ACT07-4319

Current Sense Transformers Overview

The ACT07-4319 is a current sense transformer manufactured by Allied Components International, designed for through-hole mounting. It features a primary-to-secondary turns ratio of 1:2500 and supports a rated input current of 30 A. The component operates within a frequency range of 50 Hz to 60 Hz. The maximum DC resistance (DCR) on the primary side is specified as 155 Ohms. This magnetic component is intended for applications requiring precise current monitoring in low-frequency AC environments.

Current Sense Transformers Feature Summary

• Provides electrical isolation between primary and secondary circuits for accurate current measurement
• Engineered with a high turns ratio to facilitate signal conditioning for downstream sensing electronics
• Constructed for reliable performance in standard through-hole assembly processes

Current Sense Transformers Applications

• AC power supply current monitoring
• Industrial equipment protection circuits
• Low-frequency inverter output sensing

Current Sense Transformers Procurement Notes

Verify that the required operating frequency aligns strictly with the 50 Hz to 60 Hz specification. Confirm that the peak primary current does not exceed the 30 A rated limit to prevent saturation or thermal issues. Ensure the PCB layout accommodates the through-hole package dimensions and maintains adequate clearance for the 155 Ohm primary winding resistance characteristics.

Current Sense Transformers Selection Notes

Select this component when a fixed 1:2500 transformation ratio is necessary for specific sensor interface requirements. Consider the 155 Ohm primary impedance when calculating voltage drop and power loss in the primary circuit. Evaluate the physical size constraints for through-hole installation against available board space. Compare alternative models only if different frequency ranges or current ratings are required.
