DCG series DC insulation monitor is based onRS485 Modbus protocol, suitable for EV DCcharging system, photovoltaic system, energystorage system, DC power grid and other DCsystems under 1000V.
This device has the function of insulationmonitoring start and stop, insulationmonitoring can be real-time monitoring ofpositive and negative poles to the groundinsulation resistance, the monitoring result isnota affected by DC voltage changing, is notaffected by the positive and negative polesinsulation resistance symmetry.
