GYDCG-UBCH1 single plug DC Insulation Monitoring Device (IMD) For DC charging pile,Din Rai
Description
GYDCG-UBCH1 series products are insulation monitoring devices that integrate various high-voltage monitoring functions, including DC-to-ground insulation resistance monitoring (real-time monitoring of positive and negative pole-to-ground insulation resistance), DC voltage monitoring and reverse connection alarm, DC voltage monitoring on the vehicle side and reverse connection alarm, current shunt voltage monitoring and other safety monitoring functions. It can be used in DC systems such as electric vehicle DC charging systems, photovoltaic systems, energy storage systems, and DC grids.
This product has the insulation monitoring start-stop function. After the insulation monitoring is started, it can monitor the insulation resistance of the positive and negative electrodes to the ground in real time. The monitoring results are not affected by DC voltage fluctuations, and are not affected by the symmetry of the positive and negative insulation resistance. (GYDCG-UBCH1 is larger than GYDCG-UBC1 model).
