AP-1000

Current Sense Transformers Overview

The AP-1000 is a through-hole current sense transformer manufactured by Talema Group LLC. It features a 10 A primary current rating and a maximum secondary impedance of 70 Ohms. The device utilizes a 1000:1 turns ratio for precise current sensing applications. Its physical dimensions are 17.2 mm in length, 9.53 mm in width, and 20.4 mm in height.

Current Sense Transformers Feature Summary

• Provides precise current sensing with a high 1000:1 turns ratio
• Designed for through-hole mounting on printed circuit boards
• Rated for 10 A primary current with 70 Ohm maximum secondary impedance

Current Sense Transformers Applications

• Current monitoring in power supply circuits
• Overcurrent protection systems
• Feedback control loops in electronic devices

Current Sense Transformers Procurement Notes

Verify the specific manufacturer designation, as Talema operates under various brand names including Nuvotem Talema and Alphamag/Talema. Confirm that the required 1000:1 ratio and 10 A rating match the application requirements. Ensure the through-hole package dimensions fit the target PCB layout. Check for any specific UL or VDE certification needs if applicable to the end product.

Current Sense Transformers Selection Notes

Select this component when a high isolation ratio is required for accurate current measurement. The 10 A rating suits moderate to high-current applications. Consider the 70 Ohm impedance limit to ensure compatibility with the downstream sensing circuitry. The through-hole format is suitable for robust mechanical connections where surface-mount options are insufficient.

Current Sense Transformers Part Context

This part belongs to the family of current sense transformers used for isolated current detection. Unlike power transformers, these devices are optimized for signal fidelity rather than power transfer. They typically operate within a frequency range of 2 Hz to 1 MHz, supporting both AC and pulsed DC current measurements in industrial and consumer electronics.
