Product Details

Description

This Single Phase Wall-Mounted LoRaWAN Electric Meter is an electrical measuring device with wireless connection module, which is widely used to measure the power consumption of homes or factories. Its structure and appearance design meet the industrial control standards, and it has the characteristics of energy saving, strong anti-interference ability and stable operation. Moreover, it uses LoRaWAN wireless technology to make the communication distance longer and the signal more stable, which can well meet the requirements of safe communication. In addition, the equipment supports two-way measurement, which is very suitable for use with solar energy systems, and is widely used in urban, rural and factory fields.

Features

This Single Phase Wall-Mounted LoRaWAN Electric Meter is made of high-quality ABS material, with a full dust-proof and waterproof design, so it has flame retardant and anti-corrosion properties, so it can be used in various environments. At the same time, it is controlled by an imported single chip computer, equipped with dual channel digital isolation chips, and has high electromagnetic immunity and low radiation characteristics to ensure stable use. In addition, it is equipped with a backlight LCD display. After one second of power on, parameters can be fully displayed on the screen, and the backlight is on. The instrument can display the screen completely for 10 seconds through communication command.
