General
Acrel Din Rail Three Phase AC Energy Meter is a smart meter
designed for power supply systems, industrial and mining
enterprises and utilities to measuring electricity consumption and
manage the electric demand. It features high precision, small size
and simple installation. It integrates the measurement of all
electrical parameters with the management provides various data on
the previous 48 months, checks the 31st harmonic content and the
total harmonic content. Technical parameter
