===== Applications =====

  * Digital multi-function power-sensor for 3-phase sources or consumers

===== Features =====

  * Three phase direct connection up to 65 A
  * Serial RS485 communication
  * Display LCD 7+1 digit
  * Multi-functional front LED

===== 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. Power-sensor 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. Power-sensor has built-in  RS485 serial communication with the MODBUS protocol which enables data transmission and thus connection of the measuring places into the network for the control and management with energy.
