The open-core current sensor is designed for cable tie mounting and has a current measuring range of 0.1-40A. It has a high level of accuracy with a class 1 rating and can handle distorted wave-forms with a peak value of = 3. The sensor operates at a rated voltage of 690 VAC/1500 VDC, with a frequency of 50 Hz. It can withstand temperatures ranging from -25 to 70 deg C. The CMS sensors are capable of monitoring and measuring all types of current, including alternating (AC), direct (DC), or mixed (TRMS) currents. Each sensor is equipped with its own microprocessor for signal processing. 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.
