RCMB-H50
In power conversion systems such as solar inverters, energy storage systems (ESS), and industrial power conversion equipment, AC and DC leakage currents can occur due to insulation deterioration, cable damage, abnormalities in internal power semiconductors, as well as parasitic capacitance within the system. Reliable leakage current monitoring plays an important role in protecting equipment, improving system reliability, and meeting electrical safety requirements.

COBON TECH’s AC/DC Leakage Current Monitoring Module continuously monitors AC and DC leakage currents using Fluxgate sensing technology. It provides high measurement accuracy, excellent long-term stability, and reliable fault detection performance. Optimized for high-current power conversion systems, it also supports fast response times, self-diagnostic functions, and communication interfaces, allowing easy integration into protection and monitoring systems.

It is suitable for solar inverters, PCS (Power Conversion Systems), ESS (Energy Storage Systems), renewable energy systems, and other industrial power conversion equipment.
