AC1025

Current Sense Transformers Overview

The Talema Group LLC AC1025 is a low-cost current sense transformer designed for 50/60Hz applications. It features a primary current rating of 25 A and a turns ratio of 1000:1. The device has a DC resistance (DCR) of 48 Ohms and is intended for use with a 100 Ohm burden resistance. It utilizes a through-hole mounting style.

Current Sense Transformers Feature Summary

• Provides accurate current sensing for overload detection and ground fault protection
• Designed for integration into analog-to-digital circuits and metering systems
• Manufactured in ISO-9001, TS-16949, and ISO-14000 certified facilities

Current Sense Transformers Applications

• Sensing overload current
• Ground fault detection
• Metering
• Analog to Digital Circuits

Current Sense Transformers Procurement Notes

Verify the specific manufacturer designation, as Talema products are often distributed under the Nuvotem brand. Confirm that the required burden resistance matches the design specification of 100 Ohms to ensure accurate signal conversion. Ensure the application frequency aligns with the 50/60Hz operational range defined in the datasheet.

Current Sense Transformers Selection Notes

Select this component when a 25 A primary current capacity is required for low-frequency power monitoring. The 1000:1 turns ratio dictates the secondary output magnitude relative to the primary input. Consider the physical dimensions of 30.20 x 14.30 x 30.2 mm for PCB layout constraints and verify compatibility with through-hole assembly processes.

Current Sense Transformers Part Context

The AC1025 belongs to the AC Series of low-cost current transformers from Talema Group LLC. This series offers primary current ratings ranging from 5 A to 200 A, providing scalable solutions for various power monitoring needs. All units in this family share a consistent 1000:1 turns ratio and are optimized for cost-effective mass production.

Current Sense Transformers Replacement Considerations

Compatible substitutes within the same series include the AC1020 (20 A), AC1030 (30 A), and AC1015 (15 A). These alternatives maintain identical electrical characteristics such as the 1000:1 ratio and 100 Ohm burden requirement, differing only in their maximum primary current ratings.
