AIM-D100-CA series DC insulation monitor can be applied in DC system of 0~1000V, used for on-line monitoring of DC ungrounded system positive and negative pole to ground insulation resistance, when insulation resistance is lower than the set value, it will send out warning or alarm signal.
The product is mainly designed for DC 0~1000V range of electric vehicle charging device insulation monitoring, but also can be applied in energy storage DC, substation DC screen, UPS power supply system, photovoltaic DC system and other DC power grid DC system.
