Procurement Notes
Verify the specific ordering suffix against official manufacturer documentation to confirm lead time, packaging quantity, and pricing details. Ensure the component meets required isolation voltage standards for the target application environment before finalizing procurement orders.
Selection Notes
Select this model for applications requiring non-invasive current measurement up to 200 A AC. Confirm that the operating frequency falls within the 50 Hz to 400 Hz range. Evaluate the need for fly leads versus other termination options based on PCB or panel layout constraints.
Part Context
This component belongs to the CR Magnetics current sense transformer series, designed for precise AC current monitoring. It serves as a passive sensing element in larger power management or protection assemblies, providing isolated feedback signals proportional to the primary conductor current.
Replacement Considerations
Cross-reference part numbers such as CR2RL-201 or CR5RL-201 for alternative configurations within the same product family. Verify pinout compatibility and electrical specifications before substituting to ensure system integrity.
FAQ
