DST-3-48

Overview

The Signal Transformer DST-3-48 is a laminated core power transformer rated at 2.4VA, designed for through-hole mounting. It features dual primary windings supporting 115V and 230V inputs in parallel configuration. The secondary output provides 24V at 100mA in parallel or 48V center-tapped at 50mA in series. Operating at 50/60Hz, this Class 2 transformer ensures robust galvanic isolation suitable for various electronic applications requiring reliable voltage conversion.

Feature Summary

• Dual cavity platform design providing enhanced structural integrity
• Galvanic isolation capability for safety-critical applications
• Through-hole termination style for secure PCB integration

Applications

• Power supply circuits requiring isolated DC conversion
• RF-related equipment needing signal isolation
• General industrial control systems with low power demands

Procurement Notes

Verify the specific datasheet version to confirm compliance with current RoHS standards and REACH regulations. Ensure that the ordering suffix matches the required pin configuration and insulation class. Cross-reference the manufacturer's part number with authorized distributor listings to confirm availability and lead times before finalizing procurement orders.

Selection Notes

Select this component when a compact, low-power transformer is needed for board-level assembly. The dual primary winding allows flexibility for different input voltages. Consider the physical dimensions and thermal characteristics relative to the enclosure space. Verify that the 2.4VA rating meets the load requirements of the downstream circuitry without exceeding temperature limits.

Part Context

This model belongs to the DST series from Signal Transformer, which utilizes a dual cavity platform. This series is engineered for general-purpose power transformation tasks. The laminated core construction contributes to efficient magnetic flux coupling while minimizing energy losses during operation.

Replacement Considerations

Direct substitutes include other models within the same series such as the DST-3-10 or DST-3-28, provided the voltage ratings match the application needs. Always verify electrical parameters and physical footprint compatibility before swapping components.
