EZD

The EZD electronic energy meter is used to detect the energy consumption of three-phase consumers (regardless of load) in industrial plant, workshops, machines, offices, etc. Both plant with burst firing controls (intermittent power consumption) and distorted sine waves can be metered. It can display and save the value of the energy consumed, output it in pulse format for further processing and display the instantaneous active power via an analogue output (20 mA).
