These products are ideally suited for protection and monitoring applications at voltage levels up to 110kV and below.


Technical Features
Employing a high-performance CPU ensures real-time, fast, and reliable protection computing.
It features fully independent measurement and protection channels with isolated analog input sampling, along with specialized analog and digital filtering designs, as well as high-precision AC sampling technology.

Equipped with comprehensive self-check functions, along with complete records of anomalies, events, and operations.
Equipped with event sequence recording and event recall functions, it can store up to 200 event records without data loss, even in the event of power failure.
Provides an Ethernet communication interface and an RS485 serial communication interface, supporting MODBUS/RTU, MODBUS/TCP, 103 Protocol/RTU, and LFP/IEC103 communication protocols.
