DC100-1000V Din Rail LCD DC Insulation Monitor AIM-D100-TH

With the development of industry, many electrical equipment and plant equipment are powered by DC systems, which have ungrounded positive and negative terminals. For ungrounded (IT) distribution system, insulation resistance should be monitored to ensure the safe operation of the power supply system.

AIM-D100-T series DC insulation monitor can be applied in 10~1000V DC system for on-line monitoring of DC ungrounded system positive and negative pole to ground insulation resistance, and send out warning or alarm signal when insulation resistance is lower than the set value.

The product is based on the principle of unbalanced bridge, which avoids the problem that balanced bridge can not detect the insulation resistance when there are ground faults at both positive and negative poles.

The product can be applied to DC systems such as DC panels of power plants and substations, electric vehicle charging devices, UPS power supply systems, photovoltaic DC systems, energy storage systems and other DC power grids.
