LP-10-2400

Power Transformers Overview

The LP-10-2400 is a board-mount power transformer from Signal Transformer, designed for 50/60 Hz applications. It features a laminated core with semi-toroidal hum-bucking construction to minimize electromagnetic interference. The unit supports dual primary voltage ratings of 115 VAC and 230 VAC, configurable via parallel or series connections. The secondary output provides a center-tapped 10V configuration at 2.4A and a separate 5V winding at 4.8A, delivering a total power rating of 24 VA. It utilizes through-hole mounting for secure PCB integration.

Power Transformers Feature Summary

• Semi-toroidal hum-bucking construction reduces magnetic interference
• Dual primary windings support 115V and 230V AC inputs
• Multi-tap secondary outputs provide flexible voltage options
• Laminated core design ensures stable power conversion

Power Transformers Applications

• Industrial control systems requiring isolated power supplies
• Consumer electronics with multiple voltage rail requirements
• Audio equipment needing low-noise power transformation
• General-purpose AC to DC power supply front ends

Power Transformers Procurement Notes

Verify the specific datasheet version for exact pinout configurations and mechanical dimensions before integration. Confirm that the manufacturing lot complies with current RoHS directives if required by your assembly process. Ensure that the PCB footprint matches the through-hole lead spacing specified in the official package drawing to prevent soldering defects during wave or manual soldering operations.

Power Transformers Selection Notes

Select this component when a compact solution is needed for converting standard line voltages to lower DC rails. The dual secondary taps allow for efficient generation of both 5V and 10V logic levels from a single transformer. Consider the 24 VA power limit to ensure it meets the peak current demands of the downstream circuitry without saturation. The through-hole format is suitable for high-reliability applications where mechanical stress on the connection points must be minimized.

Power Transformers Part Context

This part belongs to the LP series of laminated transformers, which are engineered for board-level power distribution. The series emphasizes compact form factors while maintaining electrical isolation standards. These transformers are commonly used in environments where size constraints limit the use of larger chassis-mounted units, providing a balance between performance and spatial efficiency for embedded power architectures.

Power Transformers Replacement Considerations

Direct substitutes may include other 24 VA laminated transformers with identical 115/230V primary and 10VCT/5V secondary specifications. Verify that any replacement maintains the same semi-toroidal construction to preserve noise characteristics. Ensure the physical footprint and lead pitch are compatible with existing PCB layouts to avoid rework. Cross-reference impedance and insulation voltage ratings to guarantee equivalent safety and performance margins.
