General description

The PM-3-IQ is intended for energy measurements in three-phase electrical power network and can be used in residential, industrial and utility applications. Meter measures energy directly in 4-wire networks according to the principle of fast sampling of voltage and current signals.

Connecting terminals can be sealed up against non-authorized access with protection covers. They are built to be fastened according to EN 60715 standard. Meter has built-in RS485 serial communication with the MOD-BUS protocol which enables data transmission and thus connection of the measuring places into the network for the control and management with energy.
