Visualizing energy consumption is the first step toward energy savings. Install Eco-POWER METERs in lighting equipment, air conditioners, and production equipment to measure power consumption and check the current status. Then, with specific targets in place, the implementation and management of an energy savings plan is quick and simple. Visualizing target achievments improves the energy usage cycle and allows for changes to be made to maximize efficiency. Inverter air-conditioning power consumption Refrigerating power consumption and temperature* * When analog input is used Lighting power...

USEFUL FUNCTIONS Micro-power measurement function You can even visualize standby power Standby power is a key to saving energy By understanding both operating power and standby power, you can reduce non-operational energy wastage and initiate power-saving activities that go beyond what was formerly possible. KW2G and KW2G-H can also measure fine currents. When the load current declines, micro-power measurement mode is automatically activated (auto range switching function). With improvement Measurement of standby power Wastage eliminated Integrated electric power (kWh) Integrated electric...
