ECO-POWER METERS

Panasonic Eco-POWER METERS overview Visualizing energy consumption to save energy Install Eco-POWER METERS in lighting equipment, air conditioners, and production equipment to measure pow- er consumption and check the current status. Afterwards, with specific targets in place, the implementation and management of an energy savings plan is quick and simple. Visualizing target achievements improves the ener- gy usage cycle and allows for changes to be made to maximize efficiency. , of an energy saving plan i Energy saving target setting

Performance of Eco-POWER METERS 1) Without terminal block 2) With terminal block 4) Use commercially available current transformers (CT) with secondary currents of 1A or 5A and primary currents of 4000A or less. 5) The Eco-POWER METER is designed chiefly to manage saving energy. It is neither intended nor can it be legally used for billing. 6) Free of charge. For KW Watcher, a Web Datalogger Unit (DLU) is required.
