CL2-40-24

Overview

The Signal Transformer CL2-40-24 is a laminated core power transformer with a maximum power rating of 40VA. It features dual primary windings supporting 115V and 230V input voltages, and a single secondary winding providing 24V at a maximum current of 1.66A. The unit utilizes chassis mounting and offers 4000Vrms isolation voltage. Physical dimensions are 79.40mm in length, 54.40mm in width, and a maximum installation height of 68.20mm. The component weighs approximately 725.7g and supports both soldering and quick-connect termination styles.

Feature Summary

• Dual primary winding configuration for versatile 115V or 230V AC input compatibility
• High isolation capability rated at 4000Vrms between windings
• Robust laminated core construction designed for chassis mounting applications

Applications

• Industrial control panel power supplies
• Machinery internal power distribution systems
• Electronic equipment requiring isolated low-voltage DC conversion

Procurement Notes

Verify the specific datasheet version (ST-CL2-CM) to confirm compliance with current RoHS3 standards and REACH regulations before procurement. Ensure that the required termination style matches available options, as the component supports both soldering and quick-connect methods. Confirm that the chassis mounting holes align with the specified physical dimensions of 79.40mm by 54.40mm to prevent installation issues during assembly.

Selection Notes

Select this model when a 40VA capacity is sufficient for the load requirements. The dual primary design allows operation in regions utilizing either 115V or 230V mains without needing different part numbers. Consider the physical size constraints carefully, as the height reaches up to 68.20mm. This transformer is suitable for Class 2 circuits where the specified isolation voltage provides adequate safety separation from primary line voltages.

Part Context

This component belongs to the CL2 series of power transformers manufactured by Signal Transformer. The series is characterized by laminated core designs intended for general-purpose power conversion tasks. The CL2-40-24 specifically addresses applications requiring a 24V output derived from standard high-voltage AC inputs, fitting into the broader category of industrial-grade electrical isolation components.
