Acrel AIM-T300 Industrial Isolated Monitoring Device
Acrel AIM-T300 Industrial Isolated Monitoring Device
General
Acrel AIM-T300 Industrial Isolated Monitoring Device recognizes insulation faults and immediately reports that the value has fallen below the minimum. This prevents operational interruption caused by a second, more severe insulation fault.

Application of Industrial IT Isolated Power System?
Industrial IT isolated power system is specially developed by ACREL for IT power distribution systems in industrial occasions such as mines, glass plants, electric furnaces and test equipment, ships, metallurgical plants, chemical plants, explosion-hazardous places, computer centers and emergency power supplies. The system has rich functions, including insulation resistance monitoring, insulation fault early warning, insulation fault alarm, event recording, parameter setting, communication networking, etc. When the system has a ground fault, it can alarm in time, and accurately locate the specific circuit where the fault occurs, so as to Remind the relevant personnel to troubleshoot the fault in time.
Acrel Industrial IT Isolated Power System FAQs
With the development of industrial science and technology, residual current poses a great threat to industrial production safety. In order to improve the continuity and reliability of power supply, many important production sites adopt IT distribution system (ungrounded system).
Mine, glass factory, electric furnace and test equipment, ship, metallurgical plant, chemical plant, explosion hazard site, computer center and emergency power supply.
Real-time monitoring of the ground insulation resistance of the IT system, and start the fault warning or alarm function when the resistance exceeds the limit.
Insulation monitoring and fault determination of power distribution system, providing safe, reliable and continuous power distribution.
