AIM-D500-CA DC insulation monitor is designed for 0-1000V DC systems. It ensures power supply safety by continuously monitoring insulation resistance in IT systems. It warns of potential issues when insulation resistance falls below set values, making it ideal for applications like power plants, substations, EV chargers, UPS, and solar systems.
