DST-6-12

Overview

The DST-6-12 is a laminated core power transformer from the Split/Tran Class 2 series, designed for through-hole mounting on printed circuit boards. It features dual primary windings rated for 115 VAC and 230 VAC operation at 50 Hz or 60 Hz frequencies. The secondary configuration provides parallel outputs of 6.3 V at 3.2 A and series outputs of 12.6 V at 1.6 A, delivering a total power rating of 20 VA. The unit measures 57.2 mm in length, 47.6 mm in width, and 36.9 mm in height, with a dielectric strength of 2500 Vrms.

Feature Summary

• Dual primary winding design allows flexible voltage selection between 115 VAC and 230 VAC inputs.
• Split bobbin construction supports versatile secondary configurations for parallel or series output connections.
• Class 2 safety isolation rating ensures compliance with standard low-energy circuit requirements.

Applications

• Regulated DC power supply circuits requiring 5 VDC or ±12 VDC/±15 VDC outputs
• Industrial control systems utilizing split bobbin transformers
• Servo power applications needing isolated AC-to-AC conversion

Procurement Notes

Verify that the specific order matches the DST-6-12 part number to ensure correct 20 VA rating and pinout compatibility. Confirm that the receiving facility accepts laminated core transformers for through-hole assembly processes. Check RoHS compliance documentation if environmental regulations apply to the final product assembly line.

Selection Notes

Select this component when a 20 VA capacity is required for board-mounted applications. Ensure the PCB layout accommodates the specified physical dimensions of 57.2 mm by 47.6 mm. Verify that the system operates within the 50 Hz to 60 Hz frequency range and requires Class 2 isolation standards for safety certification.

Part Context

This model belongs to the DST series of Split/Tran transformers manufactured by Signal Transformer. These units are characterized by their laminated core construction and split bobbin architecture, which facilitates efficient thermal management and electrical isolation. The series is widely used in general-purpose power conversion tasks where reliable board-level mounting is necessary.

Replacement Considerations

The DMT-6-12 offers similar 6 VA ratings but utilizes chassis mounting rather than through-hole PCB installation. The DP-241-6-120 provides higher 30 VA capacity but differs significantly in secondary voltage specifications and industrial form factor. Direct substitution requires verifying mechanical fit and electrical parameter alignment.
