DST-3-16

Overview

The DST-3-16 is a laminated core power transformer from the DST series, designed for through-hole mounting. It features dual primary windings rated for 115V and 230V AC input at 50/60Hz. The secondary configuration provides dual outputs of 8V and 16V with center taps, supporting maximum currents of 300mA and 150mA respectively. With a total power rating of 2.4VA, it offers 2500Vrms isolation voltage. The unit utilizes PC pin termination and measures 41.3mm in length, 33.3mm in width, and 33.3mm in height.

Feature Summary

• Dual primary winding design enables compatibility with both 115V and 230V AC line voltages.
• Split secondary architecture provides independent 8V and 16V outputs with center tap functionality.
• Laminated core construction ensures stable performance for servo and general power applications.

Applications

• Servo system power supplies
• Industrial control equipment requiring isolated DC rails
• General purpose AC to DC conversion circuits

Procurement Notes

Verify that the specific order matches the Signal Transformer manufacturer designation, as generic listings may refer to different variants. Confirm the package type is through-hole with PC pins, distinct from chassis mount or surface mount alternatives. Ensure the voltage ratings align with the target circuit requirements before finalizing procurement.

Selection Notes

Select this component when a compact, low-power transformer is needed for dual-voltage primary operation. The split secondary allows for flexible rectifier configurations to generate multiple DC voltage levels. Consider the physical dimensions and through-hole mounting style during PCB layout to ensure adequate clearance and mechanical stability.

Part Context

This part belongs to the DST series of signal transformers, which are characterized by their small footprint and high reliability. The series is commonly used in applications requiring galvanic isolation between primary and secondary circuits. The DST-3-16 specifically addresses needs for moderate power levels with versatile output tapping options.

Replacement Considerations

The Tamura 3FD-316 is listed as a direct substitute. Verify electrical parameters such as VA rating, voltage ratios, and current capacities against the original specifications to ensure functional equivalence in the target application.

FAQ

What is the isolation voltage rating?

The transformer provides an isolation voltage of 2500Vrms between the primary and secondary windings.

Can this transformer operate at frequencies other than 50/60Hz?

The datasheet specifies a frequency rating of 50/60Hz; operation outside this range is not confirmed by official documentation.
