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 power 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 energy usage cycle and allows for changes to be made to maximize efficiency.
