Features Non-contact Measurement: The Rogowski coil transformer consists of a coil and a handle. There is no exposed metal conductor in the coil part, and the non-contact measurement is safe and reliable. Toroidal Coil: A toroidal coil in which the transformer is evenly wound on a non-ferromagnetic material, with no hysteresis effect, almost 0 phase error, no magnetic saturation, and extremely high linearity. High-accuracy: The coil transformer has a wide measurement range, high accuracy and strong reliability, and the response frequency bandwidth is 0.1Hz-1MHz. Soft and Flexible: The detector is small in size, light in weight, beautiful in appearance, soft and flexible, suitable for narrow environments and places with dense cables. Mainly Used for Detection: AC current detector is mainly used to detect AC leakage current, large current, high-order harmonic current (up to 400 times), complex waveform current, transient impact current, phase, electric energy, power factor, etc. Specification: Item Type: Flexible Coil Current Sensor Model: ETCR150FA Material: ABS Application: Electronics industry, power communications, equipment manufacturing, power grid maintenance Coil Diameter: Approx. 7.5mm / 0.3in Range: 0A~10000A~higher Resolution: 10mA Accuracy Class: ±1.0%FS (50Hz/60Hz; 23℃±2℃, below 70%RH, the wire is at the center of the coil) Phase Error: ≤0.1°(50Hz/60Hz; 23℃±2℃) Output Interface: Approx. 3.5mm / 0.1in audio frequency plug/BNC plug/tap (optional) cable length: Approx. 2m / 6.6ft Electric Field Interference: No hysteresis effect, no interference from external electric field Wire Position: The tested wire is at the center of the coil, and the position error affects ≤±0.3%FS Current Frequency: 45Hz~70Hz (frequency of measured current) Response Frequency: 0.1Hz~1MHz Line Voltage: Line test below AC 1000V Working Temperature and Humidity: -20℃~50℃; below 80%rh Storage Temperature and Humidity: -10℃~60℃; below 70%rh Dielectric Strength: AC 2000V/rms (both ends of the coil unlocked and expanded) Suitable for Safety Standard: CAT IV 600V, CAT Ⅲ 1000V Package List: 1 x Coil Current Sensor Package List 1 x Coil Current Sensor
