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.

Every electricity bill lists a number followed by “kWh” — but what does it truly represent? In energy metering, a unit of energy typically used for metering is the kilowatt-hour. While physicists think in joules, utilities and smart meters rely on this practical block to quantify consumption, dete...
Read MoreCurrent transformers are among the most precisely engineered components in power measurement and protection systems. Yet their internal structure is rarely examined in detail. Understanding what is inside a current transformer, how each part is selected, and why different construction types exist g...
Read MoreEvery time a household appliance runs, a factory machine operates, or a commercial building draws power from the grid, an invisible process of measurement takes place in real time. The device responsible for this measurement is the energy meter — one of the most consequential yet least understood i...
