Gems 3500 is installed in the distribution board and switchboard that supplies power to factories, building ID centers, etc., and measures the voltage and current of the incoming and outgoing branches to determine the electrical energy consumption pattern for each detailed unit through power and wattage calculation. to improve equipment processes and contribute to energy savings. All the acquired status measurement information is provided to the host system by Ethernet or serial communication and controlled as necessary to enable efficient power management operation. The effect of this is as follows.

1) Autonomous operation possible to maintain the optimum indoor temperature according to the forced energy allocation method.

2) It is possible to calculate carbon emission by unit part.

3) Energy cost allocation and waste factor identification function by measuring the amount of electricity per process/time.

4) Detailed unit wattage monitoring and wattage usage analysis and statistics function.

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

6) Greenhouse gas energy target management and carbon credit market preparation possible.

7) Energy saving possible through process improvement.

8) Accurate trends and statistics by factory/building/department are possible, so it is possible to motivate energy saving by inducing a competitive spirit
