6.2.3 3-Phase System
The output of the 3-Phase system can be connected for three-phase four-wire (Y type) system
or three-phase five-wire (
△
type) system.
Note
In this 3-phase system, the Master unit is always phase A, Slave1 is always phase B and
Slave2 is always phase C.
Note
87
In this 3-phase system, the output voltage of phase B and C will be set to the same settings
as that for phase A automatically if the Voltage Mode is set to COM. If the Voltage Mode
is set to Multi, phase B and C output voltage can be set individually.
The output frequency of phase B and C is always set to the same frequency as phase A.
The phase difference between phase A and B is always 120 ° and between phase A and
C is always 240 ° .
In this 3-phase system, the waveform generator A or B only can be switched after the system
output off.
Set ‘Master Type’ of the master unit as ‘3 Phase’, then press the [Main] key to return to the main
