General
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 monitoring should be performed to ensure the safe operation of the power supply system .
AIM-D500-CA DC system insulation monitoring device can be used in 50~400V DC systems. It can monitor up to 1000V with ACPD300 coupling device for insulation monitoring. The product can monitor the insulation resistance of the positive and negative poles of the DC ungrounded system online. When the insulation resistance is lower than the set value, it will issue a prewarning or alarm signal.
AIM-D500-CA uses the signal injection method for monitoring, which is applicable to the CCS (Combined Charging System) charging standard and the CHAdeMO charging standard. Among them, CCS is widely used in the fast charging system of electric vehicles in Europe and the United States, and CHAdeMO is mainly used in the fast charging interface of electric vehicles in Japan.
The products can also be used in DC systems such as power plants, DC panels of substations, electric vehicle charging devices, UPS power supply systems and other DC power grids.
