The DTS193 and DSS193 series electronic three-phase energy meters both adopt new microelectronics technology and are used to measure three-phase AC active energy with a rated frequency of 50/60HZ. They are equally used for measuring forward and reverse electricity consumption.

There are two ways to connect this series of electronic three-phase electricity meters: direct connection or connection through a transformer. This product complies with all the technical requirements for electronic three-phase energy meters in the national standard GB/T17215.321-2021 "Level 1 and Level 2 Static AC Active Energy Meters".
