The GYDCG series DC insulation monitor is based on the RS485 Modbus protocol. This DC insulation monitor is suitable for EV DC charging systems, photovoltaic systems, energy storage systems, DC power grids, and other DC systems under 1000V.
This insulation monitoring device has the function of insulation monitoring start and stop, insulation monitoring can be real-time monitoring of positive and negative poles to the ground insulation resistance. The monitoring result is not affected by DC voltage changing, not affected by the positive and negative poles insulation resistance symmetry.
