The open-core current sensor is designed for cable tie mounting and has a current measuring range of 0.1-20A. It has a high level of accuracy, with a class 1 rating and a peak value of the distorted wave-form at = 6. The sensor can handle a rated operational voltage of 690 VAC/1500 VDC, with a frequency of 50 Hz. It operates within a temperature range of -25 to 70 deg C. The CMS sensors are capable of monitoring and measuring all types of current - alternating (AC), direct (DC), or mixed (TRMS) currents. Each sensor is equipped with its own microprocessor for processing the signal. The maximum diameter of the cable that can be used with this sensor is 9.6 mm. The dimensions of the sensor are 29Hx17.4Wx41D mm.
