Overview
The CL2-10R-12 is a laminated core power transformer manufactured by Signal Transformer. It features a primary voltage rating of 115 VAC and 230 VAC, with a secondary output of 12 V at 830 mA. The unit has a 10 VA power rating and operates at 50/60 Hz frequencies. Designed for through-hole mounting, it utilizes a Class 2 insulation system. The component is shielded to minimize electromagnetic interference and is suitable for board mount applications requiring reliable AC-to-DC conversion in industrial control circuits.
Feature Summary
- Laminated core construction for efficient magnetic flux transfer
- Shielded design to reduce electromagnetic interference
- Class 2 insulation safety rating
- Through-hole mounting configuration
Applications
- Industrial control systems
- Power supply units
- Electronic equipment requiring isolated AC voltage transformation
Procurement Notes
Verify the specific datasheet version before procurement to ensure compliance with current safety standards and RoHS directives. Confirm that the through-hole footprint matches the target PCB layout dimensions. Check for any recent product change notices regarding material composition or manufacturing location changes that may affect long-term availability or performance characteristics.
Selection Notes
Select this component when a 10 VA isolation transformer is required for low-power applications. Ensure the input voltage matches either 115 VAC or 230 VAC configurations. Consider the physical size constraints due to the through-hole mounting style. Verify that the 12 V secondary output meets the load requirements of the downstream circuitry without exceeding the 830 mA current limit.
Part Context
This part belongs to the CL2 series of power transformers from Signal Transformer. The series offers various voltage combinations and power ratings tailored for general-purpose isolation tasks. The CL2-10R-12 specifically addresses needs for compact, shielded transformers in environments where electromagnetic compatibility is critical. It serves as a fundamental building block for converting standard mains voltages to lower, safer levels for sensitive electronics.
Replacement Considerations
Consult official cross-reference lists for direct equivalents. Ensure substitute parts maintain identical electrical ratings, including 10 VA power, 12 V secondary, and 830 mA current capacity. Verify mechanical compatibility, particularly the through-hole pin spacing and overall envelope dimensions. Confirm that replacement components also meet Class 2 insulation and shielding requirements.
