DST-6-48

Overview

The Signal Transformer DST-6-48 is a Class 2 board-mount power transformer designed for 50/60 Hz operation. It features dual primary windings rated for 115 VAC and 230 VAC input voltages. The secondary configuration provides a center-tapped output of 48 VCT with a corresponding 24 V rating, delivering a power capacity of 20 VA. The unit supports through-hole mounting and includes a dielectric strength of 2500 Vrms to ensure electrical isolation.

Feature Summary

• Dual primary winding design accommodates multiple international input voltage standards
• Center-tapped secondary architecture enables flexible bipolar or split-rail power distribution
• Through-hole construction facilitates secure integration into printed circuit boards

Applications

• Industrial control systems requiring isolated AC power conversion
• Servo drive circuits utilizing laminated transformer technology
• General-purpose equipment needing Class 2 safety isolation

Procurement Notes

Verify the specific datasheet version to confirm compliance with current regional safety regulations. Ensure that the PCB footprint matches the physical dimensions provided in the official documentation. Confirm that the operating environment temperature range aligns with the transformer's thermal ratings before finalizing procurement decisions.

Selection Notes

Select this component when a robust laminated core transformer is required for low-frequency applications. The dual primary capability simplifies global product deployment by supporting both 115V and 230V mains without variant changes. Consider the physical size constraints as through-hole mounting requires adequate board clearance for the lead frames.

Part Context

This model belongs to the DST series of power transformers manufactured by Bel Signal Transformer. The series is characterized by its use of laminated cores for standard frequency operations. It serves as a reliable solution for applications demanding high isolation and stable voltage transformation in industrial and commercial settings.

Replacement Considerations

Direct substitutes must match the 20 VA power rating, 48 VCT secondary output, and 115/230 VAC primary inputs. Verify that any alternative component maintains the same through-hole mounting style and meets equivalent dielectric strength requirements for safe replacement.
