DST-7-24

Overview

The DST-7-24 is a laminated core power transformer from the Signal Transformer DST series, designed for through-hole mounting. It features dual primary windings rated for 115V and 230V inputs and dual secondary windings providing 12V at 3A or 24VCT at 1.5A. The unit has a maximum power rating of 36VA and operates at 50/60 Hz. Key electrical specifications include a 2500Vrms isolation voltage and PC pin termination. Physical dimensions are 66.70mm in length, 55.50mm in width, with a maximum installation height of 40.40mm.

Feature Summary

• Utilizes a dual cavity platform design for enhanced structural integrity
• Supports split bobbin construction to facilitate Class 2 compliance
• Offers flexible secondary output configurations via parallel or series winding connections

Applications

• General purpose AC to DC power supply circuits
• Industrial control systems requiring isolated power stages
• Consumer electronics utilizing Class 2 safety standards

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status prior to ordering, as manufacturing relocation notices may affect production sources. Confirm that the required secondary current ratings align with the parallel or series connection options available for this part number. Ensure mechanical clearance accommodates the specified maximum height and footprint dimensions during PCB layout.

Selection Notes

Select this component when a 36VA capacity is required with dual primary voltage compatibility. The dual secondary winding architecture allows designers to choose between 12V high-current or 24VCT center-tapped outputs based on rectification needs. Consider the physical size constraints relative to lower-power variants in the DST series if space is limited.

Part Context

This transformer belongs to the Split/Tran™ Class 2 Split Bobbin Transformers family. The DST series shares common design characteristics with the ST series but includes dual primary windings for broader input voltage flexibility. These components are engineered for board mount applications using standard PC pin terminations.

Replacement Considerations

Publicly confirmed substitute part numbers are not explicitly listed in the provided documentation. Designers should consult the manufacturer's official cross-reference tools or datasheets for equivalent models within the same series or alternative manufacturers offering similar electrical and mechanical specifications.
