The KCT-L series true RMS current sensor is a high-precision open-loop current measurement device based on the Hall effect principle, integrating true RMS measurement, industrial grade electrical isolation, 4-20mA standard analog output, and split hinge structure. Specially designed for complex industrial environments and new energy applications, it can accurately measure AC, DC, and pulse currents, ensuring reliable monitoring and energy efficiency management of the system.
The KCT-L series is a detachable Hall effect current sensor that uses open-loop measurement principle to achieve electrical isolation between the primary and secondary circuits, with a maximum isolation voltage of 5kV. This series of sensors supports multiple rated current measurement ranges (50A to 600A) and 4-20mA analog output, with a power supply voltage of+12V or+24V and a power consumption of only 35mA, suitable for integration with various automation equipment and power monitoring systems. The product has a built-in integrator function (some models) that can calculate the accumulated charge of current over time, supporting energy statistics and predictive maintenance scenarios. Its split hinge design facilitates installation and replacement without cutting off the circuit, reducing maintenance costs and downtime.
