Overview

The Rogowski coil current sensor operates based on the principle of electromagnetic induction to perform real-time measurement of large AC currents in power grids. It utilizes true RMS and linear compensation technology to isolate and convert the current into a standard DC signal output. Powered by a safe DC 24V supply, SUCH current sensor has high accuracy, strong electrical isolation, enhanced safety, and low power consumption. It is widely applicable in industries such as metallurgy, electroplating, and welding.

Feature

  • Electromagnetic Induction Principle: AC current sensor utilizes the principle of electromagnetic induction to perform real-time measurement of large AC currents in power systems.
  • True RMS and Linear Compensation: Employs true RMS detection and linear compensation technology to accurately reflect actual current, even with distorted waveforms.
  • Isolated Signal Output: Converts the measured current into a standard DC output signal with high electrical isolation for enhanced safety.
  • Safe DC Power Supply: Operates on a safe DC 24V power supply, suitable for industrial environments with stringent safety requirements.
  • High Accuracy: Delivers precise current measurement over a wide dynamic range, ensuring reliable monitoring and control.
  • High Isolation: Effectively separates the primary current circuit from the output signal circuit, reducing interference and enhancing protection.
  • Low Power Consumption: Designed for energy efficiency with power consumption less than 0.5W, reducing thermal impact and improving durability.
  • Industrial-Grade Safety: Built to withstand harsh operating environments with robust insulation and overvoltage protection.
  • Wide Application Fields: Ideal for use in metallurgical equipment, electroplating power supplies, welding systems, and other high-current industrial applications.
