DST-7-36

Overview

The DST-7-36 is a board-mount power transformer from the Split/Tran series by Signal Transformer. It features dual primary windings rated for 115 VAC and 230 VAC operation at 50/60 Hz frequencies. The unit provides a dual secondary output of 36 VCT / 18 V with a power rating of 36 VA. Secondary current ratings are specified as 2.25 A per winding. The device utilizes through-hole mounting with solder pin termination. Key electrical specifications include a dielectric strength of 2500 Vrms. Physical dimensions are approximately 66.7 mm in length, 55.5 mm in width, and 40.4 mm in height.

Feature Summary

• Dual primary winding configuration supports versatile input voltage selection between 115 VAC and 230 VAC.
• Split secondary design delivers isolated center-tapped outputs suitable for full-wave rectification applications.
• Laminated core construction ensures stable performance across standard 50 Hz and 60 Hz line frequencies.

Applications

• Industrial control panel power supplies
• General purpose equipment requiring isolated DC power rails
• Class 2 compliant low-voltage power distribution systems

Procurement Notes

Verify that the specific order matches the exact part number DST-7-36 to ensure correct voltage and current ratings. Confirm that the receiving facility has appropriate handling procedures for laminated transformers. Check datasheet revisions for any updates regarding mechanical tolerances or insulation class changes before finalizing procurement documentation.

Selection Notes

Select this component when a 36 VA capacity is required with split secondary outputs. Ensure the application environment supports through-hole mounting constraints. Verify that the physical footprint fits within the designated PCB area. Confirm that the operating frequency aligns with the 50/60 Hz specification to maintain optimal efficiency and thermal performance.

Part Context

This transformer belongs to the DST series, designed for board-mounted applications. It shares the Split/Tran architectural approach found in related models like DST-7-16 and DST-6-10. The series emphasizes compact form factors while maintaining robust isolation capabilities. It serves as a standardized solution for converting mains voltage to lower AC voltages in industrial settings.

Replacement Considerations

Direct substitutes within the same series include DST-7-16 and DST-6-10, though these offer different secondary voltage ratings. Any replacement must match the 36 VA power rating and physical dimensions to ensure compatibility with existing mounting structures and thermal management designs.
