Chapter 1 Meter Overview
DZS310 is an advanced, smart compact meter with standard Din rail installation. It is widely used in
energy distribution sites, energy management systems and intelligent on-line monitoring systems of
different industries. It supports installation without powering off and can monitor 1 three-phase
channel or 3 single-phase channels. And it measures electric parameters i.e. three-phase voltage,
three-line voltage, three-phase current, active power, reactive power, apparent power, power factor,
frequency, active energy, reactive energy etc. with high accuracy.
