Recently Acrel DC insulation monitoring meters have obtained CE certification. The specific model type is AIM-D100-TH, AIM-D100-CA, AIM-D100-CAI,AIM-D100-ES,AIM-D100-ESL,AIM-D200-TH, AIM-D200-CA.

Among of them, AIM-D100-CA series DC insulation monitor can be applied in DC system of 0~1000V, AIM-D100-T in 10~1000VDC. They are 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 products are mainly designed for 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.
