1-1 Features

■KW4M Eco-POWER METER is a wattmeter in DIN48 size. Electrical energy (voltage, current, etc.) is
measured using AC voltage and AC current input via one of the following systems: single-phase
two-wire system, single-phase three-wire system, or three-phase three-wire system.
This also works as an hour meter, that is measured power-on or power-off time, and as a counter that
is for pulse output equipment like flowmeter.
■Eco-POWER METER is designed chiefly to manage saving energy. It is neither intended nor
can it be legally used for billing.
