Product Overview

Description



Product Description


GYDCG-UBCW2K series 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 0Ω to 10MΩ; at the same time, it can also detect the DC voltage value, ranging from 0V to 2000V.
The insulation resistance monitoring can only be realized when the DC voltage is between 100V and 2000V. When the DC voltage is less than 100V, or the insulation monitoring is not enabled, the insulation resistance read is 65535 (invalid number). When the measured value is greater than 10MΩ, the value received by the communication is 60000 (infinity).
