Figure 4-22: 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:
ALC MODE Automatic Level Control of programmed output voltage. This
mode will use the internal voltage measurements to adjust the
output voltage continuously as needed. This effectively
increases the output accuracy and regulation beyond what is
possible with ALC off.
OL MODE 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.
TRIP DELAY 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.
VOLT SENSE 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.
NO. OUTPUT This field is always set to three to indicate the 3 phase output
configuration of the RS Series.
