The CPM-20 series Multifunction Power Meter provide high accuracy measurement,
display and communication(Modbus RTU) of all electrical and power quality
parameters, including harmonic measurement THD(Total Harmonic distortion
2nd~31st)
Provides electricity bill ratio (Cost) and CO set can show
2
cumulative electricity bills and carbon emissions, and suitable for the installation in
the power management of remote communication, such as the use of demand.
Demand readings ,digital input / output (DI / DO), measured values(Max / Min)
recording...
Control panels and Motor, Generator monitoring Switchgear distribution systems ,
