Overview
The CL2-30-12 is a laminated core power transformer manufactured by Signal Transformer. 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 12 VAC output with a maximum current capacity of 2.5 A, resulting in a total power rating of 30 VA. Designed for through-hole mounting, the unit utilizes solder pin termination for secure PCB integration. Its compact physical dimensions are approximately 47.5 mm in length, 39.6 mm in width, and 39.7 mm in height.
Feature Summary
- Dual primary winding configuration supports flexible input voltage selection between 115 VAC and 230 VAC.
- Laminated core construction ensures stable performance for general-purpose AC to AC power conversion.
- Through-hole mounting style facilitates direct integration into printed circuit boards.
Applications
- General purpose AC power supply circuits
- Industrial control panel instrumentation
- Consumer electronic device power stages
Procurement Notes
Verify the specific datasheet revision to confirm compliance with current RoHS directives and safety certifications such as UL or CE before finalizing procurement. Ensure that the through-hole footprint matches the target PCB layout design. Confirm that the ambient operating temperature range aligns with the intended application environment to maintain the specified 30 VA power rating without derating.
Selection Notes
Select this component when a 30 VA isolation transformer is required for standard 115 VAC or 230 VAC mains inputs. The 12 VAC secondary output is suitable for low-voltage rectification or signal processing stages. Consider the physical size constraints and through-hole assembly requirements during the design phase to ensure adequate clearance on the circuit board.
Part Context
This model belongs to the CL2 series of single-phase power transformers from Signal Transformer. The series is characterized by laminated core designs optimized for cost-effective mass production while maintaining reliable electrical isolation. These transformers are widely utilized in applications requiring standardized voltage step-down capabilities for downstream electronic components.
Replacement Considerations
Direct replacements must match the 30 VA power rating, 115/230 VAC primary input, and 12 VAC secondary output. Verify that substitute parts share identical through-hole pin configurations and comparable physical envelope dimensions to fit existing PCB footprints without mechanical modification.
