2.Main Features

Control power supply:

HI control power is 90-300VDC and 70-265VAC(48-62Hz),suitable for power systems of different voltage levels.

Phase CT auxiliary:

With 5A phase CT auxiliary,it can accurately measure the current parameters of the generator.

Analog output:

The analog output is 4 to 20mA,which can be used for signal transmission in remote monitoring and control systems.

Basic display function:

The relay is equipped with basic display function,which can display the operating status and fault information of the generator.

Programmability:

The relay has a programmable function,and the user can set the parameters and logic of the relay according to the specific application requirements,so that it can adapt to different generator systems and operating environments.

Communication function:

Supports a variety of communication protocols and interfaces,such as Modbus,Profibus,etc.,to facilitate data exchange and remote monitoring with other devices or systems.

High reliability:

After strict quality control and testing,it ensures stable operation even in harsh industrial environments.
