DST-2-48

Overview

The DST-2-48 is a laminated core power transformer from the Split/Tran Class 2 series by Signal Transformer. It features dual primary windings rated for 115 VAC and 230 VAC parallel operation. The secondary configuration provides 48 VCT or 24 V, with current ratings of 46 mA in parallel and 23 mA in series. With a 1.1 VA power rating, it utilizes through-hole mounting and quick connect terminals. Dimensions are approximately 34.9 mm length, 28.6 mm width, and 24.6 mm height.

Feature Summary

• Split bobbin construction providing enhanced isolation capabilities suitable for Class 2 applications
• Dual primary winding design allowing flexible input voltage selection between 115 VAC and 230 VAC
• Laminated core architecture ensuring stable performance at standard operating frequencies

Applications

• Industrial control panels requiring isolated low-voltage power supplies
• Medical equipment adhering to safety isolation standards
• Consumer electronics utilizing Class 2 power circuits

Procurement Notes

Verify that the specific application requires Class 2 isolation characteristics before procurement. Confirm that the 1.1 VA power rating meets the load requirements of the target circuit. Ensure the through-hole mounting style and terminal type are compatible with the PCB layout. Check regulatory compliance documentation for the intended market region.

Selection Notes

Select this component when high isolation is required within a compact form factor. The dual primary winding allows compatibility with global input voltages without rewiring. Consider the physical dimensions and through-hole mounting constraints during mechanical design. Evaluate if the 1.1 VA capacity suffices for the secondary load demands.

Part Context

This transformer belongs to the DST series, characterized by split bobbin technology for improved safety isolation. The series is designed for board-mount applications where space efficiency and regulatory compliance are critical. It serves as a fundamental power conversion component in systems requiring galvanic separation between primary and secondary circuits.

Replacement Considerations

Direct substitutes within the same series include DST-2-10 and DST-2-28, which share identical physical footprints and mounting styles but offer different secondary voltage outputs. Verify that any replacement maintains the required Class 2 isolation rating and power handling capacity.
