User Manual
4.2.11.2 VOLTAGE/CURRENT CONTROL SETUP menu
The VOLTAGE/CURRENT CONTROL SETUP menu may be used to set output voltage and
current control parameters. These parameters are not frequently changed in the normal
operation of the AC source and are thus located on the UTILITY rather than the PROGRAM
menu.
The following options are available in this menu:
VOLT PAIR
OL MODE
TRIP DELAY
VOLT SENSE
NO. OUTPUT
i Series / iX Series

Figure 4-22: VOLTAGE/CURRENT CONTROL SETUP menu

[iX Series only] The iX Series can be operated in either a
135/270 voltage range pair or a 150/300 voltage range pair. The
amount of current available in the 135/270 range pair setting is
about 10% higher. Unless the extra voltage range is needed, the
maximum current can be attained in the 135/270 volt mode.
This field allows the selection of the most optimal voltage and
current combination for the application at hand.
This field is used to select constant current (CC) or constant
voltage (CV) mode. The constant current mode will limit the
maximum amount of current drawn by the load to the set value.
The voltage will be reduced as needed after the trip delay time
to maintain the level of programmed current.
The constant voltage mode will maintain the set voltage as long
as the current drawn by the load does not exceed the current
limit programmed. If the current limit is exceeded, the output will
be shut off after the trip delay time.
The trip delay field may be used to set the amount of time to
hold off the current limit trip point. The minimum amount of time
is 100 ms or 0.1 sec. The maximum amount of time is 5.00 sec.
This field selects the internal or external sense line inputs.
Internal sense does not require the external sense lines to be
connected as sensing occurs at the output relay of the AC
source. For best results, connect the external sense lines and
select the EXT sense mode in this field. This will compensate
for voltage drop in the cables to the load. The measurements
are also taken at the sense points, so the external sense mode
should be used for best measurement results.
This field is only accessible if the phase mode option is installed.
It allows the number of output phases to be toggled between
single and three phase mode. In single phase mode, all power is
available on phase A. The Mode-iX option is available to route
all power to a single output terminal pair.
