CODE

Q72P3H005MCQ…

Communication protocols Standard Option
ModBus RTU +  
Ethernet-ModBus TCP/Webserver   +
Johnson Controls N2 OPEN   +
Profibus DP v0   +

DESCRIPTION

Compact Multifunction meter suitable for three-phase three or four wires unbalanced load systems.
The QUBO H version performs additional “advanced” measurements which allow a very efficent monitoring and supply further information about the system operating conditions.
