Overview
The Signal Transformer DST-6-20 is a Class 2 board-mount power transformer featuring a laminated core and dual primary windings rated for 115 VAC and 230 VAC input. It provides dual secondary outputs of 10 VAC center-tapped to 5 VAC, delivering maximum currents of 2 A and 4 A respectively. The unit has a 20 VA power rating and supports through-hole mounting with PC pin termination. Physical dimensions are 57.2 mm in length, 47.8 mm in width, and 36.9 mm in height.
Feature Summary
- Dual primary winding configuration supporting both 115 VAC and 230 VAC operation
- Split bobbin design providing enhanced isolation between windings
- Class 2 safety classification for compliant low-energy applications
Applications
- General purpose AC/DC power supply circuits
- Industrial control panel power distribution
- Consumer electronics requiring isolated low-voltage DC rails
Procurement Notes
Verify the specific datasheet version for the DST-6-20 to confirm compliance with current RoHS directives and REACH regulations. Ensure that the ordering suffix matches the required lead frame or terminal configuration if applicable. Cross-reference the physical footprint against PCB layout constraints before finalizing procurement orders.
Selection Notes
Select this component when a 20 VA capacity is required with split secondary voltage options. The dual primary winding allows flexibility for global voltage standards without changing hardware. Consider the through-hole mounting style and specific dimensional envelope for mechanical integration within the target enclosure space.
Part Context
This model belongs to the Split/Tran™ series, which utilizes a split bobbin construction to maximize insulation integrity. The series is designed for board-mount applications where high isolation reliability is critical. The laminated core construction ensures efficient magnetic coupling while maintaining standard electrical performance metrics for general-purpose power transformation.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing circuit designs before attempting substitution with other manufacturers' transformers.
