Measuring type transformer
Good linearity, high precision, wide operating range.
The primary circuit through a series of current limiting resistance and then the voltage is turned into current.
After the transformer secondary output current signal, the sampling resistance is turned into the required voltage signal. The input and output are pins. Exterior material (ABS or PBT) meets UL94-V0.
