MultiDigit M84x three phase LED power meters are housed in round barrelled, square fronted cases.

They measure Volts, Amps, Frequency, Demands, Maximum Demands, Active Power, Reactive Power, Apparent Power, Active Energy, Reactive Energy, Real Power Factor and THD on voltages and currents.

They feature the option of pulsed output and an RS485 port using a subset of Modicon's Modbus protocol.

Their accuracy is class 0.2% for input signals down to 10% Un and 10% In, (1% of reading for energy measurements. IEC1036), 50-60Hz.
