zReal-time measuring data, true RMS

(Three phase voltage, current, active power, reactive power, apparent

power, power factor, frequency, active energy, reactive energy)

zDemand calculation

(Demand and peak demand for current, total active power)

zOptional 2 digital input

zOptional 2 relay output

zAlarm function

z2~31th individual harmonic and THD

zOne RS485, Modbus-RTU protocol
