Functionally it is same as 43** but the difference is in measurement. It measures true RMS values and indicates average demand, instantaneous demand, voltage and current all at a time. The integration period can be selected as 15 min or 30 min. There are 3 selectable settings to energize the 3 potential free relays. This help sin controlling demand in optimized way. It stores 120 readings at interval of 30 min. which can be logged to PC.
