The series measures the voltage and current of branch and incoming for up to 12 branches by installing it on the distribution board that supplies power to stores, buildings, etc.

It is possible to understand the electric energy consumption pattern for each detailed unit through the calculation of the amount of electricity used in real time quarterly.

This enables users to operate the distribution board efficiently and helps optimize energy consumption.

The effect of this is as follows.

1. Energy cost allocation and waste factors can be identified by measuring the amount of electricity per process/time

2. Detailed unit power consumption monitoring and power usage analysis and statistics available

3. It is possible to establish an energy saving plan in the correct direction by analyzing energy consumption by department, use, and time period.

4. Energy saving possible through process improvement

5. Real-time management on the go through cloud interworking platform support This equipment is a high-precision multi-power measuring equipment that can accurately analyze and diagnose various problems in energy management and power facilities.
