1.General：
AIM-D100-T series DC insulation monitoring device can be applied in 10 ~ 1000V DC systems for online monitoring of insulation resistance of positive and negative poles of DC ungrounded system, and sending warning or alarm signal when the insulation resistance is lower than the set value.
The product can be applied to DC systems such as DC panels of power plants and substations, electric vehicle charging devices, UPS power supply systems, photovoltaic DC systems, energy storage systems and other DC power grids.
2. Functions:
• Resistance monitoring. The product can monitor the insulation resistance of the positive and negative poles of the DC system to ground. When the insulation resistance is lower than the set warning and alarm values, it can send out warning and alarm signals;
• Voltage monitoring. The product can monitor the voltage between the positive and negative poles of the DC system and the voltage between the positive and negative poles with respect to ground;
• Overvoltage and undervoltage alarm function. The product can monitor the voltage fluctuation of the DC system, when there is overvoltage or undervoltage, it can issue an alarm signal in time;
• Early warning alarm function. The product has two groups of independently adjustable set values, you can set the warning value and alarm value;
• LED indication function. The product panel has LED indicators of operation, communication and fault, overvoltage, undervoltage, which can display the status of the product;
• LCD display function. The product adopts a 128*32 dot matrix liquid crystal display, which can display parameter information;
• Relay output function. The product has 3-channel relay outputs, which can be selected as normally open or normally closed mode;
• Event log function. The product can record the alarm time and fault type, which is convenient for personnel to troubleshoot;
• Communication network function. The product has 1 RS485 interface and adopts Modbus-RTU protocol, which can be used for data interaction;
• Rail mounting. The product adopts standard 35mm rail mounting;
• Plug-in terminals. The product adopts plug-in terminal wiring, which is convenient for wiring and installation;
