S50 1200A 1mv/A and 1mA/A output AC Current Clamp on CT

voltage output current clamp sensor

The round jaw design on the S50 Series AC current clamp on CT along with the high content nickel metal core makes them well suited for power quality applications where high accuracy and low phase shift along with wide frequency are important from 10Hz to 10MHz. Measurement range is 1mA to 1200A. The S50 is a general purpose 1200A AC current clamp on CT designed for use with DMMs, power loggers and energy meter calibration instruments that have a current input. It has a 1000:1 ratio and output of 1mA per amp or 1mV per amp measured in the jaw. The S50 clamp on CT has an integral 2.5m lead terminated. The rounded jaw design on this current clamp makes it well-suited for power applications where high accuracy 0.1% and low phase shift and wide frequency response are important. .
