Product Description
The CR9521 Series Current Sensors provides a cost effective method for monitoring electrical current. The sensor generates a 0-5 VDC signal proportional to the input AC current. The output signal is average sensing, calibrated to RMS. The sensor is used with process control and industrial instrumentation equipment. Especially suited for OEM applications that require a low cost solution for numerous monitoring locations. The DC output can be connected directly to an analog input connection without additional signal conditioning. Care must be taken to ensure the burden impedance of the instrumentation is greater than 1.0 megohm. The unit will operate with lower burden impedance but at reduced accuracy. Accuracy: +/-0.5 percent full scale (FS). Ripple: 1 percent Max. Signal out: 0-5 VDC. Max. Signal out: 12 VDC. Frequency: 50 to 400 Hz. Insulation class: 600 V. Operating temperature: -30 degree C to + 60 degree C. Storage temperature: -55 degree C to + 85 degree C. Dielectric withstand: 2500 Vrms. Response time: 250 ms. max. 10-90 percent FS. Calibration: Avg. sensing, RMS calibrated. Output load: 1.0 Megohm or greater for rated accuracy.
