Fonrich DC Combiner Box Monitoring System
FR-DCMG DC Monitor Products
Fonrich DC Combiner Box Monitoring System is mainly used in DC transmission, power distribution and other occasions, such as photovoltaic combiner boxes, DC cabinets, telecommunication equipment rooms and communication base stations.
Through RS485 or industrial wireless communication with the host computer, it can realize automatic alarm for abnormal conditions and realtime detection of whether there is a harmful arc in the DC circuit.
