Features: 100% brand new and high-quality. The measuring range is 0-100mA which is suitable for most scenarios. High accuracy,the resolution ratio is as precise as 0.1mA and the accuracy grade is 3.0%FS. High sensitivity and few interference was generated if outer electric field is near. High dielectric strength,more safety and let you rest assured. Specification: Detection mode open-and-close CT, on-line installation is particularly convenient. Power source 9VDC 1VDC (or other power supply: 12VDC 1VDC or 5VDC) Working current 20mA max The opening and closing dimension 10 mm (the core can be pierced through a wire of less than 10 mm) Quantity 0.0mA ~ 100mA DC Discriminant power 0.1 mA DC Accuracy level 3.0% FS (23 2 ,70% RH below, conductor in the center of clamp) Turn ratio 1:800 Signal output 25mV/ 1mA, that is,0 ~ 100mA corresponding output 0 ~ 2.5V ( 12VDC power supply: 50mV/ 1mA) Response speed 2 times per second Output line head brown line _ power input is positive;Yellow line _ alarm control end (high potential light);Blue Line _ Output signal is positive;Black line _ common ground end (power input negative and signal output negative, can be shorted with outer shield) Output lead line length 100mm Geomagnetic interference about 3mA The position of the conductor at the center of the opening and closing opening Line voltage DC 600 V below line test Working temperature and humidity -10 ~ 45 ;Under 80% rh Storage temperature and humidity -10 ~ 60 ;Under 70% rh Insulation strength AC 2 kV/ rms (between core and shell) Package List: 1*Main Unit 1*Users Manual Note: 1. As different computers display colors differently, the color of the actual item may vary slightly from the above images. 2. Please allow 1-3mm differs due to manual measurement.
