[2000V System] GYDCG-UBCW2K

Description

GYDCG-UBCW2K Series High Voltage DC Insulation Monitor

GYDCG-UBCW2K series high-voltage DC insulation monitors can monitor the insulation resistance between the positive/negative poles and ground in real time after the module is powered on and insulation monitoring is enabled. The monitoring results are not affected by DC voltage fluctuations or the symmetry of positive and negative insulation resistance.

The GYDCG-UBCW2K-RS and GYDCG-UBCW2K-RSA models support module control and data reading through RS485 communication. After power-on, the insulation monitoring function is disabled by default.

The GYDCG-UBCW2K-A (without communication) and GYDCG-UBCW2K-ARS models enable insulation monitoring by default after power-on.

• High Voltage DC System Monitoring: Monitors insulation resistance between positive and negative poles and ground in 100~2000VDC floating DC systems.
