Current Sense Transformers Procurement Notes

Verify the specific manufacturer documentation to confirm the exact package dimensions and pinout configuration before finalizing the PCB layout. Ensure that the selected component matches the required frequency range of 50Hz or 60Hz for your specific application environment. Cross-reference the primary current ratings against your system's peak load requirements to guarantee safe operation within the specified limits.

Current Sense Transformers Selection Notes

Select this component when a high-current sensing solution is needed for low-frequency AC applications. The 1000:1 turns ratio makes it suitable for interfacing with standard measurement circuits. Consider the through-hole mounting style if mechanical stability is prioritized over surface area constraints. Evaluate the 11 Ohm primary resistance against your circuit's voltage drop limitations.

Current Sense Transformers Part Context

This part belongs to the Talema AC Series, which offers a range of current transformers from 5A to 200A. The series is characterized by its cost-effective manufacturing process while maintaining quality standards. Similar parts in the lineup include the AC1150 for lower current applications and other variants tailored to different amperage requirements within the same form factor family.

Current Sense Transformers Replacement Considerations

Direct substitutes within the Talema AC series include models like the AC1150 for reduced current needs. Verify that any alternative maintains the 1000:1 turns ratio and compatible physical footprint for seamless integration without redesigning the host board.
