2022 Good Quality Charging Pile Management System - JSY-MK-229 Single channel AC / DC electric energy metering module – JIAN SI YAN

Description

Jsy-mk-229 DC charging pile electric energy measurement module aims at the inconvenience of the traditional wall mounted electric energy meter in the field use and installation, and designs a miniature guide rail mounted electric energy meter, which has the advantages of high measurement accuracy, strong overload capacity, stable and reliable performance, wide working voltage range and low power consumption. And its small size, light weight, modular structure, can be used with miniature circuit breakers installed in the distribution box to achieve terminal distribution energy measurement.
