Overview
The Signal Transformer DST-2-10 is a laminated core power transformer designed for through-hole mounting. It features dual primary windings rated for 115V and 230V input, supporting parallel or series configurations. The secondary side provides dual outputs: a parallel configuration delivering 5V at 220mA maximum current, and a series configuration providing 10V at 110mA maximum current. With a total power rating of 1.1VA, this Class 2 transformer offers 2500Vrms isolation voltage. The unit measures 34.90mm in length, 28.60mm in width, and has a maximum installation height of 24.60mm.
Feature Summary
- Dual primary winding architecture enables flexible connection to both 115V and 230V AC mains supplies.
- Split bobbin construction facilitates independent secondary windings for versatile output configurations.
- Laminated core design ensures efficient magnetic coupling within a compact physical footprint.
- Class 2 compliance with high isolation voltage supports safe operation in low-power applications.
Applications
- Low-power electronic equipment requiring isolated DC power supplies
- Industrial control systems utilizing Class 2 power sources
- Consumer electronics with dual voltage input requirements
- Signal conditioning circuits needing galvanic isolation
Procurement Notes
Verify the specific datasheet version when sourcing, as manufacturing relocation notices may affect production details. Confirm that the component meets RoHS and REACH regulatory standards required for your target market. Ensure the through-hole pin spacing matches your PCB layout constraints before finalizing procurement orders.
Selection Notes
Select this model when a small form factor is critical alongside dual voltage input capability. The 1.1VA rating suits applications with minimal power consumption needs. Consider the physical dimensions carefully, as the height constraint may limit placement in densely populated assemblies compared to higher-power variants in the same series.
Part Context
This component belongs to the Split/Tran™ Class 2 Split Bobbin Transformers family, specifically the ST/DST series. These transformers utilize a split bobbin design to enhance safety and isolation characteristics. The manufacturer, Signal Transformer, produces this line to meet stringent international safety standards for low-voltage power conversion.
Replacement Considerations
Direct substitutes within the same series include models like DST-3-12 or DST-4-12 if higher power ratings are acceptable. Verify that any replacement maintains the same 115V/230V primary configuration and through-hole mounting style to ensure mechanical compatibility.
