S120 30A/300A/3000A 200kHz BANDWIDTH HIGH PRECISION OSCILLOSCOPE CURRENT MEASUREMENT CLAMP
INTRODUCE
The S120 current clamp is a high performance AC clamp on current transformer probe with excellent transformation and low phase shift. The high quality magnetic permalloy core and uniform windings provide for accurate measurements up to 3000AAC/2000AAC/1000AAC/500AAC. The "ring type" jaw permits good magnetic conduction and cable positionings. Provide excellent RMS capabilities and reliable signal reproduction.
The S120 clamp on ct is well suited for power quality applications where high accuracy and low phase shift along with wide frequency from 10Hz to 2MHz are important. Measurement range is 100mA to 3000A.
The S120 clamp on current transformer is a general purpose 3000A AC clamp current probe transformer designed for use with DMMs & BNC, cable fault analysis and loggers instruments that have a current input. It has a 1000:1 or 2000:1 ratio and output of 1mA per amp or 1mV per amp measured in the jaw. The S120 has an integral 2.5m or 5m lead terminated. The rounded jaw design on this clamp probe makes it well-suited for cable fault analysis applications where high accuracy and low phase shift and wide frequency.
All of our CT current clamp are strictly comply IEC60044-1, IEC 61869-2, ANSI/IEEE C57.13, GB1208-2006, GB/T 20840.1-2010, GB/T 20840.2-2014, GB/T 22071.1-2018, IEC/EN61010-2-032, IEC/EN 61010-2-031.
