19D-NX 240Vac Kwh-meter 240v Electric Din Rail Dc Power Smart Wifi Energy Meter Lcd Screen
19D-NX Modular multi-function meter is Blue Jay next generation din-rail meter power meter. Using 3M width expand model can build max 40x3P4W or 120x1P2W energy metering system. Flexible selection of different modules can build the most suitable on-site integrated metering device. The 19D-NX Meter uses CTs connect, and provides max 0.5 class metering accuracy. The default is RS485 Modbus-RTU port. Furthermore, customized expand module can provide extra IoT module valid for different project.
