AC1100

Current Sense Transformers Overview

The Talema Group LLC AC1100 is a through-hole current sense transformer designed for measuring alternating currents up to 100 Amperes. It operates within a frequency range of 50Hz and 60Hz, making it suitable for standard power line applications. The component features a primary DC resistance (DCR) of 21.3 Ohms maximum. With a current ratio of 1000:1, it provides accurate signal isolation and scaling for monitoring circuits. The unit utilizes a through-hole mounting style with dimensions of 1.752 inches in length and 0.563 inches in width.

Current Sense Transformers Feature Summary

• Provides electrical isolation between high-current primary circuits and low-voltage secondary sensing loads
• Supports standard 50Hz and 60Hz power frequencies for reliable operation in utility-grade environments
• Utilizes a through-hole package configuration for secure mechanical attachment to printed circuit boards

Current Sense Transformers Applications

• Industrial equipment current monitoring systems
• Power supply output measurement circuits
• Electrical metering and energy management devices

Current Sense Transformers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure compatibility with required pin configurations or tolerance levels. Confirm that the through-hole footprint matches the target PCB layout dimensions precisely. Request updated datasheets directly from Talema Group LLC distributors to validate the 100A rating and 21.3 Ohm DCR specifications for the exact batch being procured.

Current Sense Transformers Selection Notes

Select this component when precise isolation is required for currents up to 100A at standard power frequencies. Ensure the PCB design accommodates the specified through-hole dimensions and spacing. Consider the 1000:1 ratio to determine appropriate burden resistor values for the downstream analog-to-digital converter or amplifier stages to maintain signal integrity.
