AGF-D photovoltaic DC cabinet acquisition device is mainly used in photovoltaic DC cabinets. It can measure the output current and voltage of the combiner box with external Hall sensors. At the same time, it can monitor the status of circuit breakers and lightning arresters in DC cabinets. The built-in temperature sensor in the meter can help measure the temperature inside the cabinet, and the forced output of the cabinet can realize the forced air cooling function in the cabinet with automatic temperature control. The device has an RS485 interface for uploading measured and acquired data and device status.
