AIM-D500-CA DC Din Rail Insulation Monitoring Device
Insulation Resistance Monitoring of DC Charging Station
-
Acrel AIM-D500-CA DC insulation monitor is a cutting-edge device designed for 0-1000V DC systems, ensuring power supply safety by continuously monitoring insulation resistance in IT systems.It meets the requirements of IEC 61557-8 and is compatible with the Combined Charging System (CCS) and CHAdeMO 3.0 standard.It can monitor the insulation resistance of DC charging stations with a nominal system voltage range from 50V up to 1000V.The device features a four-module enclosure and DIN-rail mounting, making it easy to install and integrate into existing systems.It also has the capability to measure system voltage and detect undervoltage and overvoltage conditions.Its stop mode allows users to disable the measuring pulse generator via the Modbus protocol, through the device menu, or by using an external button.The AIM-D500-CA is an ideal solution for applications such as power plants, substations, EV chargers, UPS systems, and solar systems.
