This product is used for signal isolation and acquisition of low-voltage relay protection ; The current signal during short-circuit fault of the system is converted into a signal suitable for weak current circuit through the transformer, and the accurately transmitted to the electronic circuit based on microprocessor ;
The product uses a special composite magnetic core with high permeability and small residual magnetism ,which can effectively prevent the first wave distortion caused by the “excitation inrush current” generated during the opening and closing test .
PCB mounting method ,directly soldered on the circuit board;
High permeability ,small magnetic leakage and excellent consistency ;
Strong overload capacity ,can withstand 20-40 times the rated current instantaneous impact without saturation ;
30% DC component waveform can be superimposed without distortion;
Various shape structures are available .
