Class S IP65 Three Phase Power Quality Analyser for Pole Mount or other Rugged Applications


• 4 current inputs, physical measurement of current in the neutral conductor.
• Registration of up to 1100 parameters, including average, maximum, minimum and instantaneous values.
• Built-in heater, stable operation at low temperatures down to -20ºC.
• Internal rechargeable battery, autonomy of the meter (min. 6 hours).
