The measuring element uses a Hall sensor. Isolated measurement can accept positive or negative busbar measurement. The voltage function is optional, with a maximum measuring voltage of DC1KV. It provides an external sensor input interface.A single RS485 interface is standard, and multiple power supply modes are available.
Open-circuit alarm for photovoltaic cell strings. The status detection comes with digital input, which is used to collect the action status of components such as DC circuit breakers and lightning protectors. It is equipped with relay output, which can be set to inching mode for driving the automatic opening and closing of DC circuit breakers. It provides input interfaces for sensors such as temperature, irradiation, and wind speed, and can output DC24V power to supply external sensors. The local nixie tube cyclically displays the input current of each channel and has an automatic shutdown energy-saving display mode. It has an RS485 interface, supports the Modbus RTU communication protocol, and the communication address, baud rate, and data mode can all be freely set.
