Basically similar, depending on the parameters BS803 series power parameters andPower quality monitoringdeviceWith various functions such as power quality monitoring, power metering, lightning overvoltage monitoring, communication protocol conversion, etc., this device can be flexibly applied to various environments such as intelligent buildings, substations, power plants, etc. Widely used in fields such as energy conservation and environmental protection, power, and industry. BS803 includes three expansion models: BS803S (single circuit), BS803F (4U multi circuit), and BS803T (distributed).

BS803S is a single circuit version that can install one sampling plugin. Suitable for occasions such as factories, hospitals, and new energy generation that require high power quality; BS803F is a multi loop version that can install 8 sampling plugins. Suitable for occasions with a large number of outgoing lines such as substations and power plants;

BS803T is a distributed version that can install one sampling plugin, but can expand up to seven current collection plugins through the network, used in situations such as coal mines and chemical industries that have special requirements for device heating. The sampling plugin is divided into voltage collection plugin and current collection plugin. The voltage plugin contains 4 voltage channels and 4 current channels, and can expand hardware metering functions. The current plugin contains 8 current channels.
