Acrel AIM-M300 Medical Intelligent Insulation Monitor
Acrel AIM-M300 Medical Intelligent Insulation Monitor
General
Acrel AIM-M300 medical intelligent insulation monitor the insulation resistance of medical IT system, At the same time, the load current and temperature of the IT system transformer is monitored. In combination with ASG100, AIL100 series insulation fault locators and the appropriate measuring current transformers, the AIM-M300 is designed to support insulation fault location.AIM-M300 series medical intelligent monitoring device adopts advanced micro-controller technology, which has high integration, compact size, convenient installation and integrates intelligence, digitalization and networking in one. It is suitable for insulation monitoring of isolation power system in Class 2 medical locations such as operating room and intensive care unit.
Wiring
24V, G for the auxiliary power supply, and L1, L2 are connected to the IT system (which can be connected to the two output terminals of isolation transformer). I0, I1 for the current transformer signal input, and T0, T1 as the temperature sensor signal input. KE, FE are the functional grounding wires, which should be connected to the on-site equipotential terminals by two independent wires.
