Description

Our Wireless DC Power Meters are mainly used for three-phase active energy metering in low voltage grids and have the advantages of small size, high accuracy and rich functionality. Depending on the use scenario, they have various communication functions such as RS485 communication, NB, 4G, etc. A new current sampling method using an external transformer has also been added. At the same time they are compact and easy to install without taking up too much space. You can install them in distribution boxes, thus realising the requirements of sub-metering, operation and maintenance supervision or power monitoring for different areas and different loads.

Features

Our Wireless DC Power Meters are primarily used for the measurement of all electrical parameters in three-phase circuits, while current inputs can be selected for up to four circuits. They come with a fast-response, multifunctional LCD LED display for high operational accuracy and clear figures. And their strong, flame-retardant housing is robust and prevents deformation during long-term use. In addition, they are equipped with reverse connection protection to ensure safety even in bad weather.
