DC Insulation Monitor, AIM-D100
AIM-D100 DC insulation monitors are mainly used for monitoring of the positive and negative terminal-to-ground insulation resistance in the DC ungrounded systems. When the insulation resistance is lower than the set alarm value, an alarm message can be sent. The DC insulation monitor is based on the unbalanced bridge principle.
This DC insulation monitor can be used in DC systems such as DC EV charging systems, PV solar systems, energy storage systems, and DC power grids.
- Real-time measurement and display of the voltage between the positive and negative terminals in the DC system, also voltage between the positive and negative terminals to the ground, the measuring voltage range is 200V~1000V.
- Monitor the voltage fluctuation of the system in real time, and send alarm signal in time when it is over voltage or under voltage.
- Measure the insulation resistance of the positive and negative terminals to ground real time in the DC system. When the resistance is lower than the set alarm value, the alarm signal will be sent.
- The insulation monitoring response time is adjustable from 3 to 60s.
- There are 2 adjustable relay output to set insulation resistance alarm value, optional N/C or N/O.
- 128*32 LCD display, LED alarm indication.
- Event record function, which can record the time and fault type while alarm occurs, it is convenient for the maintenance operator to analyze the operating status of the system in time.
- RS485 Modbus-RTU protocol, it can realize data exchange of the system.
