Wiring diagram with current output
* High detection precision
Detection range up to 0.5～100m; Low end detection deviation less than15uA;
* Easy to use
Adopts perforative input, it is very easy for users to install and debug;
* Strong overload ability
Can withstand high current impulse; It can also be tested in high voltage environment, avoid the inescapable weakness of connection detection;
* Wide power adaptation
The product needs only single power supply, at the same time the influence of the power supply down-deflection is small, solved the problem of traditional (Hall magnetic balanced principle) dual power source operation and great influence of power supply down-deflection.
* High stability
The product adopts various shielding measures, very effective inhibition of spatial interference to ensure the accuracy and stability of testing.
* Excellent temperature characteristics
Every 1℃ changes of the temperature, the output drift is less than 400ppm;
* Excellent characteristic of zero point
Different from the principle of the traditional (hall magnetic equilibrium principle), with excellent characteristic of zero point.
The input/output/power supply of this product adopts the surge suppression, enable the product to meet three levels of anti-interference level of the 《IEC61000-4-5(GBT17626.5)》 standard.
* High safety performance
Using contactless input, make the input voltage isolation up to 35KV(not the bare wire situation). Greatly improved the safety in using this product.
