Page 7: Product Overview
2 Product Overview 2.1 Description FR-DCBS-AFS8B Arc Fault Protection Box is a solar AFCI (Arc Fault Circuit Interrupter), which is mainly used in middle sizes of distributed PV system, such as 20-200KW rooftop solar system. Functions Its main function is to detect the arc fault of the PV strings and disconnect the string cables when arc fault occurs. -
Page 8: Appearance
2.2 Appearance Dimensions(mm) Ports 2.3 Principles of Design Schematic Diagram If the arc fault is detected, AFS8B will issue an alarm signal by the LCD and RS485. At the same time, the DC relay will be driven to break off the DC circuit. So that the DC circuit is in the state of no current. -
Page 9: Arc Alarm Strategy
2.4 Arc alarm strategy 2.4.1 Arc mode We divide the arcs into Instantaneous Arc and Continuous Arc. Instantaneous Arc The arc duration does not exceed the Instantaneous Arc Time (IAT), and there is no arc occurring again within the Continuous Arc Time (CAT). Continuous Arc The arc duration exceeds the IAT, or the arc duration does not exceed the IAT, but the arc occurs again within the CAT. -
