DST-6-24

Overview

The Signal Transformer DST-6-24 is a laminated core power transformer from the Split/Tran Class 2 series, designed for through-hole mounting. It features dual primary windings rated for 115V and 230V inputs. The secondary configuration offers parallel operation at 12V with a maximum current of 400mA, or series operation at 24V with a maximum current of 200mA. The unit has a maximum power rating of 20VA and provides 2500Vrms isolation voltage. Physical dimensions are 57.20mm in length, 47.60mm in width, and 36.90mm in maximum height.

Feature Summary

• Split Bobbin construction supporting Class 2 safety standards
• Dual primary winding capability for global voltage compatibility
• Flexible secondary output options via parallel or series connection
• High isolation voltage rating for enhanced electrical safety

Applications

• Industrial control equipment requiring isolated power supplies
• Consumer electronics utilizing Class 2 low-voltage circuits
• General-purpose AC to DC power conversion stages
• Medical devices adhering to strict isolation requirements

Procurement Notes

Verify the specific secondary configuration required for your design, as the part supports both parallel and series outputs. Confirm that the through-hole PC pin termination matches your PCB layout. Ensure the 20VA power rating meets the load demands. Check for RoHS compliance status if environmental regulations apply to your manufacturing process. Validate physical clearance against the specified maximum height and footprint dimensions during assembly planning.

Selection Notes

Choose this component when a robust laminated core transformer is needed for Class 2 applications. It is suitable for designs requiring flexible secondary voltage options without multiple part numbers. Consider the physical size constraints, as it is larger than lower-power variants. Ensure the operating frequency aligns with standard 50Hz or 60Hz mains frequencies. Verify that the insulation class meets the safety standards of the target market.

Part Context

This transformer belongs to the DST series, which utilizes Split/Tran technology. This design separates primary and secondary windings on distinct bobbin sections to improve safety and reduce capacitive coupling. The series is characterized by high reliability and compliance with international safety standards for isolated power supplies.

Replacement Considerations

Direct substitutes may include other models within the Signal Transformer DST series with matching VA ratings and voltage configurations. Cross-reference physical dimensions and pinout arrangements carefully. Verify that any alternative maintains the same Class 2 safety certification and isolation voltage rating.
