Overview
The DST-2-36 is a laminated power transformer from the Split/Tran Class 2 series by Signal Transformer. It features dual primary windings rated for 115 VAC and 230 VAC input, supporting 50 Hz and 60 Hz operation. The secondary configuration provides 36 VCT at 0.03 A or 18 V at 0.06 A, delivering a power rating of 1.1 VA. Designed for through-hole mounting with solder pins, it measures approximately 34.9 mm in length and 28.6 mm in width. The unit offers 2500 Vrms dielectric strength isolation.
Feature Summary
- Dual cavity split bobbin construction for enhanced safety compliance
- Rigid pin design ensures reliable board insertion and mechanical stability
- Class 2 certified for isolated power applications
Applications
- Servo system power supplies
- Industrial control circuit isolation
- Low-power electronic equipment requiring Class 2 isolation
Procurement Notes
Verify the specific secondary current requirement against the datasheet to ensure compatibility with load demands. Confirm that the 1.1 VA rating meets the application's thermal and electrical constraints. Check RoHS compliance status if required by regional regulations. Ensure the through-hole footprint matches the PCB layout dimensions provided in the official documentation.
Selection Notes
Select this component when a low-power, isolated transformer with rigid pin construction is required. The dual primary winding allows flexibility for different line voltages. Consider the physical dimensions and weight constraints for the enclosure design. Verify that the 2500 Vrms isolation voltage meets the safety standards of the target equipment.
Part Context
The DST-2-36 belongs to the Split/Tran DST series, which utilizes a dual cavity platform to provide robust isolation between windings. This series is designed for board-mount applications where space efficiency and reliability are critical. The laminated core construction supports standard frequency operations while maintaining compact physical profiles suitable for various industrial and commercial electronics.
Replacement Considerations
The ST-2-36 is a related part within the same product family. Verify if the surface mount or alternative package type of the ST variant is acceptable for the existing PCB design. Ensure that any substitute maintains the same electrical ratings and isolation specifications.
