Product description
FR-DCMG DC monitor products are mainly used in DC power transmission and distribution,
such as photovoltaic combiner boxes, DC cabinets, telecommunications equipment rooms
and communication base stations. It communicates with the host computer through RS485
or industrial wireless. Its main function is to monitor the current of each branch in the DC
system, the bus voltage, the temperature of the cabinet, the status of the lightning arrester
and the status of the DC breaker. It can realize automatic alarm for abnormal conditions and
real-time detection of the presence of harmful arcs in the DC circuit.
Main Features
•
Monitoring function: Real-time monitoring of the generation current, voltage,
temperature of the combiner box, lightning arrester status, DC circuit breaker status,
and DC arc fault status of each photovoltaic string in the combiner box, and
communicate with the host computer through RS485.
•
Display content: For the detected voltage, current, temperature, switching state,
power generation and other data, the FR-DCMG-MMPU can display a histogram
interface through the LCD to read the current and other data more intuitively.
•
Alarm function: It can be configured to open or close the alarm according to the
actual needs of the scene. When the alarm occurs, the interface will pop up an alarm
message.
•
Current calibration: identify zero drift and improve the accuracy of current
identification. (Default off)
