CT1200

Overview

The CT1200 is a current sense transformer manufactured by Amgis, LLC. It features a non-invasive solid core design with through-hole PC pin termination. The device supports a primary current rating of 200 A and operates at frequencies of 50/60 Hz. It provides a current ratio of 1000:1 and has a secondary DC resistance (DCR) of 11 Ohms. The physical dimensions are 55.60 mm in length and 20.60 mm in width, with a maximum height of 55.60 mm. The unit weighs approximately 150.14 grams.

Feature Summary

• Non-invasive solid core construction for direct conductor insertion
• Through-hole mounting with PC pin termination style
• High current sensing capability up to 200 A
• Standard 50/60 Hz frequency operation

Applications

• AC current monitoring in power distribution systems
• Protection circuits requiring high-current isolation
• Energy metering applications for mains frequency currents

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct configuration. Confirm that the required current rating and frequency range match the application specifications. Check RoHS compliance status if environmental regulations apply. Ensure the through-hole footprint dimensions align with the PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when a non-invasive solution for high AC current measurement is required. The 200 A rating suits heavy-duty industrial or commercial power lines. The 1000:1 ratio determines the signal level for downstream processing. Verify that the 11 Ohm secondary resistance is compatible with the connected load or amplifier input impedance.

Part Context

The CT1200 belongs to the CT series of current sense transformers from Amgis, LLC. This series focuses on toroidal magnetic components for power electronics. The part is designed for robust performance in standard AC environments. It serves as a passive sensing element within larger power management or monitoring assemblies.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Consult the manufacturer for direct equivalents or cross-reference based on identical electrical parameters such as 200 A rating, 1000:1 ratio, and through-hole package type.
