Product Description
4G communication type IoT transparent gateway
1.Product profile
LON300S intelligent three-phase carrier energy efficiency terminal is a key equipment in the low-voltage power line carrier centralized meter reading system. It can automatically copy and store power data of various intelligent instruments, acquisition terminals or modules with carrier communication functions, as well as various carrier communication terminals through the downlink channel. The downlink channel can be low-voltage power line carrier and RS-485 serial communication channel At the same time, it can exchange data with the main station or handheld devices through the upstream channel, which is Ethernet communication mode.
