72x72mm Multifunctio network Analyser + THD
Compact multifunction analyser for use in three-phase three or four wires systems with unbalanced load. The QUBO H version has, in addition to the main quantities of an electrical network (including bi-directional active and reactive energy counting), an additional set of "advanced" measurements that allow more efficient monitoring or provide additional information on the operating status of the system. It has RS485-Modbus RTU communication as standard and, as an option, can be equipped with 1 (or 2 if Serial Communication is not used) programmable alarm output, alternatively as a pulse output for retransmission of active or reactive energy.
