Product Description

GYID series insulation monitoring device is used to monitor the insulation resistance of 0~1000Vd.c. DC floating system and 0~750Va.c. AC floating system to ground in real time; measure the insulation fault of equipment shell to ground, high voltage to the shell, etc.

In the DC system, the insulation resistance of the positive pole and the negative pole of the DC system to the ground can be independently measured. In specific electric vehicle applications, CAN bus DC insulation monitor can also be reliably monitored under strong interference or complex driving conditions, such as acceleration/deceleration, braking, and energy recovery.
In the AC system, an Electric Vehicle DC insulation monitor can suppress the interference of voltage high-frequency harmonics, and accurately measure the insulation resistance of the entire AC system to the ground.
 

 

Feature

* DC system: monitor the ground insulation of the 0~1000Vd.c. DC floating system

 

* AC system: Monitor the ground insulation of 0~750Va.c. AC floating system

* Passive equipment: monitor the insulation status between the equipment and the housing or between the equipment and the ground

* When the bus voltage is 0, the insulation resistance of the system to the ground can still be reliably monitored

* Measuring range 0~50 MΩ, when it exceeds 50 MΩ, the default output is 50 MΩ

* Automatic adaptation system Y capacitor CY (CY≤4 μF)

* CAN bus interface

* Built-in high-voltage relay can disconnect the physical connection between the terminal (DC+/DC-) of the insulation monitor and the system under test
