Introducing WEM3050T

Purchase Links:


The WEM3050T, released by IAMMETER in August 2023, is a new 3-phase energy meter. It supports both three-phase and split-phase usage, boasting a more compact 2P package similar to the WEM3080.

The WEM3050T has all the functionalities of the WEM3080T, excluding the IAMMETER-cloud service.

Due to the lack of default IAMMETER-cloud service, the WEM3050T is priced more affordable than the WEM3080T.
