Product description:
1, an overview of the
YWG series hall effect sensor can measure arbitrary waveform of current and voltage, output can truly reflect the input current and voltage waveform parameters.Is common for hall effect sensor temperature drift big shortcoming, compensation circuit is adopted to control, effectively reduce the temperature drift of measurement accuracy, ensure accurate measurement;With the characteristics of high precision, convenient installation, low cost.
YWG series hall effect sensors are widely used in variable frequency speed regulating device, inverter device, UPS power supply, communication power supply, electric welding machine, electric locomotive, substation, numerical control machine tool, electrolytic plating, microcomputer monitoring of power grid and the need to isolate detection such as current voltage of the facility.
2, the principle of
YWG - HSD series current sensor is a kind of original and deputy while highly electrical isolation, vice edge reflect measured dc, ac, pulse current, the original edge wave sensors.It has a fast response time, overload ability, good temperature characteristic and continuous adjustable output, stable performance, etc

1) work must be properly connected power supply, output, cannot be wrong answer;
2) for two potentiometer, please do not adjust, if needs calibration, with a small screwdriver slowly rotate to the required precision;
3) the original edge bus temperature should not exceed 60 ℃;
4) when the current bus bar to fill the original edge threading hole, get the best measurement accuracy;
5) using the environment should be no conductive dust and no corrosive action on metals, and damage the insulation gas exists, the height is less than 2500 meters above sea level;
6) test the dc current, current direction and products marked by the arrow direction on the shell, can obtain the positive output.
