Product Overview


Product Description

     The GYDCG-UBCH2 model product is a device for online monitoring of the insulation resistance value of the positive and negative poles of the DC floating system to the ground. The roads are independently controlled and can be monitored at the same time without interfering with each other. The user can realize the start and stop of a certain insulation monitoring and the acquisition of the value through RS485 communication. This product can monitor positive and negative symmetrical and asymmetrical insulation resistance, and can accurately measure the resistance value under the condition of DC voltage fluctuation.
    After the product is turned on, it can continuously and real-time monitor the insulation resistance, and the user can read the current insulation resistance value at any time after it is turned on. This product can also monitor the DC voltage value at the same time, the current voltage value can be read in real time after it is turned on, and the voltage value read is 0 after it is turned off. If the DC voltage is not 0, the user can also determine whether the product is currently on or off by checking whether the current voltage value is 0.
    After the product is turned off, the high-voltage switch is disconnected, and the product is completely separated from the DC and the earth.
