Suzhou Gongyuan Automation Technology Co., Ltd. | Electrical Safety Monitoring for New Energy Systems
GYIM-DAR
• TUV-CE certified.
• Full-featured: Supports insulation resistance monitoring, DC voltage monitoring, reverse voltage alarm, resistance threshold alarm, voltage-to-ground monitoring, and PE wire disconnection detection.
• Compatible with 12VDC or 24VDC power supply.
• Resistance monitoring range: 0KΩ~10MΩ.
• Real-time insulation resistance monitoring, unaffected by the symmetry of positive and negative insulation resistance, with real-time data updates.
• Higher reliability: Insulation resistance monitoring results are not affected under low-frequency DC voltage fluctuations.
• Larger internal ground resistance.
• Fast monitoring speed with adaptive ground capacitance, enabling rapid insulation resistance monitoring with a monitoring cycle of 0.7s~2s.
• Higher monitoring accuracy: Under low ground capacitance conditions, monitoring accuracy can reach within 1%.
GYIM-DAR DC Insulation Monitor features insulation monitoring start/stop control. When insulation monitoring is enabled, it can monitor the insulation resistance between the positive and negative poles and ground in real time. The monitoring results are not affected by DC voltage fluctuations or the symmetry of positive and negative insulation resistance.
• Monitors insulation resistance between positive and negative poles and ground in 100~1000VDC floating DC systems.
• Resistance measurement range: 0KΩ~10MΩ.
• DC voltage detection range: 0~1000VDC.
• Supports RS485 communication with MODBUS RTU protocol.
• DC voltage reverse connection alarm function.
• Supports two operating modes: automatic switching bridge mode (unbalanced bridge method for monitoring insulation resistance to ground) and fixed bridge mode (balanced bridge method for monitoring voltage to ground).
• Built-in self-test function of the insulation monitoring module.
• Suitable for DC systems such as electric vehicle DC charging systems, photovoltaic systems, energy storage systems, and DC power grids.
