laminated cores and through-hole termination styles, offering a balance between performance and cost-effectiveness for general-purpose applications.

Replacement Considerations

Direct substitutes include the ST-3-24 from the same manufacturer family. Other potential replacements found in market data include models from Pulse Electronics and Tamura, though electrical parameters must be cross-referenced carefully.
