GYDCG-UB1K-ARH is a DC-to-Ground insulation monitoring module based on the principle of unbalanced bridge, which has monitoring and protection functions in one. It can monitor the insulation resistance value of the positive and negative poles of the DC floating system to the ground, ranging from 1KΩ~10 MΩ; at the same time, it can also detect the DC voltage value, ranging from 100V to 1000V
