Feature

  •  Resistance monitoring. The product can monitor the insulation resistance of the positive and negative poles of the DC system to the 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. The measurement range is 0~1000V.
  •  Current monitoring function. The product can monitor the current of DC system, only the AIM-D100-CAI model has this function.
  •  LED indication. The product panel has operation, communication, and fault LED indicators to display product status.
  •  Communication networking function. The product has RS485 interface and adopts Modbus-RTU protocol for data exchange.
  • Metal casing. The product adopts a metal shell and can be wall-mounted or installed using accessory rails.
  •  Plug-in terminals. The product adopts plug-in terminal wiring, which is convenient for wiring and installation.
