CT-1100

Overview

The CT-1100 is a current sense transformer manufactured by Amgis, LLC, designed for monitoring electrical currents ranging from 5 to 200A. It features a non-invasive solid core design suitable for through-hole mounting. The component operates at frequencies of 50/60Hz with a primary current rating of 100A. Key electrical specifications include a secondary resistance (DCR) of 21.3 Ohms and a maximum seated height of 1.752 inches (44.50mm). The unit provides primary-to-secondary insulation and supports wide operating temperature ranges typical for the CT Series.

Feature Summary

• Non-invasive solid core construction for direct current monitoring
• Primary-to-secondary insulation for circuit isolation
• Through-hole mounting configuration for PCB integration

Applications

• Electrical current monitoring in power systems
• Industrial control circuits requiring current sensing
• Power supply feedback loops

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct pinout and insulation ratings. Confirm that the 100A primary current rating aligns with the application requirements. Check RoHS compliance status if environmental regulations apply. Ensure the through-hole footprint matches the PCB layout dimensions provided in the mechanical drawings.

Selection Notes

Select this component when a non-invasive current sensing solution is required for 50/60Hz applications. The 100A rating suits moderate to high current monitoring tasks. Consider the 21.3 Ohm secondary resistance for signal conditioning circuit design. The solid core design eliminates the need for conductor splitting during installation.

Part Context

The CT-1100 belongs to the Amgis CT Series, which covers current ratings from 5 to 200A. This series emphasizes dry-type construction and wide operating temperature capabilities. It serves as a specialized sensor within the broader category of current transformers, distinct from general-purpose toroidal inductors offered by the same manufacturer.

Replacement Considerations

Cross-reference part numbers such as CT-1200 for higher current ratings or CT-1040 for alternative configurations within the Amgis lineup. Verify that substitute components maintain identical primary current ratings and secondary resistance values to ensure circuit compatibility.
