Q40 Ratio 500A / 500mA Split Core Amp Current Sensor for Metering 40mm 0.5 Class


The GFUVE Split Core Amp Current Sensor Q40-3 features 40 mm jaw size and distinct jaw shapes which can hook around the conductor easily. Q40-3 sensors are an excellent probe to be used in power and low level current measurement applications.

A common form of current clamp comprises a split ring made of ferrite or soft iron. A wire coil is wound round one or both halves, forming one winding of a current transformer. The conductor it is clamped around forms the other winding. Like any transformer this type works only with AC or pulse waveforms, with some examples extending into the megahertz range.

Clamp-on Current Transformer Current Clamp is a high-precision AC current converter, and can meet a variety of measuring instruments, It can be used along with many kinds of instruments and devices, such as energy meter spot calibrator, multifunctional meter, oscilloscope, digital multimeter, dual clamp Ground resistance tester, dual clamp phase volt ammeter.

The GFUVE clamp-on current transformer is very popular with our customers due to its fast and easy installation Produced with amorphous silicon core or permalloy core, this product features small size, high precision good stability and good anti-interference This product is widely used for measuring power and energy in the fields of electric power, communication and monitoring system. Besides the high precision and the small phase error this clamp-on current transformer can be used to measure a wide variety of electric parameters without disconnecting the exiting electric system.
