[4000V System] GYDCG-UBCW4K

Description

GYDCG-UBCW4K series high-voltage DC insulation monitors can monitor the insulation resistance between the positive and negative poles and ground in real time after the module is powered on and enabled. The monitoring results are not affected by DC voltage fluctuations or the symmetry of positive and negative insulation resistance.

The GYDCG-UBCW4K-RS and GYDCG-UBCW4K-RSA models support module control and data reading through RS485 communication. After power-on, the insulation monitoring function is disabled by default.

The GYDCG-UBCW4K-A (without communication) and GYDCG-UBCW4K-ARS models enable the insulation monitoring function by default after power-on.

• Monitors insulation resistance between positive and negative poles and ground in 1000~4000VDC floating DC systems.

• Resistance measurement range: 0KΩ~50MΩ.

• DC voltage detection range: 0~4000VDC.

• DC voltage reverse connection alarm function.

• Built-in self-test function of the insulation monitoring module.

• Supports RS485 communication with MODBUS RTU protocol.

• Equipped with dry contact relay output alarm function.

• Suitable for DC systems such as DC charging systems, photovoltaic systems, energy storage systems, and DC power grids.
