Description

DWM-DE53LR is an external open-close transformer rail-type multifunctional anti-backflow meter based on Sub-1G(LoRaWAN Default) wireless transmission which is suitable for power monitoring of distributed photovoltaic grid-connected cabinets, power demand side management and other applications. It has the characteristics of no need to dismantle the busbar once, simple and convenient wiring, safe construction, and saves the transformation cost for users. 

The device integrates the measurement of all power parameters and the function of power monitoring. In the meanwhile, there are RS-485 communication interface and Sub-1G(LoRaWAN Default) wireless communication interface for users to choose. It adopts the Modbus-RTU protocol to meet the needs of communication network management, and the remote on-off function of the circuit breaker switch can be implemented by the four relay outputs; It uses the OLED display interface to view and control parameter through the panel buttons. It is ideal for real-time power monitoring system and supports BLE near-field wireless communication function. It can connect devices through mobile phones to confi gure parameter and monitor real-time power parameter, which provides great convenience for on-site operation and maintenance and deployment.
