PAN 312 is a power analyzer which is used to monitor electrical data to extend the monitoring capability of MAS 711. PAN 312 measures voltage and current in three phases and calculates a number of values, which can be transferred to and presented by MAS 711:
Power
Energy System current
Current in three phases
System voltage
Voltage in three phases
Current unbalance
Voltage unbalance
MAS 711 reads data from the PAN 311 over a serial data link (RS-485/Modbus).
