CT-1040

Overview

The CT-1040 is a current sense transformer manufactured by Amgis, LLC, designed for non-invasive current monitoring in AC power systems. It features a solid core construction suitable for through-hole mounting on printed circuit boards. The component operates at standard frequencies of 50/60Hz and supports a primary current rating of 40A. It provides a precise 1000:1 current transformation ratio, stepping down the high primary current to a measurable secondary level. The device exhibits a DC resistance of 49.3 Ohms on the secondary winding and utilizes PC pin termination for secure board integration.

Feature Summary

• Non-invasive solid core design enables direct wire insertion without circuit interruption
• High isolation capability ensures safety during high-current monitoring applications
• Through-hole PC pin termination provides robust mechanical stability on PCBs

Applications

• AC power supply current monitoring and protection circuits
• Industrial motor drive feedback systems
• Inverter output current sensing
• Power quality analysis equipment

Procurement Notes

Verify that the specific order matches the Amgis, LLC manufacturer designation and the exact model number CT-1040. Confirm the package type corresponds to the through-hole configuration with PC pins as specified. Ensure the frequency range requirement aligns with the 50/60Hz operational specification before finalizing procurement to avoid compatibility issues with higher frequency applications.

Selection Notes

Select this component when a non-invasive solution is required for monitoring AC currents up to 40A. The 1000:1 ratio makes it suitable for interfacing with low-voltage measurement circuits or microcontroller ADC inputs. Consider the physical dimensions and through-hole mounting requirements against available PCB space. This part is appropriate for standard utility frequency applications rather than high-frequency switching environments.

Part Context

The CT-1040 belongs to the CT series of current sense transformers produced by Amgis, LLC. This series focuses on providing reliable magnetic coupling for AC current measurement in various power electronics applications. The product line includes variants with different current ratings, such as the CT-1200 rated for 200A, allowing engineers to scale their sensing solutions based on specific load requirements while maintaining consistent form factors and interface standards.

Replacement Considerations

Direct cross-replacement requires matching the 1000:1 ratio, 40A rating, and 49.3 Ohm secondary resistance. Verify that any substitute component supports the same 50/60Hz frequency range and through-hole PC pin termination style. Physical footprint compatibility must be confirmed to ensure proper PCB hole alignment and mechanical fit within the existing assembly constraints.
