Description

The EMA-90N power analyzer has been designed to combine the maximum possible easiness of operations togheter with a wide choice of advanced funtions.
The device measures currents and voltages, energy consumption and power and displays the individual voltage/current harmonics for power quality in accordance with EN 50160.
The accuracy of active energy measurements corresponds to class 0.2 S in accordance with EN 62053-22. The current inputs are connected via external current transformer (.../1A or .../5A) or 333mV or Rogowski probes.
