Overview
The DST-7-10 is a Class 2 board-mount power transformer from the Split/Tran 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 unit provides a split secondary configuration with a 10 VCT winding capable of 3.6 A and a separate 5 V winding rated at 7.2 A. With a total power rating of 36 VA, it utilizes a laminated core design and through-hole solder pin termination for PCB integration.
Feature Summary
- Dual cavity platform construction
- Split secondary voltage outputs
- Through-hole mounting style
Applications
- General purpose AC to DC power supplies
- Industrial control equipment
- Consumer electronics power stages
Procurement Notes
Verify the specific datasheet revision and RoHS compliance status prior to procurement. Confirm that the dual primary winding configuration matches the target input voltage requirements of 115 VAC or 230 VAC. Ensure the PCB footprint accommodates the through-hole solder pin dimensions specified in the official mechanical drawings.
Selection Notes
Select this component when a single transformer must provide two distinct secondary voltages simultaneously. The 36 VA rating supports moderate current loads. Verify that the physical dimensions fit within the enclosure constraints and that the thermal performance meets the operating environment requirements without additional cooling.
Part Context
This model belongs to the DST series, which utilizes a dual cavity platform design. This architecture separates the primary and secondary windings to enhance isolation safety and reduce electromagnetic interference. The Split/Tran branding indicates the specific split-secondary output configuration available across this product line.
Replacement Considerations
Direct substitutes within the same series include models with identical electrical ratings but different secondary voltages, such as the DST-7-16 or DST-7-12. Cross-referencing mechanical dimensions is required when selecting alternative part numbers to ensure compatibility with existing PCB layouts.
