FR-DCMG-AS4A

Model: FR-DCMG-AS4A
Manufacturer: Fonrich
Description: Hall sensor AS4A with arc function DC arc detector
Fonrich arc detector detects in real time whether a fault arc occurs in the DC circuit. Once a fault arc occurs, it immediately sends out an alarm signal to cut off the fault circuit. It can also accurately locate the arc risk and effectively prevent safety hazards such as fire caused by the arc.
DC Arc Detection:
Identify string/parallel arcs and discover potential risks in time
Used together with Fonrich PV module optimizer and smart gateway, it can realize module-level rapid shutdown
Stable performance:
Perforated design to isolate signal interference between channels
Supports up to 24 channels
Installation method:
Guide rail installation in DC combiner box, or customized intelligent arc protection box
Features:
– Modular design, each module can support 4 channels simultaneously；
– Independent arc detection for each channel, arc alarm threshold can be set；
– Integrated current measurement function；
– Modbus interface with standard protocol to indicate faulty arc channels；
– Support module cascade connection, the number of cascading can support up
to 6 cascaded modules for a total of 24 channels；
– PLC compatible with SunSpec Standard RSD；
– Long string circuit support, with a maximum support of 1600m;
– PV rail mounting design, easy and reliable installation；
– Conform with UL1699B (Type 1);
