Feature:1. Clamp current sensor for AC leakage current, current, high harmonic current, phase, electric energy, power, power factor and other detection.2. The use of clamp structure, no need to disconnect the tested circuit, easy to carry, safe and simple operation, fast, safe and reliable.3. It can be connected to industrial control devices, oscilloscopes, harmonic analyzers, cable line tester, double clamp ground resistance testers, cable fault testers, and power quality analyzers.4. Adapt to a variety of output interfaces, such as 3.5mm audio plug, BNC plug, 4.0mm double banana plug, aviation plug, bare wire.5. Permalloy core is more accurate for testing small current. Has strong anti interference ability, to ensure the accuracy and stability of the measurement.Specification:Item Type: Clamp Current Transformer Material: ABS+PermalloyColor: As shown in the pictureModel: ETCR070Application: AC current, high harmonic current, phase, electric energy, power, power factor and other industrial electricity and electricity metering detection.Industrial control device, oscilloscope, harmonic analyzer, cable line tester, double clamp ground resistance tester, cable fault tester, power quality analyzer.Input Current Range: 0mA~1000A; output signal: mA/A, mV/AOutput Interface: 3.5mm audio plug/BNC plug/4.0mm double banana plug/aviation plug/bare wire (optional)Cable Length: Approx. 2m / 6.6ftJaw Size: 70mm / 2.76inWorking Temperature: -15C~60CTransformer modelInput CurrentOutput SignalFrequencySecondary loadAccuracy classETCR0700mA~300A100mA10Hz~100kHz0~10A5000~100A500~1000A50.50mA~400A200mA0.50mA~600A600mA0.50mA~1000A250mA0.51A~1000A1mV/A100k1.Package List:1 x Clamp Current Transformer Note:1.
