A-RING COB
As electrical devices become increasingly compact and safety requirements become more stringent, reliable leakage current detection has become a key element of electrical protection systems. Early detection of leakage current helps prevent the risk of electric shock, equipment damage, and fire caused by insulation faults.
COBON TECH’s A-RING COB module is designed to detect AC/DC leakage current quickly and reliably. With low power consumption, excellent noise immunity, and a compact integrated design, it can be easily incorporated into electrical protection devices and provides stable and reliable fault detection performance.
It is suitable for monitoring AC/DC leakage current in EV charging equipment and various electrical protection systems.
