AIM-D200-CAI DC Insulation Monitor

AIM-D200-CAI DC insulation monitor can be used in 100 ~1000V DC systems for online monitoring of the insulation resistance of the positive and negative poles of an ungroundedDC system. When the insulation resistance is lower than the set value, it will send warning or alarm signal.

Product Description

Overview

Brand：Acrel

Place of Origin：China

Application: EV Charger

With the development of industry, many electrical equipment and factory equipment are powered by DC systems, and the positive and negative poles of the DC system are not grounded. For ungrounded (IT) power distribution systems, insulation resistance should be monitored to ensure the safe operation of the power supply system.

AIM-D200-CAI DC insulation monitor can be used in 100 ~1000V DC systems for online monitoring of the insulation resistance of the positive and negative poles of an ungroundedDC system. When the insulation resistance is lower than the set value, it will send warning or alarm signal.

The product is based on the unbalanced bridge principle, which avoids the problem that the balanced bridge cannot detect the insulation resistance when ground fault at both the positive and negative poles.

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.
