Overview

Product model: DTSU25 M1-A/M1-AL Product introduction: This meter is developed using modern advanced microelectronics technology, computer technology, electrical measurement technology, and data communication technology. It is a new generation of metering device that meets the new requirements of our company for electric energy metering; Suitable for three-phase users such as residents, small shops, and office buildings with centralized remote meter reading needs and relatively concentrated electricity meter installations for household metering. This energy meter adopts a DIN35mm track, which is convenient for installation in centralized monitoring scenarios such as base stations, medium-sized distribution rooms, etc. It has the advantages of high testing accuracy, stable performance, less space occupation, low cost, and easy installation.
