DP-241-8-48L

Overview

The DP-241-8-48L is a laminated core power transformer from Signal Transformer, designed for chassis mounting with wire lead termination. It features dual primary windings rated for 115V and 230VAC input at 50/60Hz frequencies. The secondary output provides 48VCT at a maximum current of 2A, delivering a total power capacity of 100VA. The unit offers 2500Vrms isolation voltage between windings. Physical dimensions are approximately 60.30mm in length, 33.30mm in width, and up to 36.20mm in height, weighing 199.58g. It complies with RoHS3 standards.

Feature Summary

• Utilizes a split bobbin design to ensure superior electrical isolation and minimize capacitive coupling between windings.
• Constructed with a laminated core type to support efficient power transformation for general power supply applications.
• Features dual primary winding configuration allowing flexible operation across standard 115V and 230VAC line voltages.

Applications

• Industrial control systems requiring isolated AC power conversion
• Chassis-mounted power supplies for electronic equipment
• General purpose power distribution in commercial machinery

Procurement Notes

Verify the specific datasheet version (ST-241-L) matches your design requirements before ordering. Confirm that the chassis mounting holes align with your enclosure specifications. Ensure the wire lead termination style is compatible with your circuit board or terminal block connections. Check RoHS3 compliance status if required by your regulatory framework. Validate the 100VA power rating against your peak load demands to prevent overheating.

Selection Notes

Select this component when a 100VA laminated core transformer is needed for chassis installation. The dual primary winding allows compatibility with both 115V and 230VAC mains inputs without rewiring. The split bobbin construction is critical for applications demanding high isolation integrity. Consider the physical dimensions and weight for mechanical integration. This model is suitable where wire leads are preferred over PCB pin headers.

Part Context

This part belongs to the Two-4-One™ series of power transformers manufactured by Signal Transformer. The series is characterized by standardized laminated core designs optimized for reliability and performance. The DP-241-8-48L specifically addresses the need for robust isolation in medium-power applications. It represents a standard offering within the manufacturer's portfolio of surface mount and through-hole magnetics.

Replacement Considerations

Consult the official Signal Transformer datasheet for direct cross-reference part numbers. Verify that any substitute maintains the 100VA rating, 48VCT secondary, and 2500Vrms isolation. Ensure mechanical fitment matches the 60.30mm x 33.30mm footprint. Confirm identical primary voltage ratings and frequency response.
