4 channels DC current 0-12A input RS485 interface Din rail moutning

AGF Series, Detect states of solar cell modules, the current of photocell, the state of Surge Protection Devices RS485(Modbus)

1. General

       AGF Series, the analyzer of the solar junction box, is a universal measurement and analysisdevice for the equipement in the solar junction box. They can realize detecting the states of solar cell modules, the current of photocell, the state of Surge Protection Devices, the state of DC breaker and outputing contact signal in photovoltaic power system.       And they all have interfaces with air velocity transducer, temperature sensor, ectroirradiator. They are also equiped RS485(Modbus) port for transfering all data to master device, Such as computer or PLC.

2. Charateristics

1)Their measurement conponents are isolated Hall sensor; 2)They accept Positive and negative junction;3)With special photovoltaic fuse, DC1kV withstand voltage; 4)Option of voltage measurement, up to DC1kV;5)With interfaces with external sensors;6)With one RS485 port;7)Option of many types of power supply.
