[High Cost-Effectiveness] GYDCG-UBCS1

GYDCG-UBCS1 DC Insulation Monitor features an insulation monitoring start/stop function. Once activated, it continuously monitors the positive and negative poles-to-ground insulation resistance. Monitoring results are unaffected by DC voltage fluctuations or the symmetry of positive and negative insulation resistance.

• Monitors positive and negative poles-to-ground insulation resistance in 100–1000VDC floating DC systems.
• Resistance measurement range: 0KΩ–10MΩ.
• DC voltage monitoring range: 0–1000VDC.
• Supports RS485 communication with MODBUS RTU protocol.
• Features a DC reverse-polarity alarm function.
• Supports two operating modes: Automatic Bridge Switching Mode (unbalanced bridge method) for monitoring insulation resistance to ground, and Fixed Bridge Mode (balanced bridge method) for monitoring voltage to ground.
• Features an internal self-test function for the insulation monitoring module.
• Suitable for EV DC charging systems, photovoltaic systems, energy storage systems, DC power grids, and other DC systems.
