i Series / iX Series
9.5.4 Operation
9.5.4.1 General
The Mode-iX phase mode controller switches the three outputs from three California Instruments
iX-series power sources to one or three sets of outputs on the phase mode controller. This
allows the three power sources to be operated in either three phase or single phase mode with
the system output being taken from the phase mode controller.
This switching is performed automatically via a control signal on the system interface connector.
The signal is generated by the master power source. The master power source also
automatically configures the complete power system for proper output phase angles and power
source current sharing.
9.5.4.2 Front Panel Controls/Indicators
Power Switch and Lamp
A power switch turns the phase mode controller on or off. A lamp above the switch illuminates
when power is on.
Mode Switch
This momentary contact push button switch toggles the phase mode controller between three
phase and one phase mode. The function of this switch is normally disabled and switching is
remotely controlled via a signal on the system interface connector.
One Phase Lamp
This lamp is illuminated when the phase mode controller is operating in single phase mode. The
power source outputs connected to the SOURCE A, B and C terminals are shorted together in
the phase mode controller and directed to the LOAD A terminal.
Three Phase Lamp
This lamp is illuminated when the phase mode controller is operating in three phase mode. The
power source outputs connected to the SOURCE A, B, C terminals are directed to the LOAD A,
B, C terminals, respectively.
Programmed Control
The phase mode controller is normally remotely programmed by the master iX-series power
source.
A system interface cable must be connected between the Mode-iX and the power sources to
carry the control signal to the Mode-iX. When configured for programmed control, the Mode-iX
may not be controlled by the front panel MODE switch. Refer to Section 4.2.11.2 for details on
controlling the number of output phases with the Mode-iX option.
