AIM-D100-T Series Universal DC Insulation Monitor

IM-D100-T series DC insulation monitor can be applied in a 10~1000V DC system, which is used to monitor the insulation resistance of the positive and negative poles to the ground of the DC ungrounded system online, and send out an early warning or alarm signal when the insulation resistance is lower than the set value.

The product is based on the principle of unbalanced bridge, which avoids the problem that the balance bridge cannot detect the insulation resistance when there is a ground fault at the positive and negative poles at the same time.

The products can be used in DC systems such as power generation manufacturers, DC panels of substations, electric vehicle charging devices, UPS power supply systems, photovoltaic DC systems, energy storage systems and other DC power grids.
