DST-4-48

Overview

The Signal Transformer DST-4-48 is a laminated core power transformer designed for board mount applications. It operates at 50/60 Hz with a 6 VA power rating. The primary winding supports 115 VAC and 230 VAC inputs, configured in parallel. The secondary output provides dual windings rated at 48 VCT (0.125 A) and 24 V (0.25 A), also configured in parallel. The component utilizes through-hole termination and features a Class 2 isolation rating.

Feature Summary

• Dual cavity platform design for versatile mounting
• Class 2 safety isolation rating
• Laminated core construction for standard frequency operation

Applications

• Industrial control panels
• General purpose power supplies
• Equipment requiring isolated low voltage DC conversion

Procurement Notes

Verify the specific datasheet version to confirm terminal configuration and insulation class. Ensure the application circuit matches the 6 VA power limit and current ratings. Confirm that the through-hole footprint aligns with the PCB layout requirements before finalizing procurement orders.

Selection Notes

Select this model when a compact, board-mount solution is required for 50/60 Hz applications. It is suitable for systems needing simultaneous 24 V and 48 V outputs from a single unit. Consider the physical dimensions and lead spacing to ensure compatibility with the target assembly process.

Part Context

This component belongs to the DST series of power transformers from Signal Transformer. The series offers various voltage configurations within a standardized dual-cavity package. This specific part number represents a common industrial variant providing dual secondary voltages.

Replacement Considerations

Direct substitutes must match the 6 VA rating, 115/230 VAC primary, and 48 VCT/24 V secondary specifications. Verify pinout compatibility and physical envelope dimensions to ensure interchangeability without redesigning the host PCB.
