AX-0500

Current Sense Transformers Overview

The AX-0500 is a through-hole current sense transformer manufactured by Talema Group LLC, designed for 50Hz and 60Hz applications. It features a primary input current rating of 5A and a turns ratio of 500:1. The device provides an internal burden resistance of 100Ω and offers 2.5kV isolation voltage. Operating within a temperature range of -40°C to +120°C, it utilizes a fully potted construction optimized for printed circuit board mounting.

Current Sense Transformers Feature Summary

• High output voltage capability within a compact package design
• Good linearity maintained across the specified current range
• 2.5kV isolation voltage for enhanced safety
• High saturation current handling capacity

Current Sense Transformers Applications

• Power monitoring systems
• Current sensing circuits
• Industrial control panels

Current Sense Transformers Procurement Notes

Verify that the required operating frequency matches the 50Hz or 60Hz specification. Confirm that the system's primary current does not exceed the 5A rated input. Ensure the PCB layout accommodates the through-hole termination style and center hole dimensions for the current-carrying line. Check thermal requirements against the -40°C to +120°C operating range.

Current Sense Transformers Selection Notes

Select this component when a 500:1 ratio is required for a 5A primary current. Consider the 100Ω internal burden if external resistors are not desired. The high saturation current makes it suitable for applications with potential transient loads. Verify that the 2.5kV isolation meets the safety standards of the target equipment.
