DST-5-48

Overview

The DST-5-48 is a Class 2 power transformer from the Split/Tran series, designed for printed circuit board mounting via through-hole solder pins. It features dual primary windings rated for 115 VAC and 230 VAC inputs at 50 Hz or 60 Hz frequencies. The unit provides a dual secondary output of 48 VCT at 0.25 A and 24 V at 0.5 A, with a total power rating of 12 VA. Physical dimensions are approximately 48.4 mm in length, 40.4 mm in width, and 36.9 mm in height, weighing 320 grams.

Feature Summary

• Utilizes a dual cavity platform design for enhanced isolation and thermal performance.
• Supports universal input voltage compatibility through dual primary winding configuration.
• Offers flexible secondary output options with center-tapped and standard voltage taps.

Applications

• Servo power supply circuits
• Industrial automation control systems
• Class 2 low-voltage power distribution

Procurement Notes

Verify the specific datasheet version to confirm compliance with current safety standards and RoHS directives. Ensure that the procurement channel provides original manufacturer documentation to validate authenticity. Cross-reference the ordering suffix if variant availability is required. Confirm lead times as production cycles may vary based on regional manufacturing schedules.

Selection Notes

Select this component when a compact, through-hole mounted transformer is required for Class 2 applications. The dual primary winding allows operation across different global mains voltages without rewiring. Ensure the PCB layout accommodates the specified physical footprint and pin spacing. Verify that the load current does not exceed the rated secondary currents for either the center-tapped or full secondary configurations.

Part Context

This model belongs to the DST series of split-core transformers manufactured by Signal Transformer. These components are engineered for high reliability in industrial environments. The Split/Tran branding indicates a specific construction method aimed at improving magnetic coupling and reducing electromagnetic interference compared to standard wound transformers.

Replacement Considerations

The ST-6-48 offers similar electrical characteristics but utilizes a surface mount package instead of through-hole. Both parts share the same dual cavity platform technology. Verify mechanical fitment before substituting, as the mounting style differs significantly between the two models.
