**Three phase power-meter**

</WRAP>

^ Used for measuring power and energy of                ||
| ✔ | three-phase energy sources                        |
| ✔ | three-phase energy consumers                      |

</WRAP>

===== Applications =====

* Digital multi-function energy meter for or 3-phase sources or consumers

===== Features =====

* Three phase direct connection up to 80 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. 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.
