The unit has a primary voltage rating of 115V and 230V. Secondary outputs include 5V at 3A, ±12V at 300mA, and an additional 10.0 KMFD inductance at 15 VDC. The transformer provides a total power capacity of 56VA. Physical dimensions are 76.2 mm in length, 46.5 mm in height, with a unit weight of 770 g.

Feature Summary

• Laminated core construction for standard power transformation
• Dual primary voltage compatibility for international use
• Multiple secondary output configurations including regulated DC support

Applications

• Low power electronic equipment requiring isolated AC/DC conversion
• Audio signal processing circuits utilizing specific secondary voltages
• Industrial control boards needing 5V and ±12V rails

Procurement Notes

Verify the specific datasheet version to confirm RoHS compliance status and exact pinout configuration before integration. Ensure that the thermal management requirements align with the 56VA power dissipation profile. Confirm that the through-hole footprint matches the target PCB design constraints. Check for any specific handling instructions related to the laminated core structure during assembly processes.

Selection Notes

Select this component when a 56VA laminated transformer is required for 50/60 Hz operations. It is suitable for designs needing simultaneous 5V high-current and ±12V low-current supplies. Consider the physical size and weight constraints due to the 770 g mass. Evaluate if the specific secondary winding configuration meets the circuit's voltage regulation needs without additional components.

Part Context

This part belongs to the 14A series of international series transformers manufactured by Signal Transformer. These units are generally utilized in applications demanding reliable power isolation at standard line frequencies. The 14A series typically offers various tap options and core sizes to accommodate different power levels within the low-to-medium range category.

Replacement Considerations

Direct substitutes may include other 56VA laminated transformers from Signal Transformer or compatible manufacturers offering identical 115/230V primary and matching secondary windings. Verify mechanical dimensions and pin spacing to ensure PCB compatibility. Cross-reference electrical ratings to maintain system performance integrity.
