YDG-HTD Hall Current Sensor

u  Introduction
YDG-HTD-4-50Aac Hall Effect Current Transducer is equipped with supplementary circuit to reduce the temperature drift which is common among other hall-effect transducers. It has greatly improved the measuring accuracy and achieved easy installation while reducing the cost.
YDG Series Hall-effect Transducer is widely applied in establishments where isolated current need to be examined, such as inversion equipment, UPS power supplier, communication power supplier, electric wielding machines, electric motor-vehicle, transformer substation, digital-controlled lathe, plating, micro-machine monitoring, electric-network monitoring, etc.

u  Safety Notice
²  Power supply and output terminals should be connected correctly;
²  Avoid to adjust the two potentiometers; use small screwdriver to screw it slowly to the precision when necessary;
²  The temperature of ary generatrix should not over 60℃;
²  The best measuring precision is obtained when the ary hole is full of current generatrix.
²  The operating environment allows no electric dust or gases that corrodes metal or destroys insulation. The altitude is less than 2500m.

To measure the DC current, positive output is obtained when the current direction is the same as the arrow marked on the shell of the product. 0 level1 lfo3; tab-stops:list 0cm\'>²     Power consumption：＜1VA
