Procurement Notes

Verify the specific datasheet version and RoHS compliance status prior to ordering, as manufacturing specifications may evolve. Confirm that the chassis mounting style and terminal type align with your enclosure design. Ensure the 56VA power rating meets the load requirements of your application without exceeding thermal limits. Cross-reference the physical dimensions against available space constraints in the final assembly.

Selection Notes

Select this model when a robust, high-isolation transformer is required for industrial environments. The dual primary configuration offers versatility for global voltage compatibility. Consider the 4A current capacity and 12.6V output for servo or control applications. Evaluate the chassis mount requirement against panel space availability. Compare against other DP-241 series variants if different voltage or current ratings are needed.

Part Context

This component belongs to the Two-4-One™ series from Signal Transformer, known for split bobbin technology. The DP-241 series is widely used in heavy-duty industrial applications requiring reliable isolation. Similar models include DP-241-5-10L and DP-241-7-56, which share the same form factor but differ in voltage and current specifications.
