CL2-50-12

Overview

The CL2-50-12 is a laminated core power transformer designed for board mounting applications. It features dual primary windings rated for 115 VAC and 230 VAC operation at 50 Hz or 60 Hz frequencies. The secondary winding provides a single output of 12 VDC with a current rating of 4.2 A, resulting in a total power capacity of 50 VA. The component utilizes through-hole termination for secure PCB integration. Physical dimensions include a length of 76.2 mm, width of 46.5 mm, and height of 46.5 mm. It weighs approximately 200 grams and supports industrial environmental conditions.

Feature Summary

• Dual primary winding configuration enables compatibility with both 115 VAC and 230 VAC input standards.
• Laminated core construction ensures efficient magnetic coupling and stable voltage regulation under load.
• Through-hole mounting style provides robust mechanical attachment to printed circuit boards.

Applications

• Industrial control panel power supplies
• General purpose AC to DC conversion circuits
• Electronic equipment requiring isolated low-voltage DC power

Procurement Notes

Verify the specific datasheet version provided by Signal Transformer or authorized distributors to confirm compliance with current RoHS directives and safety certifications such as UL or CE. Ensure that the thermal management requirements of the host system can accommodate the heat dissipation characteristics of this 50 VA unit during continuous operation. Cross-reference the pinout diagram with the target PCB layout to prevent installation errors.

Selection Notes

Select this model when a reliable, high-current 12 VDC supply is required from standard mains voltages. The 50 VA rating supports loads up to 4.2 A, making it suitable for moderate power applications. Consider the physical footprint and through-hole requirement against available board space and assembly methods. Evaluate the operating frequency range to ensure compatibility with the local power grid standards.

Part Context

This component belongs to the CL2 series of laminated core transformers manufactured by Signal Transformer, now part of Bel Fuse. The series is characterized by its robust construction and suitability for general-purpose power transformation tasks. These units are widely used in industries requiring dependable isolation between primary mains and secondary low-voltage circuits.

Replacement Considerations

Direct substitutes must match the 50 VA power rating, 12 V secondary output, and 4.2 A current capacity. Verify that alternative models support the same 115/230 VAC dual primary inputs and maintain identical through-hole mounting dimensions. Check for equivalent safety approvals and operating temperature ranges before substitution.
